Short answer: You can list goto webinar items in Go To Webinar by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Go To Webinar List GoTo Webinar Items action to a workflow, map its 0 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
