Can I book more than one room at a time for a family or a group through your hotel booking API?

Yes, in most cases you can search for and book several rooms together in one go. When you run the search you tell the system how many rooms you need and how many adults and children are staying in each one, and the results come back priced for the whole stay rather than for a single room. For children you will usually need to enter their ages, because many hotels decide whether a child stays free, needs an extra bed, or counts as an adult based on age, and the correct price only comes through if that information is entered properly.

There are limits, and they come from the supplier rather than from us. Most hotel suppliers allow only a certain number of rooms in one booking, and if your group is larger than that you may need to split it across more than one booking or handle it as a proper group enquiry with the hotel or supplier directly. You should also expect that not every room type will have the same availability, so a family wanting identical rooms next to each other is a request rather than something the booking can guarantee.

It also varies whether a multiple room booking comes back as one reference or as separate references for each room, and the cancellation rules can apply to each room on its own. That matters when a customer later wants to drop one room and keep the rest, because in some cases that is a straightforward partial cancellation and in others the whole booking has to be cancelled and rebooked at whatever price is then live.

Before you quote a group, run a test search for the same room count in your portal and read the room and cancellation details that come back, so you know exactly what you are promising the customer.
