I've dug through the methods in Event Brite API but can't find any reference to QR codes generated by Eventbrite in their native IOS app.
http://developer.eventbrite.com/doc/#methods
without reverse engineering it or sniffing the web urls - can anyone shed some light on how to do this?
Eventbrite barcode information is a sensitive issue - but, Eventbrite is happy to discuss specifics over email
If you just want to build a list of QR codes for the current event owner, you should be able to generate them from the barcode_ids returned from the event_list_attendees API call.
