Transaction Processing
Integrating Cardinal Centinel and 3-D Secure with your PayPal transaction processing is fairly
straightforward. You need to set up a web page that can handle a return call from the card’s
issuer, insert three additional requests into your application before the direct payment request,
and add 3-D Secure payer authentication fields to the DoDirectPayment request.
NOTE: Refer to the Cardinal documentation for the most recent Cardinal Centinel
information. Cardinal requests, responses, and processes are provided for you in this
document as a convenience but might not reflect the most current Cardinal
information.
