Some may be looking for some direction/discussion on integrating with Authorize.net's AIM and ARB API's. Below is a resource that was helpful and is a good resource if you have to roll your own. Good Luck!

Integrate Authorize.net ARB with PHP:
http://www.merchant-account-services.org...lling-api/

Silent Post URL (similar in concept to PayPal's Instant Payment Notification):
http://www.merchant-account-services.org...-failures/

Just looking to make one-time payments alone?
Integrate Authorize.net AIM with PHP (solely):

I'm not sure if you'll get a satisfactory answer. The reason being that, developers tend to go with the gateway the client wants to use, and it's generally the fees that dictate which gateway to use rather than ease of integration.
