# Issues

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 to 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 created by the authenticated user.
