# Publishing
|
||
Publishing messages can be done via HTTP PUT/POST or via the [ntfy CLI](install.md). 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](subscribe/phone.md) installed on your phone, this will create a notification that looks like this:
|
||
|
||
<figure markdown>
|
||
{ width=500 }
|
||
<figcaption>Android notification</figcaption>
|
||
</figure>
|
||
|
||
There are more features related to publishing messages: You can set a [notification priority](#message-priority),
|
||
a [title](#message-title), and [tag messages](#tags-emojis) 🥳 🎉. 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 \
|

## 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)"
|

```

!!! info
|
||
ntfy supports UTF-8 in HTTP headers, but [not every library or programming language does](https://www.jmix.io/blog/utf-8-in-http-headers/).
|
||
If non-ASCII characters are causing issues for you in the title (i.e. you're seeing `?` symbols), you may also encode the `X-Title` or `X-Message`
|
||
header as [RFC 2047](https://datatracker.ietf.org/doc/html/rfc2047#section-2), e.g. `=?UTF-8?B?8J+HqfCfh6o=?=` ([base64](https://en.wikipedia.org/wiki/Base64)),
|
||
or `=?UTF-8?Q?=C3=84pfel?=` ([quoted-printable](https://en.wikipedia.org/wiki/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](subscribe/phone.md)).
|
||
|
||
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
|

```

## 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](emojis.md), 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](emojis.md) to figure out what tags can be converted to emojis.
|
||
Here's an **excerpt of emojis** I've found very useful in alert messages:
|
||
|
||
<table class="remove-md-box"><tr>
|
||
<td>
|
||
<table><thead><tr><th>Tag</th><th>Emoji</th></tr></thead><tbody>
|
||
<tr><td><code>+1</code></td><td>👍</td></tr>

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`.

!!! info
|
||
ntfy supports UTF-8 in HTTP headers, but [not every library or programming language does](https://www.jmix.io/blog/utf-8-in-http-headers/).
|
||
If non-ASCII characters are causing issues for you in the title (i.e. you're seeing `?` symbols), you may also encode the individual tags
|
||
as [RFC 2047](https://datatracker.ietf.org/doc/html/rfc2047#section-2), e.g. `tag1,=?UTF-8?B?8J+HqfCfh6o=?=` ([base64](https://en.wikipedia.org/wiki/Base64)),
|
||
or `=?UTF-8?Q?=C3=84pfel?=,tag2` ([quoted-printable](https://en.wikipedia.org/wiki/Quoted-printable)).
|
||
|
||
## 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](https://github.com/olebedev/when)).
|
||
|
||
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](https://github.com/binwiederhier/ntfy/issues) if you'd like to change
|
||
these limits).
|
||
|
||
For the purposes of [message caching](config.md#message-cache), 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](#message-caching) is not possible in combination with this feature.

## 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](https://en.wikipedia.org/wiki/Webhook), or if your client has limited HTTP support (e.g.
|
||
like the [MacroDroid](https://play.google.com/store/apps/details?id=com.arlosoft.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](#list-of-all-parameters) 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](#message-priority), the [message title](#message-title), and [tags](#tags-emojis) as well.
|
||
For a full list of possible parameters, check the list of [supported parameters and headers](#list-of-all-parameters).
|
||
|
||
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
|
||

|
||
```
|
||
|
||
=== "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](https://jellyfin.org/), [overseerr](https://overseerr.dev/)),
|
||
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",
|

## 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`](#open-websiteapp): Opens a website or app when the action button is tapped
|
||
* [`broadcast`](#send-android-broadcast): Sends an [Android broadcast](https://developer.android.com/guide/components/broadcasts) intent
|
||
when the action button is tapped (only supported on Android)
|
||
* [`http`](#send-http-request): 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:
|
||
|
||
<figure markdown>
|
||
{ width=500 }
|
||
<figcaption>Notification with two user actions</figcaption>
|
||
</figure>
|
||
|
||
### Defining actions
|
||
You can define **up to three user actions** in your notifications, using either of the following methods:
|
||
|
||
* In the [`X-Actions` header](#using-a-header), using a simple comma-separated format
|
||
* As a [JSON array](#using-a-json-array) in the `actions` key, when [publishing as JSON](#publish-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](#using-a-json-array) instead.
|
||
|
||
As an example, here's how you can create the above notification using this format. Refer to the [`view` action](#open-websiteapp) and
|
||
[`http` action](#send-http-request) 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; \

The required/optional fields for each action depend on the type of the action itself. Please refer to
|
||
[`view` action](#open-websiteapp), [`broadcast` action](#send-android-broadcast), and [`http` action](#send-http-request)
|
||
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://` or `https://` 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.com`
|
||
* `geo:` links will open Google Maps, e.g. `geo:0,0?q=1600+Amphitheatre+Parkway,+Mountain+View,+CA`
|
||
* `ntfy://` links will open ntfy (see [ntfy:// links](subscribe/phone.md#ntfy-links)), e.g. `ntfy://ntfy.sh/stats`
|
||
* `twitter://` links will open Twitter, e.g. `twitter://user?screen_name=..`
|
||
* ...

|
||

### Send Android broadcast
|
||
_Supported on:_ :material-android:
|
||
|
||
The `broadcast` action **sends an [Android broadcast](https://developer.android.com/guide/components/broadcasts) intent
|
||
when the action button is tapped**. This allows integration into automation apps such as [MacroDroid](https://play.google.com/store/apps/details?id=com.arlosoft.macrodroid)
|
||
or [Tasker](https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm), 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](subscribe/phone.md#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.
|
||
|
||

|
||
|
||
### 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](#using-a-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\"}" \

|
||
## 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://` or `https://` 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.com`
|
||
* `geo:` links will open Google Maps, e.g. `geo:0,0?q=1600+Amphitheatre+Parkway,+Mountain+View,+CA`
|
||
* `ntfy://` links will open ntfy (see [ntfy:// links](subscribe/phone.md#ntfy-links)), e.g. `ntfy://ntfy.sh/stats`
|
||
* `twitter://` links will open Twitter, e.g. `twitter://user?screen_name=..`
|
||
* ...
|
||
|
||
Here's an example that will open Reddit when the notification is clicked:

|
||
|
||
## 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](#attach-local-file) via PUT, e.g. from `~/Flowers/flower.jpg` or `ringtone.mp3`
|
||
* or by [passing an external URL](#attach-file-from-a-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](#limitations).
|
||
|
||
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"
|
||
```
|
||

|
||
--file=flower.jpg \
|
||
flowers
|
||
```

||
=== "HTTP"

|
||
})
|
||
```
|
||
|
||

||
``` go
|
||
file, _ := os.Open("flower.jpg")
|
||

|
||

|
||
http.DefaultClient.Do(req)
|
||
```
|
||
|
||

|
||
``` python
|
||

|
||
data=open("flower.jpg", 'rb'),
|
||
headers={ "Filename": "flower.jpg" })

|
||
'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:

<figure markdown>
|
||
{ width=500 }
|
||
<figcaption>Image attachment sent from a local file</figcaption>
|
||
</figure>
|
||
|
||
### 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`).
|
||

||

## 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:
|
||
|

## 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](#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.
|
||
|

## 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](config.md#e-mail-publishing), 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-$topic@ntfy.sh
|
||
```
|
||
|
||
If [access control](config.md#access-control) is enabled, and the target topic does not support anonymous writes, e-mail publishing won't work without providing an authorized access token. That will change the format of the e-mail's recipient address to
|
||
```
|
||
ntfy-$topic+$token@ntfy.sh
|
||
```
|
||
|
||
As of today, e-mail publishing only supports adding a [message title](#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](https://ntfy.sh/sometopic)):

||

||
## Authentication
|
||
Depending on whether the server is configured to support [access control](config.md#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](#username-password) via Basic auth, e.g. `Authorization: Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk`
|
||
* Use [access tokens](#bearer-auth) via Bearer/Basic auth, e.g. `Authorization: Bearer tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2`
|
||
* or use either with the [`auth` query parameter](#query-param), 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](https://en.wikipedia.org/wiki/Basic_access_authentication).
|
||
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"
|
||
```
|
||
ntfy publish \
|
||
-u testuser:fakepassword \
|
||
ntfy.example.com/mysecrets \
|
||
"Look ma, with auth"
|
||
```
|
||
|
||
=== "HTTP"
|
||
``` http
|
||
POST /mysecrets HTTP/1.1
|
||
Host: ntfy.example.com
|
||
Authorization: Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk
|
||
|
||
Look ma, with auth
|
||
```
|
||
|
||
=== "JavaScript"
|
||
``` javascript
|
||
fetch('https://ntfy.example.com/mysecrets', {
|
||
method: 'POST', // PUT works too
|
||
body: 'Look ma, with auth',
|
||
headers: {
|
||
'Authorization': 'Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk'
|
||
}
|
||
})
|
||
```
|
||
|
||
=== "Go"
|
||
``` go
|
||
req, _ := http.NewRequest("POST", "https://ntfy.example.com/mysecrets",
|
||
strings.NewReader("Look ma, with auth"))
|
||
req.Header.Set("Authorization", "Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk")
|
||
http.DefaultClient.Do(req)
|
||
```
|
||
|
||
=== "PowerShell 7+"
|
||
``` powershell
|
||
# Get the credentials from the user
|
||
$Credential = Get-Credential testuser
|
||
|
||
# Alternatively, create a PSCredential object with the password from scratch
|
||
$Credential = [PSCredential]::new("testuser", (ConvertTo-SecureString "password" -AsPlainText -Force))
|
||
|
||
# Note that the Authentication parameter requires PowerShell 7 or later
|
||
$Request = @{
|
||
Method = "POST"
|
||
URI = "https://ntfy.example.com/mysecrets"
|
||
Authentication = "Basic"
|
||
Credential = $Credential
|
||
Body = "Look ma, with auth"
|
||
}
|
||

|
||
```
|
||

|
||
# With PowerShell 5 or earlier, we need to create the base64 username:password string ourselves
|
||
$CredentialString = "$($Credential.Username):$($Credential.GetNetworkCredential().Password)"
|
||

|
||

|
||

|
||
Headers = @{ Authorization = "Basic $EncodedCredential"}
|
||
Body = "Look ma, with auth"
|
||
}
|
||
Invoke-RestMethod @Request
|
||
```
|
||
|
||
=== "Python"
|
||
``` 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](config.md#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](https://swagger.io/docs/specification/authentication/bearer-authentication/),
|
||
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 \

|
||
'content' => 'Look ma, with auth'
|
||
]
|
||
]));
|
||
```
|
||
|
||
Alternatively, you can use [Basic Auth](https://en.wikipedia.org/wiki/Basic_access_authentication) 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 \

||
``` 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 '='
|
||
```
|
||
|
||
## 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](config.md#message-cache)), 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=`](subscribe/api.md#fetch-cached-messages) and
|
||
[`poll=1`](subscribe/api.md#poll-for-messages) won't return the message anymore.
|
||
|
||

|
||
```

||

|
||
'content' => 'This message won't be stored server-side'
|
||
]
|
||
]));
|
||
```
|
||
|
||
### Disable Firebase
|
||
!!! info
|
||
If `Firebase: no` is used and [instant delivery](subscribe/phone.md#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)](https://firebase.google.com/docs/cloud-messaging)
|
||
(see [Firebase config](config.md#firebase-fcm)) 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"

|
||

|
||
'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](https://unifiedpush.org).
|
||
|
||
[UnifiedPush](https://unifiedpush.org) is a standard for receiving push notifications without using the Google-owned
|
||
[Firebase Cloud Messaging (FCM)](https://firebase.google.com/docs/cloud-messaging) 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](#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](https://spec.matrix.org/v1.2/push-gateway-api/) (in combination with
|
||
[UnifiedPush](https://unifiedpush.org) as the [Provider Push Protocol](https://unifiedpush.org/developers/gateway/)). This makes it easier to integrate
|
||
with self-hosted [Matrix](https://matrix.org/) servers (such as [synapse](https://github.com/matrix-org/synapse)), since
|
||
you don't have to set up a separate push proxy (such as [common-proxies](https://github.com/UnifiedPush/common-proxies)).
|
||
|
||
In short, ntfy accepts Matrix messages on the `/_matrix/push/v1/notify` endpoint (see [Push Gateway API](https://spec.matrix.org/v1.2/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](https://spec.matrix.org/v1.2/push-gateway-api/). 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](#authentication) looks like.
|
||
|
||
| Topic | User | Permissions | Description |
|
||
|------------------------------------------------|-----------------------------------|------------------------------------------------------|--------------------------------------|
|
||
| [announcements](https://ntfy.sh/announcements) | `*` (unauthenticated) | Read-only for everyone | Release announcements and such |
|
||
| [stats](https://ntfy.sh/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](config.md#rate-limiting). 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](#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. |
|
||
| **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](config.md#tiers). If [payments](config.md#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](https://www.jmix.io/blog/utf-8-in-http-headers/).
|
||
If non-ASCII characters are causing issues for you in the title (i.e. you're seeing `?` symbols), you may also encode the `X-Title` or `X-Message`
|
||
header as [RFC 2047](https://datatracker.ietf.org/doc/html/rfc2047#section-2), e.g. `=?UTF-8?B?8J+HqfCfh6o=?=` ([base64](https://en.wikipedia.org/wiki/Base64)),
|
||
or `=?UTF-8?Q?=C3=84pfel?=` ([quoted-printable](https://en.wikipedia.org/wiki/Quoted-printable)).
|
||
|
||
| Parameter | Aliases | Description |
|
||
|-----------------|--------------------------------------------|-----------------------------------------------------------------------------------------------|
|
||
| `X-Message` | `Message`, `m` | Main body of the message as shown in the notification |
|
||
| `X-Title` | `Title`, `t` | [Message title](#message-title) |
|
||
| `X-Priority` | `Priority`, `prio`, `p` | [Message priority](#message-priority) |
|
||
| `X-Tags` | `Tags`, `Tag`, `ta` | [Tags and emojis](#tags-emojis) |
|
||
| `X-Delay` | `Delay`, `X-At`, `At`, `X-In`, `In` | Timestamp or duration for [delayed delivery](#scheduled-delivery) |
|
||
| `X-Actions` | `Actions`, `Action` | JSON array or short format of [user actions](#action-buttons) |
|
||
| `X-Click` | `Click` | URL to open when [notification is clicked](#click-action) |
|
||
| `X-Attach` | `Attach`, `a` | URL to send as an [attachment](#attachments), as an alternative to PUT/POST-ing an attachment |
|
||
| `X-Icon` | `Icon` | URL to use as notification [icon](#icons) |
|
||
| `X-Filename` | `Filename`, `file`, `f` | Optional [attachment](#attachments) filename, as it appears in the client |
|
||
| `X-Email` | `X-E-Mail`, `Email`, `E-Mail`, `mail`, `e` | E-mail address for [e-mail notifications](#e-mail-notifications) |
|
||
| `X-Cache` | `Cache` | Allows disabling [message caching](#message-caching) |
|
||
| `X-Firebase` | `Firebase` | Allows disabling [sending to Firebase](#disable-firebase) |
|
||

|
||
| `X-Poll-ID` | `Poll-ID` | Internal parameter, used for [iOS push notifications](config.md#ios-instant-notifications) |
|
||
| `Authorization` | - | If supported by the server, you can [login to access](#authentication) protected topics |
|
