Stripe Test Card Numbers

Stripe provides test card numbers that simulate real payment scenarios in test mode. These cards only work when your Stripe integration is running with test API keys (prefixed with sk_test_). No real charges are made and no real money is moved.

To use a test card, enter the card number in a Stripe-powered checkout form. Use any future expiration date (e.g., 12/34), any 3-digit CVC (4 digits for Amex), and any 5-digit ZIP code. The card will behave according to its designated scenario.

Testing Best Practices

• Test the happy path first. Use 4242 4242 4242 4242 to confirm your checkout flow works end-to-end before testing error scenarios.
• Test every error your users might encounter. Declined cards, insufficient funds, and expired cards are the most common failure modes.
• Verify 3D Secure handling. If you accept international payments, Strong Customer Authentication (SCA) is mandatory in the EU. Test both successful and failed authentication flows.
• Test dispute flows. Use dispute-triggering cards to ensure your system handles chargebacks gracefully and sends appropriate notifications.
• Test international cards. Different countries may trigger different Stripe behaviors, including currency conversion and regional card network routing.

Testing Affiliate Payments with Stripe

When building an affiliate program that integrates with Stripe, you need to test the full conversion flow: click tracking, checkout, webhook processing, and commission attribution. Use the successful payment cards above to simulate real purchases in test mode, then verify that commissions are correctly calculated and attributed to the referring affiliate.

Refgrow integrates directly with Stripe webhooks to automatically track conversions, calculate commissions, and manage payouts. Test your entire affiliate pipeline with these cards before going live.
