Braintree Sandbox Test Cards
Official sandbox cards for Braintree GraphQL API and Drop-in UI integration testing across Visa, Mastercard, and American Express.
| Scenario / Test Goal | Test Card Number | Expiry | CVV | Expected Result | Verification |
|---|---|---|---|---|---|
Valid sandbox card (Visa) | 4111 1111 1111 1111 | Any future date | 123 | Does not itself trigger a card verification error. Transaction outcome depends on the test amount and any enabled AVS or CVV rules. | Verified against official sourceRecorded: 2026-09-29Re-verified against the linked official provider documentation on 2026-09-29. |
Valid sandbox card (Mastercard) | 5555 5555 5555 4444 | Any future date | 123 | Does not itself trigger a card verification error. Transaction outcome depends on the test amount and any enabled AVS or CVV rules. | Verified against official sourceRecorded: 2026-09-29Re-verified against the linked official provider documentation on 2026-09-29. |
Valid sandbox card (American Express) | 3782 822463 10005 | Any future date | 1234 | Does not itself trigger a card verification error. Transaction outcome depends on the test amount and any enabled AVS or CVV rules. | Verified against official sourceRecorded: 2026-09-29Re-verified against the linked official provider documentation on 2026-09-29. |
Processor declined (Visa) | 4000 1111 1111 1115 | Any future date | 123 | Processor declined verification response. | Verified against official sourceRecorded: 2026-09-29Re-verified against the linked official provider documentation on 2026-09-29. |

Using Braintree Sandbox Cards in Development
Braintree Sandbox supports testing credit card tokenization, authorization, and processor decline simulation via Braintree GraphQL API, SDKs, and Drop-in UI.
1. Initialize with Sandbox Keys
Obtain your Sandbox Merchant ID, Public Key, and Private Key from the Braintree Sandbox Control Panel. Set your gateway environment configuration explicitly to Environment.Sandbox.
2. Enter Test Card Credentials
Use official sandbox card numbers from the table above. Expiration dates accept any future date. Use a scheme-appropriate CVV format (for example, three digits for Visa/Mastercard and four for Amex); enabled AVS/CVV rules and the test amount can also affect the result.
3. Test Tokenization & Nonce Generation
In client-side implementations (Drop-in UI or Hosted Fields), test cards tokenize successfully to return a paymentMethodNonce for server-side processing.
4. Simulate Card Verification & Processor Declines
Use designated Braintree test card numbers such as the Visa ending 1115 or Mastercard ending 5100 to simulate unsuccessful card-verification responses. For transaction-level decline testing, Braintree also uses test transaction amounts to trigger processor responses.
