I wonder how to integrate 3DS2 in Drupal 6? I looked everywhere, everything I found is related to Drupal 7 or higher.
Somebody in Dublin wants us to upgrade their gateways to support HPP SCA. They used Realex as a gateway before, but it's no longer supported.
Now they're asking us to make a new gateway based on the GlobalPayments HPP SDK. We followed the steps and created a gateway, but when we tested it we got the 508 error:
Invalid Data in MERCHANT_ID. Please contact the merchant.
I am not even sure if HPP is supported by Drupal 6 or not and they are convinced that there is no difference between Drupal 6 or 7, what works for Drupal 7 can work for Drupal 6 too.
Any idea?
