Publishing
Publishing messages can be done via HTTP PUT/POST or via the ntfy CLI. Topics are created on the fly by subscribing or publishing to them. Because there is no sign-up, the topic is essentially a password, so pick something that's not easily guessable.
Here's an example showing how to publish a simple message using a POST request:
=== "Command line (curl)"
curl -d "Backup successful 😀" ntfy.sh/mytopic
=== "ntfy CLI"
ntfy publish mytopic "Backup successful 😀"
=== "HTTP" ``` http POST /mytopic HTTP/1.1 Host: ntfy.sh
Backup successful 😀
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/mytopic', { method: 'POST', // PUT works too body: 'Backup successful 😀' })
=== "Go"
go http.Post("https://ntfy.sh/mytopic", "text/plain", strings.NewReader("Backup successful 😀"))
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.sh/mytopic" Body = "Backup successful" } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/mytopic", data="Backup successful 😀".encode(encoding='utf-8'))
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/mytopic', false, stream_context_create([ 'http' => [ 'method' => 'POST', // PUT also works 'header' => 'Content-Type: text/plain', 'content' => 'Backup successful 😀' ] ]));
If you have the Android app installed on your phone, this will create a notification that looks like this:
There are more features related to publishing messages: You can set a notification priority, a title, and tag messages 🥳 🎉. Here's an example that uses some of them at together:
=== "Command line (curl)"
curl \ -H "Title: Unauthorized access detected" \ -H "Priority: urgent" \ -H "Tags: warning,skull" \ -d "Remote access to phils-laptop detected. Act right away." \ ntfy.sh/phil_alerts
=== "ntfy CLI"
ntfy publish \ --title "Unauthorized access detected" \ --tags warning,skull \ --priority urgent \ mytopic \ "Remote access to phils-laptop detected. Act right away."
=== "HTTP" ``` http POST /phil_alerts HTTP/1.1 Host: ntfy.sh Title: Unauthorized access detected Priority: urgent Tags: warning,skull
Remote access to phils-laptop detected. Act right away.
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/phil_alerts', { method: 'POST', // PUT works too body: 'Remote access to phils-laptop detected. Act right away.', headers: { 'Title': 'Unauthorized access detected', 'Priority': 'urgent', 'Tags': 'warning,skull' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.sh/phil_alerts", strings.NewReader("Remote access to phils-laptop detected. Act right away.")) req.Header.Set("Title", "Unauthorized access detected") req.Header.Set("Priority", "urgent") req.Header.Set("Tags", "warning,skull") http.DefaultClient.Do(req)
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.sh/phil_alerts" Headers = @{ Title = "Unauthorized access detected" Priority = "urgent" Tags = "warning,skull" } Body = "Remote access to phils-laptop detected. Act right away." } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/phil_alerts", data="Remote access to phils-laptop detected. Act right away.", headers={ "Title": "Unauthorized access detected", "Priority": "urgent", "Tags": "warning,skull" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/phil_alerts', false, stream_context_create([ 'http' => [ 'method' => 'POST', // PUT also works 'header' => "Content-Type: text/plain\r\n" . "Title: Unauthorized access detected\r\n" . "Priority: urgent\r\n" . "Tags: warning,skull", 'content' => 'Remote access to phils-laptop detected. Act right away.' ] ]));
You can also do multi-line messages. Here's an example using a click action, an action button, an external image attachment and email publishing:
=== "Command line (curl)"
```
curl
-H "Click: https://home.nest.com/"
-H "Attach: https://nest.com/view/yAxkasd.jpg"
-H "Actions: http, Open door, https://api.nest.com/open/yAxkasd, clear=true"
-H "Email: phil@example.com"
-d "There's someone at the door. 🐶
Please check if it's a good boy or a hooman.
Doggies have been known to ring the doorbell." \
ntfy.sh/mydoorbell
```
=== "ntfy CLI"
```
ntfy publish
--click="https://home.nest.com/"
--attach="https://nest.com/view/yAxkasd.jpg"
--actions="http, Open door, https://api.nest.com/open/yAxkasd, clear=true"
--email="phil@example.com"
mydoorbell
"There's someone at the door. 🐶

```
=== "HTTP" ``` http POST /mydoorbell HTTP/1.1 Host: ntfy.sh Click: https://home.nest.com/ Attach: https://nest.com/view/yAxkasd.jpg Actions: http, Open door, https://api.nest.com/open/yAxkasd, clear=true Email: phil@example.com

Message title
Supported on: :material-android: :material-apple: :material-firefox:
The notification title is typically set to the topic short URL (e.g. ntfy.sh/mytopic). To override the title,
you can set the X-Title header (or any of its aliases: Title, ti, or t).
=== "Command line (curl)"
curl -H "X-Title: Dogs are better than cats" -d "Oh my ..." ntfy.sh/controversial curl -H "Title: Dogs are better than cats" -d "Oh my ..." ntfy.sh/controversial curl -H "t: Dogs are better than cats" -d "Oh my ..." ntfy.sh/controversial
=== "ntfy CLI"
ntfy publish \ -t "Dogs are better than cats" \ controversial "Oh my ..."
=== "HTTP" ``` http POST /controversial HTTP/1.1 Host: ntfy.sh Title: Dogs are better than cats
Oh my ...
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/controversial', { method: 'POST', body: 'Oh my ...', headers: { 'Title': 'Dogs are better than cats' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.sh/controversial", strings.NewReader("Oh my ...")) req.Header.Set("Title", "Dogs are better than cats") http.DefaultClient.Do(req)
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.sh/controversial" Headers = @{ Title = "Dogs are better than cats" } Body = "Oh my ..." } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/controversial", data="Oh my ...", headers={ "Title": "Dogs are better than cats" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/controversial', false, stream_context_create([ 'http' => [ 'method' => 'POST', 'header' => "Content-Type: text/plain\r\n" . "Title: Dogs are better than cats", 'content' => 'Oh my ...' ] ]));
!!! info
ntfy supports UTF-8 in HTTP headers, but not every library or programming language does.
If non-ASCII characters are causing issues for you in the title (i.e. you're seeing ? symbols), you may also encode any header (including the title)
as RFC 2047, e.g. =?UTF-8?B?8J+HqfCfh6o=?= (base64),
or =?UTF-8?Q?=C3=84pfel?= (quoted-printable).
Message priority
Supported on: :material-android: :material-apple: :material-firefox:
All messages have a priority, which defines how urgently your phone notifies you. On Android, you can set custom notification sounds and vibration patterns on your phone to map to these priorities (see Android config).
The following priorities exist:
| Priority | Icon | ID | Name | Description |
|---|---|---|---|---|
| Max priority |  |
5 |
max/urgent |
Really long vibration bursts, default notification sound with a pop-over notification. |
| High priority |  |
4 |
high |
Long vibration burst, default notification sound with a pop-over notification. |
| Default priority | (none) | 3 |
default |
Short default vibration and sound. Default notification behavior. |
| Low priority |  |
2 |
low |
No vibration or sound. Notification will not visibly show up until notification drawer is pulled down. |
| Min priority |  |
1 |
min |
No vibration or sound. The notification will be under the fold in "Other notifications". |
You can set the priority with the header X-Priority (or any of its aliases: Priority, prio, or p).
=== "Command line (curl)"
curl -H "X-Priority: 5" -d "An urgent message" ntfy.sh/phil_alerts curl -H "Priority: low" -d "Low priority message" ntfy.sh/phil_alerts curl -H p:4 -d "A high priority message" ntfy.sh/phil_alerts
=== "ntfy CLI"
ntfy publish \ -p 5 \ phil_alerts An urgent message
=== "HTTP" ``` http POST /phil_alerts HTTP/1.1 Host: ntfy.sh Priority: 5
An urgent message
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/phil_alerts', { method: 'POST', body: 'An urgent message', headers: { 'Priority': '5' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.sh/phil_alerts", strings.NewReader("An urgent message")) req.Header.Set("Priority", "5") http.DefaultClient.Do(req)
=== "PowerShell"
powershell $Request = @{ Method = 'POST' URI = "https://ntfy.sh/phil_alerts" Headers = @{ Priority = "5" } Body = "An urgent message" } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/phil_alerts", data="An urgent message", headers={ "Priority": "5" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/phil_alerts', false, stream_context_create([ 'http' => [ 'method' => 'POST', 'header' => "Content-Type: text/plain\r\n" . "Priority: 5", 'content' => 'An urgent message' ] ]));
Tags & emojis 🥳 🎉
Supported on: :material-android: :material-apple: :material-firefox:
You can tag messages with emojis and other relevant strings:
- Emojis: If a tag matches an emoji short code, it'll be converted to an emoji and prepended to title or message.
- Other tags: If a tag doesn't match, it will be listed below the notification.
This feature is useful for things like warnings (⚠️, ️🚨, or 🚩), but also to simply tag messages otherwise (e.g. script names, hostnames, etc.). Use the emoji short code list to figure out what tags can be converted to emojis. Here's an excerpt of emojis I've found very useful in alert messages:
|
|
|
You can set tags with the X-Tags header (or any of its aliases: Tags, tag, or ta). Specify multiple tags by separating
them with a comma, e.g. tag1,tag2,tag3.
=== "Command line (curl)"
curl -H "X-Tags: warning,mailsrv13,daily-backup" -d "Backup of mailsrv13 failed" ntfy.sh/backups curl -H "Tags: horse,unicorn" -d "Unicorns are just horses with unique horns" ntfy.sh/backups curl -H ta:dog -d "Dogs are awesome" ntfy.sh/backups
=== "ntfy CLI"
ntfy publish \ --tags=warning,mailsrv13,daily-backup \ backups "Backup of mailsrv13 failed"
=== "HTTP" ``` http POST /backups HTTP/1.1 Host: ntfy.sh Tags: warning,mailsrv13,daily-backup

```
=== "JavaScript"
javascript fetch('https://ntfy.sh/backups', { method: 'POST', body: 'Backup of mailsrv13 failed', headers: { 'Tags': 'warning,mailsrv13,daily-backup' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.sh/backups", strings.NewReader("Backup of mailsrv13 failed")) req.Header.Set("Tags", "warning,mailsrv13,daily-backup") http.DefaultClient.Do(req)
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.sh/backups" Headers = @{ Tags = "warning,mailsrv13,daily-backup" } Body = "Backup of mailsrv13 failed" } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/backups", data="Backup of mailsrv13 failed", headers={ "Tags": "warning,mailsrv13,daily-backup" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/backups', false, stream_context_create([ 'http' => [ 'method' => 'POST', 'header' => "Content-Type: text/plain\r\n" . "Tags: warning,mailsrv13,daily-backup", 'content' => 'Backup of mailsrv13 failed' ] ]));
!!! info
ntfy supports UTF-8 in HTTP headers, but not every library or programming language does.
If non-ASCII characters are causing issues for you in the title (i.e. you're seeing ? symbols), you may also encode the tags header or individual tags
as RFC 2047, e.g. tag1,=?UTF-8?B?8J+HqfCfh6o=?= (base64),
or =?UTF-8?Q?=C3=84pfel?=,tag2 (quoted-printable).
Markdown formatting
Supported on: :material-firefox:
You can format messages using Markdown 🤩. That means you can use bold text, italicized text, links, images, and more. Supported Markdown features (web app only for now):
- Emphasis such as bold (
**bold**), italics (*italics*) - Links (
[some tool](https://ntfy.sh)) - Images (
) - Code blocks (
```code blocks```) and inline code (`inline code`) - Headings (
# headings,## headings, etc.) - Lists (
- lists,1. lists, etc.) - Blockquotes (
> blockquotes) - Horizontal rules (
---)
By default, messages sent to ntfy are rendered as plain text. To enable Markdown, set the X-Markdown header (or any of
its aliases: Markdown, or md) to true (or 1 or yes), or set the Content-Type header to text/markdown.
As of today, Markdown is only supported in the web app. Here's an example of how to enable Markdown formatting:
=== "Command line (curl)"
curl \ -d "Look ma, **bold text**, *italics*, ..." \ -H "Markdown: yes" \ ntfy.sh/mytopic
=== "ntfy CLI"
ntfy publish \ --markdown \ mytopic \ "Look ma, **bold text**, *italics*, ..."
=== "HTTP" ``` http POST /mytopic HTTP/1.1 Host: ntfy.sh Markdown: yes
Look ma, **bold text**, *italics*, ...
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/mytopic', { method: 'POST', // PUT works too body: 'Look ma, **bold text**, *italics*, ...', headers: { 'Markdown': 'yes' } })
=== "Go" ``` go http.Post("https://ntfy.sh/mytopic", "text/markdown", strings.NewReader("Look ma, bold text, italics, ..."))
// or
req, _ := http.NewRequest("POST", "https://ntfy.sh/mytopic",
strings.NewReader("Look ma, **bold text**, *italics*, ..."))
req.Header.Set("Markdown", "yes")
http.DefaultClient.Do(req)
```
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.sh/mytopic" Body = "Look ma, **bold text**, *italics*, ..." Headers = @{ Markdown = "yes" } } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/mytopic", data="Look ma, **bold text**, *italics*, ..." headers={ "Markdown": "yes" }))
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/mytopic', false, stream_context_create([ 'http' => [ 'method' => 'POST', // PUT also works 'header' => 'Content-Type: text/markdown', // ! 'content' => 'Look ma, **bold text**, *italics*, ...' ] ]));
Here's what that looks like in the web app:
Scheduled delivery
Supported on: :material-android: :material-apple: :material-firefox:
You can delay the delivery of messages and let ntfy send them at a later date. This can be used to send yourself reminders or even to execute commands at a later date (if your subscriber acts on messages).
Usage is pretty straight forward. You can set the delivery time using the X-Delay header (or any of its aliases: Delay,
X-At, At, X-In or In), either by specifying a Unix timestamp (e.g. 1639194738), a duration (e.g. 30m,
3h, 2 days), or a natural language time string (e.g. 10am, 8:30pm, tomorrow, 3pm, Tuesday, 7am,
and more).
As of today, the minimum delay you can set is 10 seconds and the maximum delay is 3 days. This can currently not be configured otherwise (let me know if you'd like to change these limits).
For the purposes of message caching, scheduled messages are kept in the cache until 12 hours after they were delivered (or whatever the server-side cache duration is set to). For instance, if a message is scheduled to be delivered in 3 days, it'll remain in the cache for 3 days and 12 hours. Also note that naturally, turning off server-side caching is not possible in combination with this feature.
=== "Command line (curl)"
curl -H "At: tomorrow, 10am" -d "Good morning" ntfy.sh/hello curl -H "In: 30min" -d "It's 30 minutes later now" ntfy.sh/reminder curl -H "Delay: 1639194738" -d "Unix timestamps are awesome" ntfy.sh/itsaunixsystem
=== "ntfy CLI"
ntfy publish \ --at="tomorrow, 10am" \ hello "Good morning"
=== "HTTP" ``` http POST /hello HTTP/1.1 Host: ntfy.sh At: tomorrow, 10am
Good morning
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/hello', { method: 'POST', body: 'Good morning', headers: { 'At': 'tomorrow, 10am' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.sh/hello", strings.NewReader("Good morning")) req.Header.Set("At", "tomorrow, 10am") http.DefaultClient.Do(req)
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.sh/hello" Headers = @{ At = "tomorrow, 10am" } Body = "Good morning" } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/hello", data="Good morning", headers={ "At": "tomorrow, 10am" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/backups', false, stream_context_create([ 'http' => [ 'method' => 'POST', 'header' => "Content-Type: text/plain\r\n" . "At: tomorrow, 10am", 'content' => 'Good morning' ] ]));
Here are a few examples (assuming today's date is 12/10/2021, 9am, Eastern Time Zone):

Webhooks (publish via GET)
Supported on: :material-android: :material-apple: :material-firefox:
In addition to using PUT/POST, you can also send to topics via simple HTTP GET requests. This makes it easy to use a ntfy topic as a webhook, or if your client has limited HTTP support (e.g. like the MacroDroid Android app).
To send messages via HTTP GET, simply call the /publish endpoint (or its aliases /send and /trigger). Without
any arguments, this will send the message triggered to the topic. However, you can provide all arguments that are
also supported as HTTP headers as URL-encoded arguments. Be sure to check the list of all
supported parameters and headers for details.
For instance, assuming your topic is mywebhook, you can simply call /mywebhook/trigger to send a message
(aka trigger the webhook):
=== "Command line (curl)"
curl ntfy.sh/mywebhook/trigger
=== "ntfy CLI"
ntfy trigger mywebhook
=== "HTTP"
http GET /mywebhook/trigger HTTP/1.1 Host: ntfy.sh
=== "JavaScript"
javascript fetch('https://ntfy.sh/mywebhook/trigger')
=== "Go"
go http.Get("https://ntfy.sh/mywebhook/trigger")
=== "PowerShell"
powershell Invoke-RestMethod "ntfy.sh/mywebhook/trigger"
=== "Python"
python requests.get("https://ntfy.sh/mywebhook/trigger")
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/mywebhook/trigger');
To add a custom message, simply append the message= URL parameter. And of course you can set the
message priority, the message title, and tags as well.
For a full list of possible parameters, check the list of supported parameters and headers.
Here's an example with a custom message, tags and a priority:
=== "Command line (curl)"
curl "ntfy.sh/mywebhook/publish?message=Webhook+triggered&priority=high&tags=warning,skull"
=== "ntfy CLI"
ntfy publish \ -p 5 --tags=warning,skull \ mywebhook "Webhook triggered"
=== "HTTP"
http GET /mywebhook/publish?message=Webhook+triggered&priority=high&tags=warning,skull HTTP/1.1 Host: ntfy.sh
=== "JavaScript"
javascript fetch('https://ntfy.sh/mywebhook/publish?message=Webhook+triggered&priority=high&tags=warning,skull')
=== "Go"
go http.Get("https://ntfy.sh/mywebhook/publish?message=Webhook+triggered&priority=high&tags=warning,skull")
=== "PowerShell"
powershell Invoke-RestMethod "ntfy.sh/mywebhook/publish?message=Webhook+triggered&priority=high&tags=warning,skull"
=== "Python"
python requests.get("https://ntfy.sh/mywebhook/publish?message=Webhook+triggered&priority=high&tags=warning,skull")
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/mywebhook/publish?message=Webhook+triggered&priority=high&tags=warning,skull');
Publish as JSON
Supported on: :material-android: :material-apple: :material-firefox:
For some integrations with other tools (e.g. Jellyfin, overseerr), adding custom headers to HTTP requests may be tricky or impossible, so ntfy also allows publishing the entire message as JSON in the request body.
To publish as JSON, simple PUT/POST the JSON object directly to the ntfy root URL. The message format is described below the example.
!!! info
To publish as JSON, you must PUT/POST to the ntfy root URL, not to the topic URL. Be sure to check that you're
POST-ing to https://ntfy.sh/ (correct), and not to https://ntfy.sh/mytopic (incorrect).
Here's an example using most supported parameters. Check the table below for a complete list. The topic parameter
is the only required one:
=== "Command line (curl)"
curl ntfy.sh \ -d '{ "topic": "mytopic", "message": "Disk space is low at 5.1 GB", "title": "Low disk space alert", "tags": ["warning","cd"], "priority": 4, "attach": "https://filesrv.lan/space.jpg", "filename": "diskspace.jpg", "click": "https://homecamera.lan/xasds1h2xsSsa/", "actions": [{ "action": "view", "label": "Admin panel", "url": "https://filesrv.lan/admin" }] }'

Action buttons
Supported on: :material-android: :material-apple: :material-firefox:
You can add action buttons to notifications to allow yourself to react to a notification directly. This is incredibly useful and has countless applications.
You can control your home appliances (open/close garage door, change temperature on thermostat, ...), react to common monitoring alerts (clear logs when disk is full, ...), and many other things. The sky is the limit.
As of today, the following actions are supported:
view: Opens a website or app when the action button is tappedbroadcast: Sends an Android broadcast intent when the action button is tapped (only supported on Android)http: Sends HTTP POST/GET/PUT request when the action button is tapped
Here's an example of what that a notification with actions can look like:
Defining actions
You can define up to three user actions in your notifications, using either of the following methods:
- In the
X-Actionsheader, using a simple comma-separated format - As a JSON array in the
actionskey, when publishing as JSON
Using a header
To define actions using the X-Actions header (or any of its aliases: Actions, Action), use the following format:
=== "Header format (long)"
action=<action1>, label=<label1>, paramN=... [; action=<action2>, label=<label2>, ...]
=== "Header format (short)"
<action1>, <label1>, paramN=... [; <action2>, <label2>, ...]
Multiple actions are separated by a semicolon (;), and key/value pairs are separated by commas (,). Values may be
quoted with double quotes (") or single quotes (') if the value itself contains commas or semicolons.
The action= and label= prefix are optional in all actions, and the url= prefix is optional in the view and
http action. The only limitation of this format is that depending on your language/library, UTF-8 characters may not
work. If they don't, use the JSON array format instead.
As an example, here's how you can create the above notification using this format. Refer to the view action and
http action section for details on the specific actions:
=== "Command line (curl)"
body='{"temperature": 65}' curl \ -d "You left the house. Turn down the A/C?" \ -H "Actions: view, Open portal, https://home.nest.com/, clear=true; \ http, Turn down, https://api.nest.com/, body='$body'" \ ntfy.sh/myhome
=== "ntfy CLI"
body='{"temperature": 65}' ntfy publish \ --actions="view, Open portal, https://home.nest.com/, clear=true; \ http, Turn down, https://api.nest.com/, body='$body'" \ myhome \ "You left the house. Turn down the A/C?"
=== "HTTP" ``` http POST /myhome HTTP/1.1 Host: ntfy.sh Actions: view, Open portal, https://home.nest.com/, clear=true; http, Turn down, https://api.nest.com/, body='{"temperature": 65}'
You left the house. Turn down the A/C?
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/myhome', { method: 'POST', body: 'You left the house. Turn down the A/C?', headers: { 'Actions': 'view, Open portal, https://home.nest.com/, clear=true; http, Turn down, https://api.nest.com/, body=\'{"temperature": 65}\'' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.sh/myhome", strings.NewReader("You left the house. Turn down the A/C?")) req.Header.Set("Actions", "view, Open portal, https://home.nest.com/, clear=true; http, Turn down, https://api.nest.com/, body='{\"temperature\": 65}'") http.DefaultClient.Do(req)
=== "PowerShell"

=== "Python"
python requests.post("https://ntfy.sh/myhome", data="You left the house. Turn down the A/C?", headers={ "Actions": "view, Open portal, https://home.nest.com/, clear=true; http, Turn down, https://api.nest.com/, body='{\"temperature\": 65}'" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/reddit_alerts', false, stream_context_create([ 'http' => [ 'method' => 'POST', 'header' => "Content-Type: text/plain\r\n" . "Actions: view, Open portal, https://home.nest.com/, clear=true; http, Turn down, https://api.nest.com/, body='{\"temperature\": 65}'", 'content' => 'You left the house. Turn down the A/C?' ] ]));
!!! info
ntfy supports UTF-8 in HTTP headers, but not every library or programming language does.
If non-ASCII characters are causing issues for you in the title (i.e. you're seeing ? symbols), you may also encode any header (including actions)
as RFC 2047, e.g. =?UTF-8?B?8J+HqfCfh6o=?= (base64),
or =?UTF-8?Q?=C3=84pfel?= (quoted-printable).
Using a JSON array
Alternatively, the same actions can be defined as JSON array, if the notification is defined as part of the JSON body (see publish as JSON):
=== "Command line (curl)"
curl ntfy.sh \ -d '{ "topic": "myhome", "message": "You left the house. Turn down the A/C?", "actions": [ { "action": "view", "label": "Open portal", "url": "https://home.nest.com/", "clear": true }, { "action": "http", "label": "Turn down", "url": "https://api.nest.com/", "body": "{\"temperature\": 65}" } ] }'

The required/optional fields for each action depend on the type of the action itself. Please refer to
view action, broadcast action, and http action
for details.
Open website/app
Supported on: :material-android: :material-apple: :material-firefox:
The view action opens a website or app when the action button is tapped, e.g. a browser, a Google Maps location, or
even a deep link into Twitter or a show ntfy topic. How exactly the action is handled depends on how Android and your
desktop browser treat the links. Normally it'll just open a link in the browser.
Examples:
http://orhttps://will open your browser (or an app if it registered for a URL)mailto:links will open your mail app, e.g.mailto:phil@example.comgeo:links will open Google Maps, e.g.geo:0,0?q=1600+Amphitheatre+Parkway,+Mountain+View,+CAntfy://links will open ntfy (see ntfy:// links), e.g.ntfy://ntfy.sh/statstwitter://links will open Twitter, e.g.twitter://user?screen_name=..- ...
Here's an example using the X-Actions header:
=== "Command line (curl)"
curl \ -d "Somebody retweeted your tweet." \ -H "Actions: view, Open Twitter, https://twitter.com/binwiederhier/status/1467633927951163392" \ ntfy.sh/myhome

Send Android broadcast
Supported on: :material-android:
The broadcast action sends an Android broadcast intent
when the action button is tapped. This allows integration into automation apps such as MacroDroid
or Tasker, which basically means
you can do everything your phone is capable of. Examples include taking pictures, launching/killing apps, change device
settings, write/read files, etc.
By default, the intent action io.heckel.ntfy.USER_ACTION is broadcast, though this can be changed with the intent parameter (see below).
To send extras, use the extras parameter. Currently, only string extras are supported.
!!! info
If you have no idea what this is, check out the automation apps section, which shows
how to integrate Tasker and MacroDroid with screenshots. The action button integration is identical, except that
you have to use the intent action io.heckel.ntfy.USER_ACTION instead.
Here's an example using the X-Actions header:
=== "Command line (curl)"
curl \ -d "Your wife requested you send a picture of yourself." \ -H "Actions: broadcast, Take picture, extras.cmd=pic, extras.camera=front" \ ntfy.sh/wifey

Send HTTP request
Supported on: :material-android: :material-apple: :material-firefox:
The http action sends a HTTP request when the action button is tapped. You can use this to trigger REST APIs
for whatever systems you have, e.g. opening the garage door, or turning on/off lights.
By default, this action sends a POST request (not GET!), though this can be changed with the method parameter.
The only required parameter is url. Headers can be passed along using the headers parameter.
Here's an example using the X-Actions header:
=== "Command line (curl)"
curl \ -d "Garage door has been open for 15 minutes. Close it?" \ -H "Actions: http, Close door, https://api.mygarage.lan/, method=PUT, headers.Authorization=Bearer zAzsx1sk.., body={\"action\": \"close\"}" \ ntfy.sh/myhome

Click action
Supported on: :material-android: :material-apple: :material-firefox:
You can define which URL to open when a notification is clicked. This may be useful if your notification is related to a Zabbix alert or a transaction that you'd like to provide the deep-link for. Tapping the notification will open the web browser (or the app) and open the website.
To define a click action for the notification, pass a URL as the value of the X-Click header (or its aliase Click).
If you pass a website URL (http:// or https://) the web browser will open. If you pass another URI that can be handled
by another app, the responsible app may open.
Examples:
http://orhttps://will open your browser (or an app if it registered for a URL)mailto:links will open your mail app, e.g.mailto:phil@example.comgeo:links will open Google Maps, e.g.geo:0,0?q=1600+Amphitheatre+Parkway,+Mountain+View,+CAntfy://links will open ntfy (see ntfy:// links), e.g.ntfy://ntfy.sh/statstwitter://links will open Twitter, e.g.twitter://user?screen_name=..- ...
Here's an example that will open Reddit when the notification is clicked:
=== "Command line (curl)"
curl \ -d "New messages on Reddit" \ -H "Click: https://www.reddit.com/message/messages" \ ntfy.sh/reddit_alerts
=== "ntfy CLI"
ntfy publish \ --click="https://www.reddit.com/message/messages" \ reddit_alerts "New messages on Reddit"

Attachments
Supported on: :material-android: :material-firefox:
You can send images and other files to your phone as attachments to a notification. The attachments are then downloaded onto your phone (depending on size and setting automatically), and can be used from the Downloads folder.
There are two different ways to send attachments:
- sending a local file via PUT, e.g. from
~/Flowers/flower.jpgorringtone.mp3 - or by passing an external URL as an attachment, e.g.
https://f-droid.org/F-Droid.apk
Attach local file
To send a file from your computer as an attachment, you can send it as the PUT request body. If a message is greater
than the maximum message size (4,096 bytes) or consists of non UTF-8 characters, the ntfy server will automatically
detect the mime type and size, and send the message as an attachment file. To send smaller text-only messages or files
as attachments, you must pass a filename by passing the X-Filename header or query parameter (or any of its aliases
Filename, File or f).
By default, and how ntfy.sh is configured, the max attachment size is 15 MB (with 100 MB total per visitor). Attachments expire after 3 hours, which typically is plenty of time for the user to download it, or for the Android app to auto-download it. Please also check out the other limits below.
Here's an example showing how to upload an image:
=== "Command line (curl)"
curl \ -T flower.jpg \ -H "Filename: flower.jpg" \ ntfy.sh/flowers
=== "ntfy CLI"
ntfy publish \ --file=flower.jpg \ flowers
=== "HTTP" ``` http PUT /flowers HTTP/1.1 Host: ntfy.sh Filename: flower.jpg Content-Type: 52312
(binary JPEG data)
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/flowers', { method: 'PUT', body: document.getElementById("file").files[0], headers: { 'Filename': 'flower.jpg' } })
=== "Go"
go file, _ := os.Open("flower.jpg") req, _ := http.NewRequest("PUT", "https://ntfy.sh/flowers", file) req.Header.Set("Filename", "flower.jpg") http.DefaultClient.Do(req)
=== "Python"
python requests.put("https://ntfy.sh/flowers", data=open("flower.jpg", 'rb'), headers={ "Filename": "flower.jpg" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/flowers', false, stream_context_create([ 'http' => [ 'method' => 'PUT', 'header' => "Content-Type: application/octet-stream\r\n" . // Does not matter "Filename: flower.jpg", 'content' => file_get_contents('flower.jpg') // Dangerous for large files ] ]));
Here's what that looks like on Android:
Attach file from a URL
Instead of sending a local file to your phone, you can use an external URL to specify where the attachment is hosted. This could be a Dropbox link, a file from social media, or any other publicly available URL. Since the files are externally hosted, the expiration or size limits from above do not apply here.
To attach an external file, simple pass the X-Attach header or query parameter (or any of its aliases Attach or a)
to specify the attachment URL. It can be any type of file.
ntfy will automatically try to derive the file name from the URL (e.g https://example.com/flower.jpg will yield a
filename flower.jpg). To override this filename, you may send the X-Filename header or query parameter (or any of its
aliases Filename, File or f).
Here's an example showing how to attach an APK file:
=== "Command line (curl)"
curl \ -X POST \ -H "Attach: https://f-droid.org/F-Droid.apk" \ ntfy.sh/mydownloads
=== "ntfy CLI"
ntfy publish \ --attach="https://f-droid.org/F-Droid.apk" \ mydownloads
=== "HTTP"

Icons
Supported on: :material-android:
You can include an icon that will appear next to the text of the notification. Simply pass the X-Icon header or query
parameter (or its alias Icon) to specify the URL that the icon is located at. The client will automatically download
the icon (unless it is already cached locally, and less than 24 hours old), and show it in the notification. Icons are
cached locally in the client until the notification is deleted. Only JPEG and PNG images are supported at this time.
Here's an example showing how to include an icon:
=== "Command line (curl)"
curl \ -H "Icon: https://styles.redditmedia.com/t5_32uhe/styles/communityIcon_xnt6chtnr2j21.png" \ -H "Title: Kodi: Resuming Playback" \ -H "Tags: arrow_forward" \ -d "The Wire, S01E01" \ ntfy.sh/tvshows

Here's an example of how it will look on Android:
E-mail notifications
Supported on: :material-android: :material-apple: :material-firefox:
You can forward messages to e-mail by specifying an address in the header. This can be useful for messages that you'd like to persist longer, or to blast-notify yourself on all possible channels.
Usage is easy: Simply pass the X-Email header (or any of its aliases: X-E-mail, Email, E-mail, Mail, or e).
Only one e-mail address is supported.
Since ntfy does not provide auth (yet), the rate limiting is pretty strict (see limitations). In the default configuration, you get 16 e-mails per visitor (IP address) and then after that one per hour. On top of that, your IP address appears in the e-mail body. This is to prevent abuse.
=== "Command line (curl)"
curl \ -H "Email: phil@example.com" \ -H "Tags: warning,skull,backup-host,ssh-login" \ -H "Priority: high" \ -d "Unknown login from 5.31.23.83 to backups.example.com" \ ntfy.sh/alerts curl -H "Email: phil@example.com" -d "You've Got Mail" curl -d "You've Got Mail" "ntfy.sh/alerts?email=phil@example.com"

"Tags: warning,skull,backup-host,ssh-login\r\n" . "Priority: high", 'content' => 'Unknown login from 5.31.23.83 to backups.example.com' ] ]));
Here's what that looks like in Google Mail:
E-mail publishing
Supported on: :material-android: :material-apple: :material-firefox:
You can publish messages to a topic via e-mail, i.e. by sending an email to a specific address. For instance, you can
publish a message to the topic sometopic by sending an e-mail to ntfy-sometopic@ntfy.sh. This is useful for e-mail
based integrations such as for statuspage.io (though these days most services also support webhooks and HTTP calls).
Depending on the server configuration, the e-mail address format can have a prefix to
prevent spam on topics. For ntfy.sh, the prefix is configured to ntfy-, meaning that the general e-mail address
format is:
ntfy-$topic@ntfy.sh
If access control is enabled, and the target topic does not support anonymous writes, e-mail publishing won't work without providing an authorized access token. That will change the format of the e-mail's recipient address to
ntfy-$topic+$token@ntfy.sh
As of today, e-mail publishing only supports adding a message title (the e-mail subject). Tags, priority,
delay and other features are not supported (yet). Here's an example that will publish a message with the
title You've Got Mail to topic sometopic (see ntfy.sh/sometopic):
Phone calls
Supported on: :material-android: :material-apple: :material-firefox:
You can use ntfy to call a phone and read the message out loud using text-to-speech. Similar to email notifications, this can be useful to blast-notify yourself on all possible channels, or to notify people that do not have the ntfy app installed on their phone.
Phone numbers have to be previously verified (via the web app), so this feature is
only available to authenticated users (no anonymous phone calls). To forward a message as a voice call, pass a phone
number in the X-Call header (or its alias: Call), prefixed with a plus sign and the country code, e.g. +12223334444.
You may also simply pass yes as a value to pick the first of your verified phone numbers.
On ntfy.sh, this feature is only supported to ntfy Pro plans.
As of today, the text-to-speed voice used will only support English. If there is demand for other languages, we'll be happy to add support for that. Please open an issue on GitHub.
!!! info You are responsible for the message content, and you must abide by the Twilio Acceptable Use Policy. This particularly means that you must not use this feature to send unsolicited messages, or messages that are illegal or violate the rights of others. Please read the policy for details. Failure to do so may result in your account being suspended or terminated.
Here's how you use it:
=== "Command line (curl)"
curl \ -u :tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2 \ -H "Call: +12223334444" \ -d "Your garage seems to be on fire. You should probably check that out." \ ntfy.sh/alerts

Here's what a phone call from ntfy sounds like:
Audio transcript:
You have a notification from ntfy on topic alerts.
Message: Your garage seems to be on fire. You should probably check that out. End message.
This message was sent by user phil. It will be repeated up to three times.
Authentication
Depending on whether the server is configured to support access control, some topics may be read/write protected so that only users with the correct credentials can subscribe or publish to them. To publish/subscribe to protected topics, you can:
- Use username & password via Basic auth, e.g.
Authorization: Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk - Use access tokens via Bearer/Basic auth, e.g.
Authorization: Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2 - or use either with the
authquery parameter, e.g.?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw
!!! warning When using Basic auth, base64 only encodes username and password. It is not encrypting it. For your self-hosted server, be sure to use HTTPS to avoid eavesdropping and exposing your password.
Username + password
The simplest way to authenticate against a ntfy server is to use Basic auth.
Here's an example with a user testuser and password fakepassword:
=== "Command line (curl)"
curl \ -u testuser:fakepassword \ -d "Look ma, with auth" \ https://ntfy.example.com/mysecrets
=== "ntfy CLI"

python requests.post("https://ntfy.example.com/mysecrets", data="Look ma, with auth", headers={ "Authorization": "Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk" })
=== "PHP"
php-inline file_get_contents('https://ntfy.example.com/mysecrets', false, stream_context_create([ 'http' => [ 'method' => 'POST', // PUT also works 'header' => 'Content-Type: text/plain\r\n' . 'Authorization: Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk', 'content' => 'Look ma, with auth' ] ]));
To generate the Authorization header, use standard base64 to encode the colon-separated <username>:<password>
and prepend the word Basic, i.e. Authorization: Basic base64(<username>:<password>). Here's some pseudo-code that
hopefully explains it better:
username = "testuser"
password = "fakepassword"
authHeader = "Basic " + base64(username + ":" + password) // -> Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk
The following command will generate the appropriate value for you on *nix systems:
echo "Basic $(echo -n 'testuser:fakepassword' | base64)"
Access tokens
In addition to username/password auth, ntfy also provides authentication via access tokens. Access tokens are useful to avoid having to configure your password across multiple publishing/subscribing applications. For instance, you may want to use a dedicated token to publish from your backup host, and one from your home automation system.
You can create access tokens using the ntfy token command, or in the web app in the "Account" section (when logged in).
See access tokens for details.
Once an access token is created, you can use it to authenticate against the ntfy server, e.g. when you publish or
subscribe to topics. Here's an example using Bearer auth,
with the token tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2:
=== "Command line (curl)"
curl \ -H "Authorization: Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2" \ -d "Look ma, with auth" \ https://ntfy.example.com/mysecrets
=== "ntfy CLI"
ntfy publish \ --token tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2 \ ntfy.example.com/mysecrets \ "Look ma, with auth"
=== "HTTP" ``` http POST /mysecrets HTTP/1.1 Host: ntfy.example.com Authorization: Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2
Look ma, with auth
```
=== "JavaScript"
javascript fetch('https://ntfy.example.com/mysecrets', { method: 'POST', // PUT works too body: 'Look ma, with auth', headers: { 'Authorization': 'Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.example.com/mysecrets", strings.NewReader("Look ma, with auth")) req.Header.Set("Authorization", "Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2") http.DefaultClient.Do(req)
=== "PowerShell 7+"
powershell # With PowerShell 7 or greater, we can use the Authentication and Token parameters $Request = @{ Method = "POST" URI = "https://ntfy.example.com/mysecrets" Authorization = "Bearer" Token = "tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2" Body = "Look ma, with auth" } Invoke-RestMethod @Request
=== "PowerShell 5 and earlier"
powershell # In PowerShell 5 and below, we can only send the Bearer token as a string in the Headers $Request = @{ Method = "POST" URI = "https://ntfy.example.com/mysecrets" Headers = @{ Authorization = "Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2" } Body = "Look ma, with auth" } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.example.com/mysecrets", data="Look ma, with auth", headers={ "Authorization": "Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2" })
=== "PHP"
php-inline file_get_contents('https://ntfy.example.com/mysecrets', false, stream_context_create([ 'http' => [ 'method' => 'POST', // PUT also works 'header' => 'Content-Type: text/plain\r\n' . 'Authorization: Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2', 'content' => 'Look ma, with auth' ] ]));
Alternatively, you can use Basic Auth to send the
access token. When sending an empty username, the basic auth password is treated by the ntfy server as an
access token. This is primarily useful to make curl calls easier, e.g. curl -u:tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2 ...:
=== "Command line (curl)"
curl \ -u :tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2 \ -d "Look ma, with auth" \ https://ntfy.example.com/mysecrets
=== "ntfy CLI"
ntfy publish \ --token tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2 \ ntfy.example.com/mysecrets \ "Look ma, with auth"
=== "HTTP" ``` http POST /mysecrets HTTP/1.1 Host: ntfy.example.com Authorization: Basic OnRrX0FnUWRxN21WQm9GRDM3elFWTjI5Umh1TXpOSXoy

=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.example.com/mysecrets", strings.NewReader("Look ma, with auth")) req.Header.Set("Authorization", "Basic OnRrX0FnUWRxN21WQm9GRDM3elFWTjI5Umh1TXpOSXoy") http.DefaultClient.Do(req)
=== "PowerShell"
powershell # Note that PSCredentials *must* have a username, so we fall back to placing the authorization in the Headers as with PowerShell 5 $Request = @{ Method = "POST" URI = "https://ntfy.example.com/mysecrets" Headers = @{ Authorization = "Basic OnRrX0FnUWRxN21WQm9GRDM3elFWTjI5Umh1TXpOSXoy" } Body = "Look ma, with auth" } Invoke-RestMethod @Request

'Authorization: Basic OnRrX0FnUWRxN21WQm9GRDM3elFWTjI5Umh1TXpOSXoy', 'content' => 'Look ma, with auth' ] ]));
Query param
Here's an example using the auth query parameter:
=== "Command line (curl)"
curl \ -d "Look ma, with auth" \ "https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw"
=== "ntfy CLI"
ntfy publish \ -u testuser:fakepassword \ ntfy.example.com/mysecrets \ "Look ma, with auth"
=== "HTTP" ``` http POST /mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw HTTP/1.1 Host: ntfy.example.com
Look ma, with auth
```
=== "JavaScript"
javascript fetch('https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw', { method: 'POST', // PUT works too body: 'Look ma, with auth' })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw", strings.NewReader("Look ma, with auth")) http.DefaultClient.Do(req)
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw" Body = "Look ma, with auth" } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw", data="Look ma, with auth"
=== "PHP"
php-inline file_get_contents('https://ntfy.example.com/mysecrets?auth=QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw', false, stream_context_create([ 'http' => [ 'method' => 'POST', // PUT also works 'header' => 'Content-Type: text/plain', 'content' => 'Look ma, with auth' ] ]));
To generate the value of the auth parameter, encode the value of the Authorization header (see above) using
raw base64 encoding (like base64, but strip any trailing =). Here's some pseudo-code that hopefully
explains it better:
username = "testuser"
password = "fakepassword"
authHeader = "Basic " + base64(username + ":" + password) // -> Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk
authParam = base64_raw(authHeader) // -> QmFzaWMgZEdWemRIVnpaWEk2Wm1GclpYQmhjM04zYjNKaw (no trailing =)
// If your language does not have a function to encode raw base64, simply use normal base64
// and REMOVE TRAILING "=" characters.
The following command will generate the appropriate value for you on *nix systems:
echo -n "Basic `echo -n 'testuser:fakepassword' | base64`" | base64 | tr -d '='
For access tokens, you can use this instead:
echo -n "Bearer faketoken" | base64 | tr -d '='
Advanced features
Message caching
!!! info
If Cache: no is used, messages will only be delivered to connected subscribers, and won't be re-delivered if a
client re-connects. If a subscriber has (temporary) network issues or is reconnecting momentarily,
messages might be missed.
By default, the ntfy server caches messages on disk for 12 hours (see message caching), so all messages you publish are stored server-side for a little while. The reason for this is to overcome temporary client-side network disruptions, but arguably this feature also may raise privacy concerns.
To avoid messages being cached server-side entirely, you can set X-Cache header (or its alias: Cache) to no.
This will make sure that your message is not cached on the server, even if server-side caching is enabled. Messages
are still delivered to connected subscribers, but since= and
poll=1 won't return the message anymore.
=== "Command line (curl)"
curl -H "X-Cache: no" -d "This message won't be stored server-side" ntfy.sh/mytopic curl -H "Cache: no" -d "This message won't be stored server-side" ntfy.sh/mytopic
=== "ntfy CLI"
ntfy publish \ --no-cache \ mytopic "This message won't be stored server-side"
=== "HTTP" ``` http POST /mytopic HTTP/1.1 Host: ntfy.sh Cache: no
This message won't be stored server-side
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/mytopic', { method: 'POST', body: 'This message won't be stored server-side', headers: { 'Cache': 'no' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.sh/mytopic", strings.NewReader("This message won't be stored server-side")) req.Header.Set("Cache", "no") http.DefaultClient.Do(req)
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.sh/mytopic" Headers = @{ Cache="no" } Body = "This message won't be stored server-side" } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/mytopic", data="This message won't be stored server-side", headers={ "Cache": "no" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/mytopic', false, stream_context_create([ 'http' => [ 'method' => 'POST', 'header' => "Content-Type: text/plain\r\n" . "Cache: no", 'content' => 'This message won't be stored server-side' ] ]));
Disable Firebase
!!! info
If Firebase: no is used and instant delivery isn't enabled in the Android
app (Google Play variant only), message delivery will be significantly delayed (up to 15 minutes). To overcome
this delay, simply enable instant delivery.
The ntfy server can be configured to use Firebase Cloud Messaging (FCM) (see Firebase config) for message delivery on Android (to minimize the app's battery footprint). The ntfy.sh server is configured this way, meaning that all messages published to ntfy.sh are also published to corresponding FCM topics.
If you'd like to avoid forwarding messages to Firebase, you can set the X-Firebase header (or its alias: Firebase)
to no. This will instruct the server not to forward messages to Firebase.
=== "Command line (curl)"
curl -H "X-Firebase: no" -d "This message won't be forwarded to FCM" ntfy.sh/mytopic curl -H "Firebase: no" -d "This message won't be forwarded to FCM" ntfy.sh/mytopic
=== "ntfy CLI"
ntfy publish \ --no-firebase \ mytopic "This message won't be forwarded to FCM"
=== "HTTP" ``` http POST /mytopic HTTP/1.1 Host: ntfy.sh Firebase: no
This message won't be forwarded to FCM
```
=== "JavaScript"
javascript fetch('https://ntfy.sh/mytopic', { method: 'POST', body: 'This message won't be forwarded to FCM', headers: { 'Firebase': 'no' } })
=== "Go"
go req, _ := http.NewRequest("POST", "https://ntfy.sh/mytopic", strings.NewReader("This message won't be forwarded to FCM")) req.Header.Set("Firebase", "no") http.DefaultClient.Do(req)
=== "PowerShell"
powershell $Request = @{ Method = "POST" URI = "https://ntfy.sh/mytopic" Headers = @{ Firebase="no" } Body = "This message won't be forwarded to FCM" } Invoke-RestMethod @Request
=== "Python"
python requests.post("https://ntfy.sh/mytopic", data="This message won't be forwarded to FCM", headers={ "Firebase": "no" })
=== "PHP"
php-inline file_get_contents('https://ntfy.sh/mytopic', false, stream_context_create([ 'http' => [ 'method' => 'POST', 'header' => "Content-Type: text/plain\r\n" . "Firebase: no", 'content' => 'This message won't be stored server-side' ] ]));
UnifiedPush
!!! info This setting is not relevant to users, only to app developers and people interested in UnifiedPush.
UnifiedPush is a standard for receiving push notifications without using the Google-owned Firebase Cloud Messaging (FCM) service. It puts push notifications in the control of the user. ntfy can act as a UnifiedPush distributor, forwarding messages to apps that support it.
When publishing messages to a topic, apps using ntfy as a UnifiedPush distributor can set the X-UnifiedPush header or query
parameter (or any of its aliases unifiedpush or up) to 1 to disable Firebase. As of today, this
option is mostly equivalent to Firebase: no, but was introduced to allow future flexibility. The flag additionally
enables auto-detection of the message encoding. If the message is binary, it'll be encoded as base64.
Matrix Gateway
The ntfy server implements a Matrix Push Gateway (in combination with UnifiedPush as the Provider Push Protocol). This makes it easier to integrate with self-hosted Matrix servers (such as synapse), since you don't have to set up a separate push proxy (such as common-proxies).
In short, ntfy accepts Matrix messages on the /_matrix/push/v1/notify endpoint (see Push Gateway API),
and forwards them to the ntfy topic defined in the pushkey of the message. The message will then be forwarded to the
ntfy Android app, and passed on to the Matrix client there.
There is a nice diagram in the Push Gateway docs. In this diagram, the ntfy server plays the role of the Push Gateway, as well as the Push Provider. UnifiedPush is the Provider Push Protocol.
!!! info This is not a generic Matrix Push Gateway. It only works in combination with UnifiedPush and ntfy.
Public topics
Obviously all topics on ntfy.sh are public, but there are a few designated topics that are used in examples, and topics that you can use to try out what authentication and access control looks like.
| Topic | User | Permissions | Description |
|---|---|---|---|
| announcements | * (unauthenticated) |
Read-only for everyone | Release announcements and such |
| stats | * (unauthenticated) |
Read-only for everyone | Daily statistics about ntfy.sh usage |
Limitations
There are a few limitations to the API to prevent abuse and to keep the server healthy. Almost all of these settings are configurable via the server side rate limiting settings. Most of these limits you won't run into, but just in case, let's list them all:
| Limit | Description |
|---|---|
| Message length | Each message can be up to 4,096 bytes long. Longer messages are treated as attachments. |
| Requests | By default, the server is configured to allow 60 requests per visitor at once, and then refills the your allowed requests bucket at a rate of one request per 5 seconds. |
| Daily messages | By default, the number of messages is governed by the request limits. This can be overridden. On ntfy.sh, the daily message limit is 250. |
| E-mails | By default, the server is configured to allow sending 16 e-mails per visitor at once, and then refills the your allowed e-mail bucket at a rate of one per hour. On ntfy.sh, the daily limit is 5. |
| Phone calls | By default, the server does not allow any phone calls, except for users with a tier that has a call limit. |
| Subscription limit | By default, the server allows each visitor to keep 30 connections to the server open. |
| Attachment size limit | By default, the server allows attachments up to 15 MB in size, up to 100 MB in total per visitor and up to 5 GB across all visitors. On ntfy.sh, the attachment size limit is 2 MB, and the per-visitor total is 20 MB. |
| Attachment expiry | By default, the server deletes attachments after 3 hours and thereby frees up space from the total visitor attachment limit. |
| Attachment bandwidth | By default, the server allows 500 MB of GET/PUT/POST traffic for attachments per visitor in a 24 hour period. Traffic exceeding that is rejected. On ntfy.sh, the daily bandwidth limit is 200 MB. |
| Total number of topics | By default, the server is configured to allow 15,000 topics. The ntfy.sh server has higher limits though. |
These limits can be changed on a per-user basis using tiers. If payments are enabled, a user tier can be changed by purchasing a higher tier. ntfy.sh offers multiple paid tiers, which allows for much hier limits than the ones listed above.
List of all parameters
The following is a list of all parameters that can be passed when publishing a message. Parameter names are case-insensitive when used in HTTP headers, and must be lowercase when used as query parameters in the URL. They are listed in the table in their canonical form.
!!! info
ntfy supports UTF-8 in HTTP headers, but not every library or programming language does.
If non-ASCII characters are causing issues for you in the title (i.e. you're seeing ? symbols), you may also encode any
header as RFC 2047, e.g. =?UTF-8?B?8J+HqfCfh6o=?= (base64),
or =?UTF-8?Q?=C3=84pfel?= (quoted-printable).
