events-backend-module-gitlab

Welcome to the events-backend-module-gitlab backend module!

This package is a module for the events-backend backend plugin and extends the event system with an GitlabEventRouter.

The event router will subscribe to the topic gitlab and route the events to more concrete topics based on the value of the provided $.event_name payload field.

Examples:

$.event_name	topic
push	gitlab.push
merge_request	gitlab.merge_request

Please find all possible webhook event types at the official documentation.
