What is a hotel booking API?

A hotel booking API, or Application Programming Interface, is a set of rules and protocols used to allow different software applications to communicate with each other. When a developer integrates a hotel booking API into a travel app or website, travel agents and customers gain access to a broad range of hotel options, making the booking experience more streamlined, efficient, and convenient.

Here's how it works: when a user enters their request for a hotel on a third-party website (and selects their preferences on things like location, check-in date, and duration of stay), the booking platform sends an API request to the data providers. This returns real-time (sometimes cached) data on hotel information, availability, pricing, and more. Think of the API as a bridge, connecting users with the necessary hotel information.
