You can validate your integration by using the test cases described for the payment product you want to test. These test cases can be used against the sandbox environment and in certain cases also the pre-production environment.* Note: Not all payment products have test cases
How to use test cases
Select the payment product you want to test.
Create the API request based on our API Docs or the examples on the integration page of our payment products.
Send in request to the right endpoint, either for sandbox or for pre-production.
Use the API Explorer, available when you log in to the environment, which provides pre-defined examples.
