## Sandbox Testing {#sandbox-testing}

The Sandbox server returns simulated responses, enabling you to try this API quickly, and should not be used for full integration testing. For valid test card numbers that you can use in your requests, see [Sandbox Test Cards](https://developer.mastercard.com/mastercard-send/documentation/implementation/sandbox-test-cards/).

### Test Scenarios {#test-scenarios}

Use the following test scenarios to produce specific responses. As long as the request message is properly formatted, a valid response will be returned.

|             Test Scenario             |                  Test Data                   | HTTP Status Code/Reason Code |                 Expected Result                  |

## MTF Testing {#mtf-testing}

### Test Card Numbers and Associated Networks {#test-card-numbers-and-associated-networks}

For test card numbers that you can use for testing in the MTF environment, see [MTF Test Cards](https://developer.mastercard.com/mastercard-send/documentation/implementation/test-cards/).

Do not use consumer card numbers in the test environment.

### Sample Data {#sample-data}

| Mastercard | first_name: Dicky, last_name: Bird | pan:{test-account};exp=2077-12;cvc=234 *See below* | line1: 1 Main Street, line2: Apartment 11, city: HAGEN, country_subdivision: MT, postal_code: 63368-3784, country: USA | *See below (Expected Results)*                                    |

For {test-account}, you can use the following Mastercard test account numbers to get success responses with different response values. Specify the account number in the Account URI field using the pan schema, for example `pan:5204740000004501;exp=2077-12;cvc=234`.
