Sandbox Environment

Test the integration in a specially prepared Sandbox Environment. Create separate account and products on https://sandbox-app.transaction.cloud. Everything works the same as in the production environment, except that the transactions are virtual and do not result in actual payments.


Testing environment for developers. You can make free test payments without real cards.

Apple Pay

Unfortunately, Apple Pay is only available in production mode due to restrictions imposed by Apple. As a result, sandbox testing for Apple Pay is not possible.
