I am working on a shopping cart and I am setting up credit card processing with Authorize.net (using AIM). This is my first time to do this, in searching I have found a lot of examples using curl but my webhost does not have it installed. So I will have to do this with a SSL. I don't know where to start on this one, I have done many searches but not gotten very far. Does anyone know of any tutorials or sources on the subject?
