A guest may book on your website without paying and still receive automated messages from Guesty, such as the pre-check-in link and guidebook.
Why this happens. Guesty sends automated messages when a reservation is confirmed, regardless of whether the guest has paid.
Holding messages until payment. In Guesty, open each automated message that contains access details or property information, and add the message condition Reservation was fully paid. Guesty then waits until payment is received before sending the message. This is a Guesty setting and requires no changes on your website. Guesty’s troubleshooting article covers this in detail: https://help.guesty.com/hc/en-gb/articles/9390837261341-Troubleshooting-Automated-message-sent-to-an-unpaid-reservation
Preventing unpaid bookings. To prevent the unpaid booking from being created in the first place, look into enabling Stripe pre-authorization at checkout.
