Run the classification test cards

Eight sandbox test cards each classify as something specific, so you can see how the platform labels a card before a real one arrives.

    What to build

    Work through the scenario for the card types your merchants take. Each one gives the request to send and the classification to expect in the response's card data. The classification comes from the whole card number, so send the number exactly as published.

    What this means for PCI

    This is guidance rather than a compliance determination. Which questionnaire you are eligible for depends on your full environment, so confirm it with your QSA or your acquirer before you rely on it.

    Worth knowing

    • The card decides the classification, not the outcome. Approval and decline still come from the amount, except on the EBT card, which takes no amount trigger.
