NAB API
There's no public NAB developer API you can sign up for. Redbark gives you one REST API for your NAB accounts, balances, and transactions over CDR Open Banking, hosted in Australia.

The closest thing to a NAB API
Like every Australian bank, National Australia Bank only shares customer data through the Consumer Data Right (CDR) Open Banking framework. There's no public developer portal where you register an app, and scraping your own login is brittle and breaks the bank's terms.
Redbark connects to NAB over CDR and turns it into one REST API. You get NAB accounts, balances, and transactions as JSON, without becoming an accredited data recipient yourself and without handing us your NAB login.
Pull NAB transactions in two calls
Authenticate with your API key, then call the same endpoints you'd use for any connected bank. Here's NAB.

NAB in your terminal
Prefer the command line? The open-source Redbark CLI lists your NAB accounts, balances, and transactions as readable tables, or raw JSON with a flag. It uses the same API key.
