Issue event types

In this article

For the Issues Events API and Timeline API, learn about each event type, the triggering action on GitHub, and each event's unique properties.

Issue events are triggered by activity in issues and pull requests and are available in the Issue Events API and the Timeline Events API. Each event type specifies whether the event is available in the Issue Events or Timeline Events APIs.

GitHub's REST API considers every pull request to be an issue, but not every issue is a pull request. For this reason, the Issue Events and Timeline Events endpoints may return both issues and pull requests in the response. Pull requests have a pull_request property in the issue object. Because pull requests are issues, issue and pull request numbers do not overlap in a repository. For example, if you open your first issue in a repository, the number will be 1. If you then open a pull request, the number will be 2. Each event type specifies if the event occurs in pull request, issues, or both.
