Events

An event is a specific activity that triggers a workflow. - For example, activity can originate from GitHub when someone pushes a commit to a repository or when an issue or pull request is created. - You can also use the repository dispatch webhook to trigger a workflow when an external event occurs. - For a complete list of events that can be used to trigger workflows, see Events that trigger workflows.
