If a customer payment fails, they will be asked to try again. Typical reasons for a payment failing include errors with entering the card number, expiry date or CVC number, or potentially even a connection issue. These issues can usually be resolved when the customer tries to enter the payment for the second time. Another reason for a payment being declined or failing is that the Payment Links function may be temporarily unavailable. In the rare event of this occurring, the customer would see a notification advising that this method of payment is currently unavailable. They would then need to make their payment by bank transfer instead.
