Question:
Does the Simple Commerce Module work with Paypal’s Website Payments Pro?
Answer:
No, the Simple Commerce module only supports PayPal Website Payments Standard. That type of account requires an application process and features that are bit more complex site-side, and combined with implementation of the APIs used by Website Payments Pro would definitely have taken the “Simple” out of “Simple Commerce”. It is being considered for inclusion in the full blown Commerce Module, though.
