When someone purchases a ticket on event brite, does the attendees info get synced to wordpress? If so, what info? Is this data only in the attendees folder or can it be access to integrate with a CRM API somehow?
The attendee information is all stored in Eventbrite. We do not bring it over to your site.
The event in the Events Calendar is more a front for Eventbrite and enables you some control on creating and modifying the event, but the advance functions remain in Eventbrite.
