Payment Gateway Support
What is a Payment Gateway
A payment gateway is an eCommerce service that authorizes payments for e-businesses and online retailers. It is the equivalent of a physical POS (point-of-sale) terminal located in most retail outlets. One option to link a web site to the EZ Payment Gateway for real-time transaction processing follows:
XML Gateway API
Link to the XML Gateway API (The XML gateway API is a programming interface that resides on transaction servers which communicate directly to credit card processing networks). The programming interface requires that the merchant, or their web programming staff, be sufficiently knowledgeable in programming skills in any programming or object oriented scripting language. The XML Gateway API accepts the credit card purchasers information, and produces an authorization or decline directly from the merchant bank.
The XML Gateway API provides methods to perform the following operations: AUTH, SALE, SETTLE, CREDIT, VOID and QUERY. The information is passed via 128bit SSL https post in XML format. That post occurs in the background from the merchant's server. Thus the purchaser never leaves the merchant's website. The authorization information is returned in XML format with full error trapping and reporting to indicate the success or failure of the transaction. This is the most secure method and the preferred method.
