To use the API you have to register your application. Application registration is available after you login. During the registration process you must fill the certificate field with the public part of a valid QWAC (Qualified Website Authentication Certificate). You will find a test certificate below. 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. Check the API description for the details.
