Yes. You can add a Chat 2 Pay Sandbox configuration that allows you to test your Chat 2 Pay setup without using 'real' money.

You can have multiple Sandbox Chat 2 Pay configurations in your Chat 2 Pay account. However, note that you cannot promote a Sandbox configuration directly to Production - you will need to create a new Production configuration once you are done testing and ready to start using it in Production.

For more information, see What is a Chat 2 Pay Sandbox configuration.
