# Epics API **[ULTIMATE]**

Every API call to epic must be authenticated.

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

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

## Epic issues API

The [epic issues API](epic_issues.md) allows you to interact with issues associated with an epic.

# Milestone dates integration

> [Introduced][ee-6448] in GitLab 11.3.

Since start date and due date can be dynamically sourced from related issue milestones, when user has edit permission, additional fields will be shown. These include two boolean fields `start_date_is_fixed` and `due_date_is_fixed`, and four date fields `start_date_fixed`, `start_date_from_milestones`, `due_date_fixed` and `due_date_from_milestones`.

`end_date` has been deprecated in favor of `due_date`.

## Epics pagination

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

Read more on [pagination](README.md#pagination).

## List epics for a group

Gets all epics of the requested group and its subgroups.
