Open Banking Standard version 3.1.10

We have moved to the OBIE Specification Version 3.1.10, which is the final release under the CMA’s revised roadmap.

This version includes updates on:

  • 90-day reauthentication, which means that the customers do not need to reauthenticate details with their ASPSPs every 90 days. For more details, please see here - (link to the attached document to be added)

  • Transaction Risk Indicators, which can help ASPSPs understand the purpose of the payment.

  • The adoption of more customer-friendly terminology to improve customer awareness and understanding of open banking technology.

  • Known issues, driven by errata identified in version 3.1.9.
