Alliance has created an open, XML based web services interface to allow our merchants to interface with the Alliance system allowing developers to build integration and custom applications by leveraging the Alliance Gateway as a development platform.

Using our XML Web Services, the Alliance Gateway can be easily extended and integrated with any other enterprise applications, or extended to create entirely new solutions.

Alliance's Web Services removes the need for the GUI and allows developers to directly hook into and control all of the functionality normally performed by the Alliance Gateway.
