Webhooks
========
Webhooks are useful to perform actions with external applications.
- Webhooks can be used to create a task by calling a simple URL (You can also do that with the API)
- An external URL can be called automatically when an event occurs in Kanboard (task creation, comment updated, etc)
How to write a web hook receiver?
---------------------------------
All internal events of Kanboard can be sent to an external URL.
- The web hook URL has to be defined in **Settings > Webhooks > Webhook URL**.
- When an event is triggered Kanboard calls the pre-defined URL automatically
- The data are encoded in JSON format and sent with a POST HTTP request
- The web hook token is also sent as a query string parameter, so you can check if the request really comes from Kanboard.
- **Your custom URL must answer in less than 1 second**, those requests are synchronous (PHP limitation) and that can slow down the user interface if your script is too slow!
### List of supported events

All event payloads are in the following format:
```json
{
"event_name": "model.event_name",
"event_data": {
"key1": "value1",
"key2": "value2",
...
}
}
```
The `event_data` values are not necessary normalized across events.
