Register an application

Before you can use an API you have to register your application. When you register an application, the application is assigned a unique client ID and client secret. You must use the client ID when you call an API that requires you to identify your application by using a client ID, or a client ID and client secret.

To use PSD2 APIs, you also need to add the public part of a QWAC (Qualified Website Authentication Certificate) when registering your application. For this purpose please use the test certificate from here.

Check the API description for the details.

Select a plan

Finally, now that your application is registered, you need to subscribe to a plan. The plan determines the number of API calls that your application can make.
