What is the XML Gateway?
The XML Gateway enables web applications to communicate with customer systems through the exchange of XML documents rather than through the standard HTML interface. All business object methods that are available through the web interface can also be made available through the XML interface. Customers interact with the Gateway by submitting XML request documents and receiving XML response documents back. The Gateway provides a flexible and convenient channel through which to interface your web application with other automated systems being used by customers and/or the merchant.
