Can we integrate Json request & reply in iReceivable application to process credit card payments

Dear iReceivable Guru,

We have a question around our iReceivable credit card payment processing and would like your feed backs & comments.

We have already a custom Credit Card process using for several of our web applications. This custom credit card process uses JSon request&reply call from our

web application to our credit card engine(bank). We have already establish with our bank all the necessary integration for passing CC data back and forth.

Options:

1- We would like to know if we can use the same above mentioned process and integrate it with our Oracle iReceivable Payment processing?

Basically personalizing our Oracle iReceivable external facing page to invoke a our custom CC Payment call(set at Charge) to our bank by passing all the requested CC information to our bank and receiving back the CC result from the call and store it in our customer's payment record in our Oracle Receivable application.
