# Epic Links API **(ULTIMATE)**
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/9188) in GitLab 11.8.
|
|
|
|
Manages parent-child [epic relationships](../user/group/epics/manage_epics.md#multi-level-child-epics).
|
|
|
|
Every API call to `epic_links` must be authenticated.
|
|
|
|
If a user is not a member of a private group, a `GET` request on that
|
|
group results in a `404` status code.
|
|
|
|
Multi-level Epics are available only in GitLab [Ultimate](https://about.gitlab.com/pricing/).
|
|
If the Multi-level Epics feature is not available, a `403` status code is returned.
|
|
|
|
## List epics related to a given epic
|
|
|
|
Gets all child epics of an epic.
