We publish data about our mobile and PSD2-regulated API performance every quarter.

The data shows the quality of service we provide to third parties building banking apps using our APIs. It is important to us to demonstrate that we provide the same level of service to third parties that we give to our own app.

If you’d like to read more about our APIs, you can check out our developer documentation, and you can find more information about the revised Payment Service Directive (PSD2) in general here.
