I appreciate everyone's input on this... However I do not have the technical skill to work with an API.
Bitpay and the like do not have plugins for 3dcart (the cart I use). However I think I developed a solution that will work until a plugin is developed.
David, I don't mean to beat this into the ground, but it seems like you haven't read any of my responses about this.
Paysius wrote a custom plugin for a shopping cart system they didn't currently support on request from a customer.Why not contact them and see if they will write one for you?
