I look at PayPal APIs (god there are so many!)
My question is this: It seems that there are two releases for the proxy server for websites (direct and payflow edition). See the link below for two guides:
https://www.x.com/developers/paypal/development-integration-guides#wpp
After talking with paypal, it seems they recently switched and create new pro accounts in the payflow release, while old accounts are still a direct payment issue. There is a new authentication scheme for the new payment edition API.
1) Does anyone know if these two APIs are completely different? They are both called proxies, but I have no idea about the APIs themselves.
2) Do they allow transparent forwarding if they are different.
3) For express verification, different API calls, if I use api express verification directly, vs with pro (direct or payment flow releases).
Thanks for easing my confusion. :)
