FAQs

What is the MCI?

The MCI is our Modified Customer Interface and is Metro Bank's initial PSD2 compliant solution for Third Party Providers (TPPs). The MCI will be available until it is superseded by our API services (v3.1.1). The MCI and v3.1.1 API services will coexist for a period of time to enable TPPs to migrate to the API Services.

What can be accessed through the MCI solution?

The MCI allows TPPs to screen scrape on both our Retail and Business Banking or Business Online Plus and Commercial Online Banking platforms. When making a call to use the MCI, the TPP must identify the relevant platform to enable an automatic redirection.  

What about the MCI Test Facility?

The MCI Test Facility works in the same way as the MCI Production service will once it's available but uses non-production versions of our Retail and Business Banking or Business Online Plus and Commercial Online Banking platforms. If you wish to make use of the Test Facility, please contact us here. Our support team will issue you with login credentials and test data that will enable you to utilise all PSD2-related services available through those platforms.

Why do I have to register separately for MCI and API Services?

At present, the MCI is the only service connected to the new Open Banking Dynamic Client Registration process. We are working to support registration for Open Banking APIs through Dynamic Client Registration so you will only need to register once to access all our services.

Are there any functions available to customers that TPPs cannot access via the MCI Test Facility?
