--- title: Transports --- Notifications can be sent to users via multiple mediums. By default, the [global email configuration](../installation/docker-compose#email-configuration-optional-but-recommended) will be used. ## Generic Webhook This will send a POST request to the given URL with the following contents: ```json { "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`. Starting in 2021.9, you can also select a Notification mapping. This allows you to freely configure the request's payload. For example: ```python return { "foo": context['notification'].body, } ``` ## 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.
