The Global Gateway API software modules build payment solutions that fit your unique needs. You can pick and choose the modules you need. After you have integrated the Global Gateway API payment module into your Web site, customers can purchase items on your Web site and all payment details are processed automatically. You can review transaction activity by visiting the Global Gateway Virtual Terminal. Here is an example of a simple transaction as it travels through from customer order to approval. 1. A customer makes a purchase from a merchant's online store over the Internet. 2. The ordering information is received by the merchant's CSP or by the merchant's own server (self-hosting). 3. The merchant's customized software receives the information, uses the tax and shipping calculators as needed, calculates the order total and passes relevant order and payment information to the Global Gateway API payment module. 4. The Global Gateway API payment module transports the order data through the secure sockets layer (SSL) pipeline to the Global Gateway API secure server. The Global Gateway API service contacts and transmits the data through a dedicated, secure frame relay system to the banking network. 5. After the transaction is approved and settled, funds are withdrawn from the credit card-issuing bank and deposited into the merchant bank account. 6. A confirmation e-mail is sent to the merchant and the purchaser when the transaction is completed.
