Please ensure that the expiry dates on your active subscriptions are valid and up-to-date, as some issuers may decline cards with outdated card expiry dates. These can be updated manually by using either MyST or by submitting a TRANSACTIONUPDATE request using our Webservices API.
If you are processing high volume transactions, we recommend enabling Scheme updates, which automatically keeps payment credentials up-to-date. Click here to learn more.
