We’ve added a new function to our NAB Transact eCommerce solution. You can now conduct an Account Verification Check (also called $0 Auth) through XML API, the NAB Transact Portal and our Mobile Portal.

This new functionality will allow merchants to validate a customer’s card number before saving the card details against their account for later use (to make Card on File or recurring payment transactions, for example).


Just download the updated Integration Guide for NAB Transact, and have a look over the instructions for the new function. We’ve also put together some FAQs below that might help.

If you have a question that’s not listed here, give the NAB Merchant Service Centre a call on 1300 369 852 – they’ll be happy to help out. Please make sure you select Option 3 for NAB Transact and then select option 1 for any technical queries.
