I have tried to build a payment module for "Payson" with "2CheckOut" as basis, because it works similar. But now, I hope someone can help me to complete the whole thing because everything works perfectly except for one last detail ...
Immediately when the customer get to Payson website to complete the order, by a bank- or credit card payment, a confirmations mail is sent to the customer. That should not be happend before the payment is finished and the customer returns to the webshop again.
