What is GitHub’s repository dispatch event and how does it enable cross-repository workflow triggering?

Accepted Answer

GitHub's repository dispatch event is a custom webhook that triggers workflows across repositories. It enables cross-repository automation by sending a POST request with a custom event type and payload. This allows external systems or repositories to programmatically trigger workflows. Incorrect options misinterpret the dispatch event's purpose.
