Hi, kevinwalzakcom. Great question! 🙂
We totally agree with you about adding more payment processing options for the ticket iFrame. Unfortunately, the Eventbrite API does not offer these options to us as a third-party developer. Here was the word from their support last week:
“As Events Calendar Pro utilizes the Eventbrite API it is constrained to the methods we provide. In the payment_update we have not included credit card processing as an option for fraud and security reasons as this would require someone to enter their mailing address or direct deposit information via the API. I’m sorry for the inconvenience and I will submit the feedback to our Product Manager and see if this will be an option in the future!”
If you’d like to get in touch with their support and let them know how much you would value access to other payment methods, we’d be very grateful, but for now, I’m afraid our hands are tied. Sorry I don’t have better news for you!
