Use case

Think outside the box! Blaze new trails with our APIs

Commerzbank APIs offer more than just banking solutions.

Take “two-factor authentication” for example: you can ensure that you really are communicating with one of your customers. Two-factor authentication increases security for both you and your customer.

To this end, we provide Commerzbank customers with our Approval API in addition to the Login API.

This, and many other examples, just scratch the surface of what possibilities our APIs open up for you.
