Getting started

ntfy lets you send push notifications to your phone or desktop via scripts from any computer, using simple HTTP PUT or POST requests. I use it to notify myself when scripts fail, or long-running commands complete.

Step 1: Get the app

<a href="https://play.google.com/store/apps/details?id=io.heckel.ntfy"></a> <a href="https://f-droid.org/en/packages/io.heckel.ntfy/"></a> <a href="https://apps.apple.com/us/app/ntfy/id1625396347"></a>

To receive notifications on your phone, install the app, either via Google Play, App Store or F-Droid. Once installed, open it and subscribe to a topic of your choosing. Topics don't have to explicitly be created, so just pick a name and use it later when you publish a message. Note that topic names are public, so it's wise to choose something that cannot be guessed easily.

For this guide, we'll just use mytopic as our topic name:

That's it. After you tap "Subscribe", the app is listening for new messages on that topic.

Step 2: Send a message

Now let's send a message to our topic. It's easy in every language, since we're just using HTTP PUT/POST, or with the ntfy CLI. The message is in the request body. 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 😀"))

=== "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 😀' ] ]));

This will create a notification that looks like this:

That's it. You're all set. Go play and read the rest of the docs. I highly recommend reading at least the page on publishing messages, as well as the detailed page on the Android/iOS app.
