Using Payment Rules with an external payment plug-in

To use some other payment plug-in (one that is not already provided by WebSphere Commerce, such as a third-party or in-house produced plug-in):

1. When configuring the payment methods and refund methods your store will use, be sure to specify the payment system name associated with the plug-in you intend to use. The PaymentMethodConfigurations.xml and RefundMethodConfigurations.xml file should contain a payment system name that matches the payment system name known to the WebSphere Commerce Payments. The controller's configuration contains information about the plug-ins that are identified with a particular payment system name.
2. Ensure the PaymentSystemMappingPlugin.xml file is configured appropriately for the plug-in. See Mapping a payment system to a payment plug-in.
3. Set up the payment business policies as appropriate. See Payment business policies for Payment Rules.
4. Restart WebSphere Commerce.

After completing these tasks, your store should be able to process payment transactions using the payment plug-in.
