Cardholder entering wrong card details
The Make payment button will turn on only if the cardholder types the correct card details as CCPCI is doing a background check while the details are being typed. An error message will be displayed in case the card details are not correct.
Cardholder can retype the card details, no need to create a new link, but you need to consider the expiration time of the payment link and if needed, create a new one and send it to the cardholder.
