Greater Bank

Greater Bank is a customer-owned Australian retail bank headquartered in Newcastle, New South Wales, offering everyday transaction and savings accounts, term deposits, home loans, personal loans, and credit cards to personal and business customers. In March 2023 Greater Bank merged with Newcastle Permanent to form Newcastle Greater Mutual Group (NGM Group), one of Australia's largest customer-owned mutual banking organisations, while continuing to trade under the Greater Bank brand. As an Authorised Deposit-taking Institution (ADI) it is a designated data holder under Australia's Consumer Data Right (CDR / Open Banking) and exposes a public, unauthenticated Product Reference Data (PRD) API conforming to the Data Standards Body (DSB) Consumer Data Standards. Consumer-data sharing beyond PRD runs on the accredited CDR data-recipient (ADR) model with OAuth2/OpenID Connect FAPI-profile security.

Greater Bank publishes 7 APIs on the APIs.io network, including Banking Account Balances API, Banking Account Direct Debits API, Banking Account Scheduled Payments API, and 4 more. Tagged areas include Financial, Banks, Open Banking, CDR, and Consumer Banking.

Greater Bank’s developer surface includes authentication, documentation, getting-started guide, API reference, support, and 19 more developer resources.
