Epics API

Version history

Every API call to epic 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.

If epics feature is not available a 403 status code is returned.

Epic issues API

The epic issues API allows you to interact with issues associated with an epic.

Milestone dates integration

Introduced in GitLab 11.3.

Because start date and due date can be dynamically sourced from related issue milestones, additional fields are shown when user has edit permission. These include two boolean fields start_date_is_fixed and due_date_is_fixed, and four date fields start_date_fixed, start_date_from_inherited_source, due_date_fixed and due_date_from_inherited_source.

  • end_date has been deprecated in favor of due_date.
  • start_date_from_milestones has been deprecated in favor of start_date_from_inherited_source
  • due_date_from_milestones has been deprecated in favor of due_date_from_inherited_source

Epics pagination

By default, GET requests return 20 results at a time because the API results are paginated.

Read more on pagination.

caution> reference attribute in response is deprecated in favour of references. > Introduced in GitLab 12.6
note> references.relative is relative to the group that the epic is being requested. When epic is fetched from its origin group > relative format would be the same as short format and when requested cross groups it is expected to be the same as full format.
