# Epic Issues API **(PREMIUM)**

Every API call to epic_issues must be authenticated.

If a user is not a member of a group and the group is private, a `GET` request on that group
results in a `404` status code.

Epics are available only in GitLab [Premium and higher](https://about.gitlab.com/pricing/).
If the Epics feature is not available, a `403` status code is returned.

## List issues for an epic

Gets all issues that are assigned to an epic and the authenticated user has access to.
