Test Cards are used to simulate transactions and receive response codes in the sandbox environment. Test cards are provided for simulating both successful and failed transactions. This enables a developer to test all transactions types prior to going live.
Test cards can only be used in the sandbox or when using test mode (mode 0) in the live environment. If you use a test card in Mode (1) in the live environment you will receive an error response.
Test cards are provided for:
- Diners cards
