I am using authorize.net to process AIM & CIM transactions ( Soap service reference ) in asp.net. I want to track Customer IP address & phone number in every transaction. For AIM, I can do this using x_phone & x_customer_ip parameters but in case of CIM I am using extra option parameter of Create Customer Profile Transaction function to pass " x_customer_ip " along with its value. I want to pass these two parameters in CIM
so please tell me how can I pass these two parameters in extra option ?
