Configure Git Webhooks
You can configure Ossum to deliver a JSON payload to a URL you specify based on different events in your repository. Webhooks are configured from your Repository Settings. To add a webhook click on the New URL button, specify the URL to send the hook output to, and the events you wish to receive. You can add multiple webhooks. Be sure to click Save when you are done.
The first two events are the most common/likely for you to use. The Reference Updated event is sent after a push, when a new branch/tag is created and when a merge request is merged to a branch. The Patchset Created event is sent when a new merge request is created or when a the merge request is updated with new changes. All of the other events are fairly self-explanatory and related to different actions that can be taken on a merge request.
