PSD2 in a Nutshell

The primary goal of the Payment Service Directive-2 (PSD2) is to create a single integrated market for payment services by standardizing the regulations for banks and payment service providers. The PSD2 will induce transparency and fair competition, and will strengthen the user’s requirements of being offered secure payments services.

Testing / Testdata

The sandbox is the dedicated environment for testing your application. It contains a simulator for the various API responses. You may use any REST capable client like POSTMAN for execution but you need to use the provided credentials (Client-ID and Client Secret).

The simulator only supports the exact requests explained in the documentation of each API. To get a response the request has to match specific input parameters like IBAN, consent-ID, transaction-ID, etc. If the simulator gets a request that does not match a request from the documentation, it will return a correlating error message.

The security mechanisms of the sandbox are the same as of the productive environment. In contrast to productive environment the sandbox has no consent page for the authorization code grant flow. The consent is given implicitly allowing you for testing the complete flow without any physical user interaction.

Please check out all necessary information regarding our test data. The test documentation can be downloaded from the link given in the footer of the API Portal. The link will be visible for users logged in to the portal.
