Can be one of: <ul><li> `created` - A new check run was created.</li><li> `completed` - The `status` of the check run is `completed`.</li><li> `rerequested` - Someone requested to re-run your check run from the pull request UI. See "[About status checks](/articles/about-status-checks#checks)" for more details about the GitHub UI. When you receive a `rerequested` action, you'll need to [create a new check run](/rest/reference/checks#create-a-check-run). Only the {% data variables.product.prodname_github_app %} that someone requests to re-run the check will receive the `rerequested` payload.</li><li> `requested_action` - Someone requested an action your app provides to be taken. Only the {% data variables.product.prodname_github_app %} someone requests to perform an action will receive the `requested_action` payload. To learn more about check runs and requested actions, see "[Check runs and requested actions](/rest/reference/checks#check-runs-and-requested-actions)."</li></ul>
