Right now I am using PayPal Websites Payments Standard with DiscountASP.NET and it works fine. However, I would like to upgrade to either PayPal Websites Payments Pro or PayPal Payflow Pro in the upcoming months. Is it possible to use these systems with DiscountASP.NET?
Website Payments pro is supported (see http://kb.discountasp.net/article.aspx?id=10419), but Payflow pro is only supported on IIS 6 (see http://kb.discountasp.net/article.aspx?id=10567). Verisign has a "Payflow pro" too, so it gets confusing, but I think the above is correct.
