# Issues API **(FREE)**

Interact with [GitLab Issues](../user/project/issues/index.md) using the REST API.

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

## Issues 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:
The `reference` attribute in responses is deprecated in favor of `references`.
[Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/20354) in GitLab 12.6.

NOTE:
The `references.relative` attribute is relative to the group or project of the issue being requested.
When an issue is fetched from its project, the `relative` format is the same as the `short` format.
When requested across groups or projects, it's expected to be the same as the `full` format.

## List issues

> - The `due_date` property was [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/233420) in GitLab 13.3.
> - The `weight` property moved to GitLab Premium in 13.9.
> - The `due_date` filters `any`, `today`, and `tomorrow` were [introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/78460) in GitLab 14.8.

Get all issues the authenticated user has access to. By default it
returns only issues created by the current user. To get all issues,
use parameter `scope=all`.

WARNING:
The `assignee` column is deprecated. We now show it as a single-sized array `assignees` to conform
to the GitLab EE API.

WARNING:
The `epic_iid` attribute is deprecated and [scheduled for removal](https://gitlab.com/gitlab-org/gitlab/-/issues/35157) in API version 5.
Please use `iid` of the `epic` attribute instead.

WARNING:
The `assignee` column is deprecated. We now show it as a single-sized array `assignees` to conform to the GitLab EE API.

WARNING:
The `epic_iid` attribute is deprecated and [scheduled for removal](https://gitlab.com/gitlab-org/gitlab/-/issues/35157) in API version 5.
Please use `iid` of the `epic` attribute instead.
