## FilterBox Webhook Functionality Guide

Starting from version 2.0.0, Filter Box has added Webhook functionality, allowing you to create rules to send notification content to specified URLs.

Note: Notification content may contain private information. Please ensure you choose a server you trust.

### Custom Content

- Request method: Currently supports `GET` and `POST`
- You can customize URL, body, and headers.

The custom URL and body support various notification attribute fields. For a complete list of supported fields, check the "Debug Info" option in any of your 20 most recent notifications in the notification list.

Here are some commonly used fields:

- `{android.title}` Notification title
- `{android.text}` Notification content
- `{filterbox.field.APP_NAME}` App name
- `{filterbox.field.PACKAGE_NAME}` App package name
- `{filterbox.field.WHEN}` Notification send time

URL syntax example:
```
https://example.com/notification?title={android.title}&message={android.text}&app={filterbox.field.APP_NAME}
```
Body syntax example:
```
{
  "title": "{android.title}",
  "text": "{android.text}",
  "app": "{filterbox.field.PACKAGE_NAME}",
  "some_other_field1": "some other field here",
  "some_other_field2": "some other field here",
  "some_other_field3": "some other field here"
}
```
When using JSON format for the body, it's recommended to set the header as `Content-Type: application/json`

If you have questions or feature requests, please contact us using the feedback function within the App.
