Your Guesty property is assigned to the Booking Engine API distribution channel, but it still does not appear on your website.
Why this happens. Two settings in Guesty must both be active for a property to flow through the API connection. The property must be assigned to the Booking Engine API distribution channel, and the property itself must have List on booking channels toggled on. If the property page shows that it is not connected to any channels, that toggle is the missing piece.
What to do. Turn on List on booking channels for the property in Guesty. Once both settings are enabled, the listing comes through on the next sync and displays on your site.
