## Click action
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.
## User actions
You can add action buttons to notifications to allow yourself to react to a notification directly. This is incredibly
useful and has countless applications. As of today, the following actions are supported:
Here's an example that will open Reddit when the notification is clicked:
* [`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
* [`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>
![notification with actions](static/img/notification-with-tags.png){ width=500 }
<figcaption>XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</figcaption>

## User actions

| `action` | ✔️ | *view, broadcast, or http* | `view` | Action type |
| `label` | ✔️ | *string* | `Turn on light` | Label of the action button in the notification |
### Open website/app
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.
### Send Android broadcast
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.
### Send HTTP request
The `http` action sends a HTTP POST/GET/PUT 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.
