Hello,
When setting a payment method by CC the only available option for Authorize.net is AuthorizeNet.Aim. Using this setup let your customers enter their CC information on YOUR server... and will need to add numerous security options to get this going.
I am currently using AuthorizeNet.Sim on our X-Cart cart and this redirects the customer to the Authorize.Net site which keeps all the CC information from customer... this way you can sleep at night without worrying about CC thefts info from your site.
How can we get the correct API for Authorize.Net with the SIM option and not the available AIM?
Best
Philipp
