Authorize.Net AIM Integrator
The Advanced Integration Method (AIM) is the way to Connect your website directly to the Authorize.Net Gateway. It gives you the full control over data used in the processing of a Transaction and allows you to keep the customer on your own website during the whole transaction process. However, implementing AIM connectivity requires some programming skills, as AIM employs your server to forward data to the Authorize.Net gateway.
With Authorize.Net AIM Integrator, you can take advantage of AIM connectivity with a minimum of coding; simply provide the configuration data.
