If a request-to-book reservation in Guesty shows no card on file, make card collection part of your acceptance routine and have the guest add a card before you approve the request.
- Open the reservation in Guesty.
- On the Payments tab, use Request payment method to have the guest add a working card.
- Approve the request once a card is on file.
Why approve after the card is added. This catches the problem while the guest is still engaged, instead of after the request is accepted and the dates are blocked.
