Starling is a champion of the API economy and Open Banking. This is a ground zero commitment for us: back in 2014 when Starling was founded we decided to build our bank on open APIs from Day 1. We did this not because it was a legal requirement, but because we felt - and still do feel - that it was the right thing to do.

We have also had a deep-seated belief in the importance of transparency from Day 1.

On this page, we are publishing our quarterly PSD2 API performance data. This shows the quality of service we provide to third parties building banking apps. As part of this process 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.
