Metro Bank was founded on the idea that customers should be able to bank when it suits them. That’s why our stores are open 7 days a week, from early ‘til late. This idea now extends beyond our stores and our apps. We want to partner with developers to help bring the Banking Revolution to customers however they choose.

Metro Bank is working to deliver an API-based interface solution to enable Account Information Services and Payment Initiation Services in line with Open Banking standards.

This continues to be our long term strategic solution with our version 3.1.1 API sandbox already available for registration here.

In the meantime we are delivering a Modified Customer Interface (MCI) to provide a Third Party Provider (TPP) access interface for PSD2 compliance by the end of the Adjustment Period (14 March 2020) with a Test Facility available now. Information on how to register for and use the MCI is available here.
