- For Authorize.NET no server components are required. The communication between shopping cart on the server and a Payment Gateway is accomplished via secure HTTPS protocol.

ASP, Cold Fusion or Perl (Linux) code can be used to "talk" to the PayPal servers. The code needs to be incorporated to your web pages/scripts and be executed after your customers have submitted credit card information and confirmed purchase (submitted a form).
Code examples and additional information for PayPal Gateway you can find on PayPal PayFlow web site.
Attention: PayPal has acquired VeriSign's Payment Services, including CyberCash and the payment gateways, Payflow Link, and Payflow Pro >>>>
