# Issues 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](README.md#pagination).

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

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 `weight` property moved to GitLab Premium in 13.9.

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 in API version 5](https://gitlab.com/gitlab-org/gitlab/-/issues/35157).
Please use `iid` of the `epic` attribute instead.

NOTE:
The `closed_by` attribute was [introduced in GitLab 10.6](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/17042).
This value is only present for issues closed after GitLab 10.6 and if the user account
that closed the issue still exists.

## List group issues

> The `weight` property moved to GitLab Premium in 13.9.

Get a list of a group's issues.

If the group is private, credentials need to be provided for authorization.
The preferred way to do this, is by using [personal access tokens](../user/profile/personal_access_tokens.md).

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 in API version 5](https://gitlab.com/gitlab-org/gitlab/-/issues/35157).
Please use `iid` of the `epic` attribute instead.

NOTE:
The `closed_by` attribute was [introduced in GitLab 10.6](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/17042).
This value is only present for issues closed after GitLab 10.6 and if the user account that closed
the issue still exists.

## List project issues

> The `weight` property moved to GitLab Premium in 13.9.

Get a list of a project's issues.

If the project is private, you need to provide credentials to authorize.
The preferred way to do this, is by using [personal access tokens](../user/profile/personal_access_tokens.md).

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

NOTE:
The `closed_by` attribute was [introduced in GitLab 10.6](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/17042). This value is only present for issues closed after GitLab 10.6 and if the user account that closed
the issue still exists.

## Participants on issues

If the project is private or the issue is confidential, you need to provide credentials to authorize.
The preferred way to do this, is by using [personal access tokens](../user/profile/personal_access_tokens.md).
