# Issues API

Every API call to issues must be authenticated.

If a user is not a member of a project and the project is private, a `GET`
request on that project will result 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).

## List issues

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`.

```
GET /issues
GET /issues?state=opened
GET /issues?state=closed
GET /issues?labels=foo
GET /issues?labels=foo,bar
GET /issues?labels=foo,bar&state=opened
GET /issues?milestone=1.0.0
GET /issues?milestone=1.0.0&state=opened
GET /issues?iids[]=42&iids[]=43
GET /issues?author_id=5
GET /issues?assignee_id=5
GET /issues?my_reaction_emoji=star
GET /issues?search=foo&in=title
GET /issues?confidential=true

Users on GitLab [Starter, Bronze, or higher](https://about.gitlab.com/pricing/) will also see
the `weight` parameter:

```json
[
   {
      "state" : "opened",
      "description" : "Ratione dolores corrupti mollitia soluta quia.",
      "weight": null,
      ...
   }
]
```

**Note**: `assignee` column is deprecated, now we 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][ce-17042]. This value will only be present for issues which were closed after GitLab 10.6 and when the user account that closed the issue still exists.

**Note**: `assignee` column is deprecated, now we 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][ce-17042]. This value will only be present for issues which were closed after GitLab 10.6 and when the user account that closed the issue still exists.
