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.

We’ve now delivered the Modified Customer Interface (MCI) which will be our dedicated TPP access interface. As a result, we will not be developing APIs at this time. Information on how you can register for the MCI, and a guide to its use, is available here.
