Can I book a multi city flight itinerary for a corporate client who is visiting three cities on one trip?

Yes, multi city flight bookings can be made through a flight booking API in most cases, and the search form on your portal can be set up to collect several separate legs with their own dates and airports. Your customer or your staff member enters each leg, the search goes out to the suppliers connected to your account, and the results come back as one combined itinerary with one total fare where the supplier is able to price it that way.

How well this works does depend on the supplier behind the search. Full service airlines and the global distribution systems handle multi city itineraries natively, so you usually get a single booking reference covering the whole trip. Many low cost carriers do not support true multi city pricing, so the system has to build the trip out of separate one way bookings instead. That still gets your client where they need to go, but it means more than one booking reference, separate baggage allowances, and separate change and cancellation rules for each leg, which is worth explaining to the client before they pay.

There are a few other limits to be aware of. The number of legs you can request in one search is set by the supplier, and some will not combine airlines that have no agreement with each other. If one leg has to be changed later, a single combined ticket often has to be repriced as a whole rather than leg by leg, and what that costs is decided by the airline fare rules, not by us.

Before you promise this to a corporate account, check which of the flight suppliers on your plan support combined multi city pricing and run a practice search for a typical three city trip so you can see exactly what your staff and your client will be shown.
