Problem #

You see one of the following errors while attempting to process payments with the WorldPay payment gateway module:

You have not configured a payment response password.

Your payment response password does not match.

Cause #

Your WorldPay account configuration does not currently include the required Payment Response Password value, or the value in WHMCS does not match the value in your WorldPay account.

Solution #

To resolve this error, add the Payment Response Password value that displays at Configuration () > System Settings > Payment Gateways to your WorldPay account.

If you have already set this value, check to ensure that it matches the value in the WorldPay control panel.
