To ensure a consistent payments experience for Clover merchants, integrations must be tested and validated. Part of the testing process is verifying all payment flows for the region where a merchant does business. Laws and regulations may affect the types of transactions a merchant can perform, so developers should complete the tests for every region where their integrated app will be used.
Tests must be conducted using a DevKit configured for the sandbox environment. The test card numbers used for some tests will only return the correct responses in sandbox.
