# 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.
```plaintext

## Assign a child epic
Creates an association between two epics, designating one as the parent epic and the other as the child epic. A parent epic can have multiple child epics. If the new child epic already belonged to another epic, it is unassigned from that previous parent.
