Advanced Integration Method

Advanced Integration Method (AIM)

AIM is Authorize.Net’s 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.

AIM is the required connection method for shopping cart developers participating in the Authorize.Net Shopping Cart Certification (SCC) program.

  • 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.
