This method returns a list of reservations not marked as synced.
After the user calls this method and takes appropriate action then they must use the Sync Reservation API method to mark each reservation as synced.
The body of each reservation can be retrieved using the Reservation API method.
The reservation list is unique per Hotelier API Account. This means that each API account, even for the same property, have independent sync state.
WebHotelier supports real-time reservation notifications.
If possible, use PING instead of calling this method on schedule or just use PUSH instead.
This method is only accessible using a Hotelier API account.
You MUST not call this method more often than every 5 minutes.
This method MUST not be called simultaneusly by more that one thread or process for the same property, to avoid unexpected result. WebHotelier does not enforce this requirement.
Multiple threads reading the same list of pending reservations may result in duplicate reservations on your system.
Repeated failure of marking reservations as synced can result in a ban of your API account or your IP address.
