Linked epics API

Tier: Ultimate Offering: GitLab.com, Self-managed, GitLab Dedicated
History
caution
The Epics REST API was deprecated in GitLab 17.0 and is planned for removal in v5 of the API. In GitLab 17.4 or later, if your administrator enabled the new look for epics, use the Work Items API instead. For more information, see the guide how to migrate your existing APIs. This change is a breaking change.

If the Related Epics feature is not available in your GitLab plan, a 403 status code is returned.
