If a hotel cancels my customer's booking after I have confirmed it, will I find out in time to rebook them?

Yes, in most cases you will find out, though how fast the news reaches you depends on the supplier rather than on your portal. A hotel booking that comes through an API keeps a status against it, and when the supplier tells us the room has been rejected or released, that status changes and the booking stops showing as confirmed. You can set the system up so a change like that raises an alert for your team instead of sitting quietly in a list that nobody opens.

The honest limit is that suppliers behave differently. Some send an automatic message the moment a hotel refuses or releases a room, and those cases reach you within minutes. Others only update their own record and expect your system to ask them again, so the change appears at the next check rather than straight away. A small number still rely on an ordinary email to your agency, and in that situation the portal cannot know about it until somebody reads the message and updates the booking by hand.

When it does happen, the system will not quietly rebook the guest for you. You search again, make a fresh booking, and raise the refund or credit against the original one so your accounts stay straight. Keeping the guest informed is still your call, which most agencies prefer, because they would rather explain the change themselves than let an automatic message do it.

Before you go live, ask which of your chosen suppliers send status updates automatically, and get into the habit of reviewing bookings a few days before arrival for anything made a long way in advance.
