Merge Trains API (PREMIUM)

• Introduced in GitLab 12.9.
• Using this API you can consume Merge Train entries.

Every API call to merge trains must be authenticated with Developer or higher permissions.

If a user is not a member of a project and the project is private, a GET request on that project returns a 404 status code.

If Merge Trains is not available for the project, a 403 status code is returned.

Merge Trains API pagination

By default, GET requests return 20 results at a time because the API results are paginated.

Read more on pagination.
