When you connect your accommodation with Booking.com through Channel PRO, certain alerts may appear. Far from being a problem, these are notifications that help you detect what information is missing or what settings you need to review for the connection to work smoothly. Knowing these messages and how to resolve them will save you time and potential frustration.

Frequently asked questions
What happens if I don't resolve an alert?
The accommodation will not be published or will remain blocked until you complete the required information.
Can I ignore an alert if I have already submitted the information elsewhere?
No. The alert indicates that Booking.com has not received that data through the connection. You must add it in the Avantio listing or configuration.
Why does the alert repeat after correcting the data?
It may be because the changes have not yet synced. Wait a few minutes and check again.
Do alerts affect already confirmed bookings?
No. Existing bookings are not affected, but the publication of future availability may be blocked.
