Epic Issues API

Tier: Premium, Ultimate Offering: GitLab.com, Self-managed, GitLab Dedicated
caution
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. For more information, see the guide how to migrate your existing APIs. This change is a breaking change.

Every API call to the epic issues API endpoint 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 Ultimate. If the Epics feature is not available, a 403 status code is returned.

Epic Issues pagination

API results are paginated. Requests that return multiple issues default to returning 20 results at a time.

List issues for an epic

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

GET /groups/:id/epics/:epic_iid/issues
Attribute Type Required Description
id integer/string yes The ID or URL-encoded path of the group
epic_iid integer/string yes The internal ID of the epic. 
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/groups/1/epics/5/issues/"
