Transports

Notifications can be sent to users via multiple mediums. By default, the global email configuration will be used.

Generic Webhook

This will send a POST request to the given URL with the following contents:

{
    "body": "body of the notification message",
    "severity": "severity level as configured in the trigger",
    "user_email": "user's email",
    "user_username": "user's username",
}

The Content-Type header is set to text/json.

Slack Webhook

This sends a request using the Slack-specific format. This is also compatible with Discord's webhooks by appending /slack to the Discord webhook URL.
