The test gateway exists only in sandbox. It needs no credentials and never contacts a real processor: each answer comes from the card number, using the test card list.
- Ordinary test cards are approved, with an authorization code, AVS
Ywhen a postal code was sent and CVVMwhen a security code was sent. - Decline cards are declined with their documented code.
- Cards marked “capture fails” or “refund fails” succeed first and fail on the later step.
- The security code
000is always incorrect, and a past expiry date is always declined as expired. - Captures, voids and refunds only work on transactions the test gateway made.
- A 3-D Secure result is recorded with
forwardedset totrueand never changes the answer.
Surcharging works on the test gateway as on NMI or Authorize.net: OrderCard adds the rate you set on the gateway.
