Capital One UK Open Banking Interface

The Capital One UK Open Banking Interface allows authorised Account Information Service Providers to access account information, including balances and transactions for our customers. It also allows authorised Card-Based Payment Instrument Issuers to confirm funds in an account.

Our implementation follows the UK Open Banking specification, available at Open Banking.

To use the interface you must be registered with the Financial Conduct Authority (FCA) as an Account Information Service Provider (AISP) or a Card-Based Payment Instrument Issuer (CBPII).

In order to get in contact with The Open Banking team at Capital One UK you can email Capital One Open Banking Support.

You can get started by Testing in the Sandbox.
