For PayFlow Pro Customers Using ASP
PayPal is discontinuing support of the PayFlow SDK v3, which is used by eCart 4 for the PayFlow Pro gateway with ASP.
If you have coded your checkout with eCart 4, using Payflow Pro with the ASP server language, it will cease to work, beginning in September.
If you plan to use the PayFlow Pro gateway in eCart in the future, we recommend using PHP as this is the server language WebAssist will continue to support across our product line.
