Hi Camardo,
Eligible Direct Feeds that currently can be connected with Quickbooks Online are:
Australia and New Zealand Banking Group (ANZ) – Business/Personal Accounts and Commercial Platinum Visa Cards
Commonwealth Bank Australia, National Australia Bank (NAB), Westpac, St.George Bank, Bendigo Bank, Bank SA, Bank of Queensland, Bank of Melbourne, Adelaide Bank and Macquarie Bank all currently support Business and Personal Accounts only.
For more information about supported Direct Feeds please have a look at the following article.
If the Bank you are wanting to connect doesn't support a Direct Feed for a CreditCard, most products can be connected via a Standard Feed. Please refer to this article for further information on connecting a Standard Feed.
Feel free to reply if you have any further questions as we are here to help.
