# Epics API (deprecated)
DETAILS:
**Tier:** Premium, Ultimate
**Offering:** GitLab.com, Self-managed, GitLab Dedicated
WARNING:
The Epics REST API was [deprecated](https://gitlab.com/gitlab-org/gitlab/-/issues/460668) 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](../user/group/epics/epic_work_items.md), use the
[Work Items API](https://handbook.gitlab.com/handbook/engineering/architecture/design-documents/work_items/) instead. For more information, see the [guide how to migrate your existing APIs](../api/graphql/epic_work_items_api_migration_guide.md).
This change is a breaking change.
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](epic_issues.md) allows you to interact with issues associated with an epic.
## Milestone dates integration
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](rest/index.md#pagination).
WARNING:
In [GitLab 12.6](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/20354) and later,
the `reference` attribute in responses is deprecated in favor of `references`.
NOTE:
`references.relative` is relative to the group that the epic is being requested from. When an epic
is fetched from its origin group, the `relative` format is the same as the `short` format.
When an epic is requested across groups, the `relative` format is expected to be the same as the `full` format.
## List epics for a group
Gets all epics of the requested group and its subgroups.

## New epic
Creates a new epic.
NOTE:
Starting with GitLab [11.3](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/6448), `start_date` and `end_date` should no longer be assigned
directly, as they now represent composite values. You can configure it via the `*_is_fixed` and
`*_fixed` fields instead.

## Delete epic
- [Changed](https://gitlab.com/gitlab-org/gitlab/-/issues/452189) in GitLab 16.11. In GitLab 16.10 and earlier, if you delete an epic, all its child epics and their descendants are deleted as well. If needed, you can remove child epics from the parent epic before you delete it.
