Linked epics API

Tier: Ultimate Offering: GitLab.com, Self-managed, GitLab Dedicated

History

Introduced in GitLab 14.9 with a flag named related_epics_widget. Enabled by default.
Feature flag related_epics_widget removed in GitLab 15.0.

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. This change is a breaking change.

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