Authorize.Net enables merchants to authorize, settle and manage credit card and electronic check transactions via Web sites, retail stores, mail order/telephone order (MOTO) call centers and mobile devices.
The Advanced Integration Method is the recommended connection method and offers the most secure and flexible integration. AIM allows merchants to host their own secure payment form and send transactions to the payment gateway using an end-to-end secure sockets layer (SSL) connection.
- Employs industry standard secure data encryption technology - 128-bit Secure Sockets Layer (SSL) protocol.
- Uses transaction key authentication for ultimate security.
- Allows control over all phases of the customer's online transaction experience.
- Configurable transaction response integrates easily with merchant applications.
The Advanced Integration Method will be included in tomatocart v1.1.7 and is available as a separate add-on for existing store owners who are running earlier versions of tomatovcart.
