This version of GitHub Enterprise was discontinued on 2023-07-06. No patch releases will be made, even for critical security issues. For better performance, improved security, and new features, upgrade to the latest version of GitHub Enterprise. For help with the upgrade, contact GitHub Enterprise support.

After a site administrator upgrades your Enterprise Server instance to Enterprise Server 3.9 or later, the REST API will be versioned. To learn how to find your instance's version, see "About versions of GitHub Docs". For more information, see "About API versioning."

Issue assignees

Use the REST API to manage assignees on issues and pull requests.

About issue and pull request assignees

You can use the REST API to view, add, and remove assignees on 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 the Issues endpoints.
