In most cases, connecting your NAB account to ACSISS My Data is a straightforward process. However, if you don't see the business account you intend to connect, you'll need to take extra steps.
If you are a NAB Connect user
You must contact the bank and have these accounts linked to your NAB Internet banking profile.
Nominate an authorised user
Before sharing your data, you must add a new nominated authorised user.
Any existing and new nominated authorised users appointed by your business owners will be able to provide consent to share the data in relation to the accounts for which they are authorised.
To add a new nominated authorised user, you’ll need to fill out this Authorised User Nomination form. Once you’ve completed the form, return it to NAB.
Once you’ve added a new authorised user, you should be able to connect your NAB business account to ACSISS My Data.
For further details, you can visit NAB's page dedicated to open banking or reach out to NAB directly.
