NAB and personal API access
NAB does not hand customers an API key for their own accounts; the regulated route is a Consumer Data Right (CDR) consent, which is what BankSync uses.
You approve sharing on NAB’s own CDR consent screen, pick the accounts and how long the consent lasts (up to 12 months), and BankSync receives the data as a CDR Representative of Fiskil Pty Ltd (ADRBNK000246). Your key reads it back as JSON.

Frequently asked questions
Does NAB offer a personal API?
NAB does not hand customers an API key for their own accounts; the regulated route is a Consumer Data Right (CDR) consent, which is what BankSync uses.
What data can I read from my NAB accounts?
Transactions and balances, read-only, as JSON. The first sync reaches back up to 7 years; how far back NAB actually returns can vary by account.
How long does consent last?
A CDR consent lasts up to 12 months; you choose the duration on NAB’s consent screen. When it ends, reconnect from the app and approve again. You can withdraw consent at any time from NAB or from BankSync.
Is the API read-only?
Yes. The connection your bank grants is read-only: BankSync can read account data, and it cannot move money, make payments or change anything at your bank. Your API key reads the same data, scoped to the permissions you give it.
Can I use my NAB data with Claude or ChatGPT?
Yes. The same read-only data is available over BankSync’s MCP server: point Claude, ChatGPT or Cursor at it and ask about your NAB transactions in plain English. It is included from the Standard plan.
What about NAB business accounts?
Which business and commercial accounts NAB shares varies, so we do not promise them here. Contact support with your account type before you rely on it, and we will tell you what connects.
Other Australian banks
The same key reads every bank you connect.
