Payment Provider Test Cards
This page is a reference guide for sandbox payment testing. It consolidates curated test card scenarios for Stripe, Adyen, Checkout.com, and Airwallex so developers, QA engineers, and payment teams can simulate successful authorizations, 3DS flows, response-code failures, AVS/CVC checks, and amount-triggered edge cases without relying on scattered provider documentation.
How to use these test cards
- Use provider sandbox environments only. The same card number can behave differently between PSPs, so always match the card to the provider shown.
- Pay attention to trigger fields. Some scenarios require a specific amount, AVS input, CVC response, or 3DS action to reproduce the documented outcome.
- Treat this page as a reference layer. For final behavior, response codes, and test flow nuances, validate against the linked official provider docs.
