hello,

I am configuring the FirstData merchant account for my client. here is the instructions..

https://firstdata.zendesk.com/entrie...n-Instructions

which is asking for some changes in the file "authorizenet.php" in /includes/modules/payment directory. In this directory there is also two other files which could be touched and updated with the changes which is required for authorizenet.php file. These two files are :
authorizenet_aim.php
authorizenet_echeck.php

does anyone know if these changes to the other two files ( mentioned above) is needed? The clinet is only processing CC at this time..

All the best
