Turn NAB Connect into an API

What you can build on NAB Connect

• Get account balances

  Build this

  Reads the Account summary under the Accounts menu, with the Current or End of day balance of every account your User can see.

  Balance view (Current or End of day), account group (optional)

  Returns

  Account name, account number, balance, balance view

• Get transaction history for an account

  Build this

  Reads Transaction history in the Simple view for one account and period: each transaction with the running balance.

  Takes

  Account number, period start, period end

  Returns

  Date, narrative, debit, credit, running balance

• Check payment statuses

  Build this

  Reads the Payment register for a date range, with each payment's status, such as Requires authorisation, Requires repair or Processed.

  From date, to date, status (optional)

  Returns

  Payment ID, description, value date, amount, status

• Create a Pay anyone payment for authorisation

  Build this

  Fills in Pay anyone (Domestic) with a payee, amount, date and reference, then selects Submit so the payment waits in the Payment register for an Authoriser.

  Payment method, pay from account, payee, amount, payment date, reference, description

  Returns

  Payment ID, payee, amount, payment date, status

Automate NAB Connect with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• End of day balances, every account, each morning

  Build this

  Starts

  Every weekday at 7:30, Australia/Sydney time

  Step 1

  Get the Account summary balances with the End of day view.

  Step 2

  Have an AI step add up the balances across all accounts.

  Step 3

  Email you the balances, one line per account, with the total.

• Payments that need someone, posted to your team

  Build this

  Starts

  Every weekday at 14:00, Australia/Sydney time, before the 6:30pm overnight cut-off

  Step 1

  Check the Payment register for today's payments.

  Step 2

  Keep payments in Requires repair, Requires approval, Requires authorisation, Rejected or Failed.

  Step 3

  Keep the ones that were not there on the last run.

  Step 4

  Post Payment ID, description, value date, amount and status to your Slack webhook.

• Yesterday's transactions, handed over to accounting

  Build this

  Starts

  Every weekday at 6:30, Australia/Sydney time

  Step 1

  For each account you name, get yesterday's transaction history.

  Step 2

  Stop when no account has a transaction.

  Step 3

  Post each transaction's account, date, narrative, debit, credit and running balance to your ERP webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get account balances” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "nabconnect.nab.com.au/get_account_balances",
    "input": {
      "balance_view": "End of day"
    }
  }'

{
  "status": "completed",
  "data": {
    "balance_view": "End of day",
    "accounts": [
      {
        "account_name": "Acme Operating Account",
        "account_number": "08-200-1234",
        "balance": 184230.55
      },
      {
        "account_name": "Acme Payroll Account",
        "account_number": "08-200-5678",
        "balance": 42910
      }
    ],
    "count": 2
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

NAB Connect’s own options

NAB's NAB Connect pages describe no API for the people who sign in. Automated reporting sends Account Information Files and reports to your SFTP server at no extra charge, set up through your banker. NAB Direct Link, a separate SFTP service, takes payment files and returns acknowledgements and account reports.

Signing in to NAB Connect

NAB Connect signs you in with your 10-digit User ID and a password. Users who need a security device, usually Authorisers and Administrators, enter a one-time passcode from the NAB Connect app's mobile token or a physical token instead. With Fous you sign in through NAB Connect's own sign-in with your own User: the login is sealed with AES-256, and a password User is signed back in when a session expires.

Worth knowing

Submitted payments wait for an Authoriser

Submit sends a payment to Requires authorisation. An Authoriser approves it with a one-time passcode from a token, and with Segregation of Duties on, that must be a different User from the creator.

Cut-off times decide the processing day

Overnight domestic payments, Direct Credit and Payroll have a 6:30pm AEST/AEDT cut-off, BPAY 6:00pm and RTGS 3:50pm. Later ones process the next business day. Fast payments have no cut-off.

Export limits on the Payment register

One export holds at most 5,000 payments. Without a date range, the export includes up to 12 months of payments.

The Simple CSV leaves out payment details

Fast payment details and international payment details are not included when you export Simple transaction history to CSV.
