In order to push your property to the right Booking.com account we need your legal entity ID which only group accounts have. This is a special ID which is not your Booking.com hotel partner ID or hotel ID.
*Check for your legal entity ID. If you do not have it ask Booking.com support to give it to youor contact us via a support ticket.
*Start a support ticket via the SUPPORT button in the top left of your control panel with your legal entity ID. We will then prepare the connection for you.
