I am using the eventbrite API through the eventbrite client gem to generate concerts from my site.
On my concerts#show page I embed the ticket widget for users to buy tickets. From there, users will be led to eventbrite.com's concert page to complete the purchase. Then they get redirected to a return url on my site that I can define.
The question is: How do I know if someone bought a ticket? Or am I just blind and cannot find it in the documentation?
