Payment processing service

The payment processing service is an inbound Web service responsible for processing online financial transactions such as payment authorizations and payment captures. This inbound Web service is typically called by an external system in integrated solutions where the external system has no direct integration with payment service providers, but relies on the WebSphere Commerce payment processing system and its payment plug-ins to process online financial transactions.
