Enrol a user in a Moodle course automatically when they register for an event on Eventbrite. This uses the Zapier service. You will need an API Key (web services token) for Moodle. If you are a Poodll NET user thats accessible from your dashboard.
If you are standard Moodle user, you will need to create the token and you will need to install the (free) local_trigger plugin. See this page for details:
