Use Braintree sandbox credentials and a future expiry date. CVV 123 (1234 for Amex) gives a matching CVV response. Transaction amounts and your AVS/CVV rules also affect payment results.

To test payment responses, use amount 10.00 for authorization, 2000.00 for a processor decline or 3000.00 for a processor failure. These amounts apply regardless of currency. See amount and AVS/CVV rules
