Authorize.net provides one secure location where merchants can manage everything related to transaction processing, from running secure transactions or setting up their Web sites to run transactions for you. With Authorize.net, merchants can review transaction reports, get technical support and integrate with their Bookkeeper software program.

Developers, software programmers, Internet service providers (ISPs) and commerce service providers (CSPs) with an advanced knowledge of the C or Java programming languages prefer to use the API (application programming interface) client to integrate secure credit card processing into both simple and complex e-commerce Web sites. This allows customers to pay for products and services online with a credit card without leaving the merchant's Web site. Secure Sockets Layer (SSL) technology is used to encrypt confidential transactions and order information and to pass them directly from the e-commerce site to the Secure Payment Gateway.
