Hello,
Again, sorry for the delay.
I looked into this more and the EventBrite API still only has an option for PayPal.
So tickets purchased though our plugin unfortunately can only use PayPal, we have not other option.
It appears that on EventBrite they have 3 different options for people to setup and I do not know why they have not extended their API to include all of them.
I am going to update our EventBrite Ticket Product Page to make that clear.
If you feel the plugin is no longer going to work for you because of this fact, please contact us at pro(at)tri.be and we can work out a refund.
Sorry for the late replies and let me know if you would like anything else and I can take care of it.
Brian
