So I've heard that the test environment provided by PayPal Sandbox is PayPal Pro. My company is not using PayPal Pro, we're using the following: Website Payments Standard, ButtonManagerAPI to create dynamic hosted buttons, and an IPN listener.
How can I make sure my sandbox environment accurately represents Standard Payments? It's no good if I'm offering Standard Payments to my customers but testing my site for PayPal Pro, I might miss something!
