Web Service API

Global Gateway e4℠ Web Service API (Application Programming Interface) is comprehensive payment processing software for the merchant who requires a more sophisticated payment solution.

Global Gateway e4℠'s API gives merchants complete control over how their payments are processed, and allows them to build transaction processing applications that can process payments from a web site or from multiple point-of-sale terminals. Ideal for either e-commerce or large-scale retail situations, the Webservice API uses Secure Sockets Layer (SSL) technology to encrypt and pass confidential transaction and order information directly to Global Gateway e4℠.
