Ok when you pass the "Amount" variable to the versign page (or other similar services) the customer can enter his other details and proceed with the payment...
How can my own page get informed that the process has been finished succesfully and the amount has been deducted from my customer's credit card?
I mean ok I passed the variables to the payment gateway, but before I ship the products I need to know that everything is ok....
Thanks for your reply in advance.
