In order to simulate payment errors in PayPal sandbox mode, you can utilize specific test card numbers provided by PayPal. This allows you to check for various decline scenarios.
For testing payment declines such as insufficient funds or expired cards, you can invoke corresponding test card numbers during checkout. For instance, using a card marked as expired triggers an expiration error.
Make sure to handle different error scenarios through the onApprove and onError methods effectively to capture payment decline messages and display them to users appropriately.
Refer to the PayPal Developer documentation for a comprehensive list of test credit card numbers to simulate various error conditions, enabling rigorous testing of your payment flow.
