If you import inquireis inquiries Beds24 will create a request booking. If the request turns into a confirmed booking the status will automatically change. If you want to automatically cancel requests which do not turn into confirmed bookings you can set up an [[Auto_Actions|Auto Action]] to automatically cancel the booking after a certain period.
Depreciated setting :- If you go to {{#fas:cog}} (SETTINGS) >PROPERTIES > BOOKING RULES and do not see setting 'REQUEST BOOKINGS' the option is not available for your account. If you import inquiries you should set "Bookings with Request Status to "Do not block the room" in {{#fas:cog}} (SETTINGS) >PROPERTIES > BOOKING RULES so the room does not get blocked in Airbnb. If you block the room Airbnb will lock it. In this case , the inquiry will be imported with the status "Cancelled" so it can convert to a confirmed booking.
