I'm having the same issue. I was loosely following the guidelines on this page, but I can't get the payment to go through. Has anyone figured this out? Is there another way of making this payment?
I'm having some trouble with the CapturePayment step; I keep getting the message "Payment Attempt Failed". Going in through the admin UI, finding the invoice, and clicking 'Attempt Payment' works (changing nothing else gathered from previous steps).
I'm using authorize for the payment method in the order.
Can you tell me what I may be doing wrong?
Thanks.
