We strongly want to customize which credit cards we take. Our users are confused since we don't take AMEX but it says that we do on our event forms! Please allow user to customize. Also one critical field is missing in the API integration with Authoriez.net. I can't pass back the ID of the event I am paying for so our bookeeping has no idea what to process the payment against! It is in the API but you have chosen not to expose to the UI and it is not a required field. PLEASE!!!!! Help us!!!!!!
