Open Banking

On 9 May 2018 the Government announced its intention to introduce a new Consumer Data Right (CDR) law in Australia. Put simply, the Consumer Data Right puts control of your data in your hands.

In Australia, ‘Open Banking’ is the banking sector's implementation of the CDR.

From July 2021, St.George customers will have the ability to share selected banking data with trusted third parties, including other banks, online. 

St.George Open Banking Product API

The St.George Open Banking Product API (Application Programming Interface) enables third parties to retrieve information about products that St.George currently offers. It is designed and documented to support the Australian Consumer Data Standards.

Our Product API includes products for both retail and business customers such as:

  • Transaction Accounts
  • Savings Accounts
  • Term Deposits
  • Credit Cards    

Data for additional products will be progressively added to the API in line with the timeframes specified by the Consumer Data Right rules.
