With our old site that was powered by zen-cart, once a customer completed their order through our site using authorize.net their shipping info would be sent to authorize.net and the order would be automatically confirmed and processed. Now with nopcommerce, authorize.net is telling us that they are not receiving that info from our site and that the problem would be on our end. Why are they not getting this info and how do i fix this so our orders will be auto confirmed?
