Webhook

A webhook is an action configured on an event to communicate with an external system. It is not a separate event type for POST /event/fire.

Configure the target integration and attach the action to the relevant event. See Setting up an action and Events and Actions. The destination URL, authentication, request mapping, and response handling depend on that integration's configuration.

Use Firing an Event to submit a supported event. The event submission response describes the trigger execution; it does not define the payload your webhook endpoint will receive.
