Update on previous post: I was able to find the documentation for PayPal Payments Advanced in the tutorial section where it explains how to set it up for CafeCommerce. I'm assuming the settings are the same for eCart6? I was able to get a transaction to go through but it only sent the credit card info. No billing or shipping address was received on the PayPal side. Is there any documentation on eCart 6 and PayPal Payments Advanced? I've set up many websites with eCart 5 and Authorize.net or PayPal Payments standard and had nowhere near the trouble I'm having with eCart 6 and PPA.
