The third use case in the Eventbrite business scenario is used for managing attendees. This page describes the related tasks and the operations you use in the Eventbrite connector and the other ESB connectors.

The flow for managing attendees is illustrated in the following diagram. The ESB connectors for GoToWebinar will be used to connect to each service.
...
- Retrieve event attendees from the Eventbrite API for selected events using the eventAttendees operation.
- Create Registrants in the GoToWebinar API using the createRegistrant operation.
