RapidCents provides a set of test card numbers to simulate payment scenarios in test mode, without processing actual payments or charges. When entering a test card number, you can use any future expiration date and any three-digit CVC code to simulate a successful payment. To simulate a failed payment, use the specific test card numbers and CVC codes provided by RapidCents.

It is essential to note that these test card numbers are only valid in test mode and should not be used for real payments.
