Labels

About the Labels API

The Labels API supports managing labels for a repository and adding or removing labels to issues and pull requests. Every pull request is an issue, but not every issue is a pull request. For this reason, "shared" actions for both features, like managing assignees, labels, and milestones, are provided within Issues API.
