Will my customer get a hotel voucher they can show at the front desk when they arrive?

Yes. Once a hotel booking is confirmed through the API, the confirmation comes back with everything the hotel needs, and your portal turns that into a voucher your customer can download or receive by email. It normally carries the guest names, the hotel name and address, the check in and check out dates, the room type, what meals are included if any, and the reference the hotel or the supplier uses to find the booking.

The voucher goes out in your own branding, with your agency name on it, and the supplier sitting behind the booking is not shown to your customer. The reference printed on it is usually the supplier's booking reference, because that is the one the hotel can actually look up in its own system. Your own internal booking number can sit alongside it, but it is the supplier reference that the front desk will ask for if there is any confusion.

There are a few honest limits here. A small number of hotels only accept the voucher in the supplier's own format, so what your customer receives may look slightly different for those properties. If a booking is one that has to be requested rather than confirmed straight away, no voucher exists until the hotel accepts it, so nothing should be sent to the customer before then. Very occasionally the hotel takes a little while to see the reservation on its side, and the reference is what sorts that out.

Before you go live, make one test booking on your portal and look at the voucher yourself, so you know exactly what your customers will be holding when they walk in.
