Test Cards

In sandbox environment, we offer generic merchant accounts that are useful for testing functional integration. Some processors behave slightly different depending on the settings on the live merchant, so we always advice a full end to end test on your live merchant account, before going live.

Matching Rules

Test cases are matched using a best match first approach. The system finds the rule that matches the most input fields:

  1. If both the card number and CVV match a specific rule, that rule is used.
  2. If the card number matches but the CVV does not match any specific rule, the catch-all (any) rule for that card is used instead.

For example, sending CVV 200 with the Visa card 4012000098765439 matches both the card number and CVV of a specific decline rule — so you get a decline. Sending CVV 123 matches only the card number, so the catch-all success rule applies.

Recurring (Rebill) Test Cards

To test failures on recurring transactions specifically, use the CVV trigger codes 300 and 301. Unlike 200/201, these approve the initial sale or authorization and only decline when the card is later rebilled — that is, on a subsequent transaction that references the original via the stored credential. This lets you simulate a subscription that activates successfully but fails on a later renewal.
