# About the Demand API

**Bring Booking.com travel services into your application.**

The Demand API helps you offer Booking.com travel options through your platform.

Choose how much of the traveller journey you want to manage: display travel content, support search and comparison, enable bookings where available, or direct travellers to Booking.com to complete their booking.

You can integrate accommodation, car rental and attraction services. Transfer search is available in Beta, and you can add shared services as your integration grows.

## Choose an integration flow

Choose the flow that fits your application and business model. The available flows depend on the travel service and your partner access.
