Use these test cards to simulate the outcome of a one-time card payment in sandbox.

How to use test cards

Enter a test card in the sandbox dashboard’s card payment form.
  • Use any future expiration date and any three-digit CVC.
  • Complete the required cardholder and billing details.
  • Use one of the card numbers below. Other card numbers are rejected.

Successful payments

Use these cards to test an accepted payment. Funds become available to the merchant after you simulate settlement.

Declined payments

Use these cards to test issuer declines. A declined payment fails without moving money. You can retry an open payment intent with a success card. After five issuer declines, the intent closes. A non-test card does not count toward that limit. If Natural cannot verify a card’s fixture identity, the request returns an error without creating a payment attempt; retry the request.
