Configure a custom payment plug-in
Follow the same process to configure an custom plug-in as you would follow to configure a plug-in provided with WebSphere Commerce.
If there are special properties that apply to the plug-in, ensure that the deployment descriptor includes those properties. Properties can also be set in the PaymentSystemPluginMapping.xml file. For more information about the deployment descriptor, refer to the Payment plug-in specification.
To use the address information entered by customers, ensure that the address parameters (keywords or name-value pairs) as provided in WebSphere Commerce match the requirements of both the payment plug-in and any payment back-end system the plug-in communicates with. Address information requirements can vary by geography and not all payment back-end systems use the same address data. The payment plug-ins provided with WebSphere Commerce generally process commonly used address parameters
- When configuring the payment methods and refund methods the 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 WebSphere Commerce.
- Ensure the PaymentSystemMappingPlugin.xml file is configured appropriately for the plug-in.
- Set up the payment business policies as appropriate. See Payment, refund and return payment business policies.
- Restart WebSphere Commerce .
ResultsAfter completing these tasks, the store should be able to process payment transactions using the payment plug-in.
