Once we build our Shopping Cart and Add Shipping Address:
Where is the Controller for OnePage Checkout, that build all the cart information to make the Payload JSOn to go to payment.
Anh how would we write in PHP to Call a Service on another Server.
Have the service Run. then once completed. It will make call to PAge or Script and out URL it complies.
Pretty Much I am trying to use the IFRAM Payment methond in Magento, by encrypting the Shipping / Shopping Cart before Payment (which is the Iframe URL needs to be loaded in)
