Sitecore e-commerce new payment provider

I'm having an issue with sitecore e-commerce since I'm very new to it ,I couldn't find any clear steps开发者_JAVA百科 or code snippet about how to implement a new payment provider , I know that the Authorize.net is already implemented but I need to add PayFlow Pro payment provider , do I have to do new code changes ?if yes what are they ? please help

http://sdn.sitecore.net/upload/sdn5/products/sefe/sefe101/sefe_developers_cookbook-a4.pdf Page 26 will help you :)

The SEFE 1.1 Payment Method Reference Guide provides details for "Implementing a New Payment Provider", including how to register it with Unity and step by step code samples for implementing the Sitecore.Ecommerce.DomainModel.Payments.IOnlinePaymentProvider interface.

Otherwise I've taken to ripping the provided SEFE Payment Providers apart using something like ILSpy or Reflector.

I've just blogged about how to create an on-site payment provider, but the steps I show could be used for an off-site payment provider with a little tweaking.
