Setting up this Gateway

The Requires NAB option for this gateway is the "Application Programming Interface" as shown HERE

Once the account is set up with NAB, this Gateway does not have any specific setup requirements for standard operation.  Simply log into your site, navigate to eCommerce -> Payment gateways, select this gateway from the dropdown list, and enter the requested information.

NOTE - The Username/Merchant number is a 7 digit number and can not be anything else. All their Usernames are in the format of 3 letters + 4 numbers.

Setting up for Recurring Billing (If required)

The implementation of this payment gateway does not support recurring billing


ERROR: An error occurred while processing credit card

Object reference not set to an instance of an object

This error is typically shown when attempting to process a payment if the username and password you are using is not correct, or if your gateway is in a 'test' mode.  You will need to conact NAB to confirm you are using the correct credentials.
