Epic Links API (ULTIMATE)

Introduced in GitLab 11.8.

Manages parent-child epic relationships.

Every API call to epic_links must be authenticated.

If a user is not a member of a group and the group is private, a GET request on that group will result to a 404 status code.

Multi-level Epics are available only in GitLab Ultimate/Gold. If the Multi-level Epics feature is not available, a 403 status code will be returned.
