How to use Mollie test cards
- Switch your Mollie integration to its test or sandbox environment and use test credentials. Live credentials reject these numbers.
- Enter a card number from the tables above. Expiry: Any. Security code: Any.
- Start with a successful card to confirm the happy path, then work through the decline and error cards so every failure message in your checkout gets exercised.
- Use the trigger values (failure reasons by amount) to simulate outcomes that are not tied to a card number.
