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.

The cost of Expedia Rapid API varies for each partner. It’s dependent on market, coverage, and booking volumes.
How to apply
Expedia, a market leader, is selective with partner integrations, favoring larger businesses over startups due to the engineering resources required. The process from contract negotiation to API connection can take months.
This API lets you send and retrieve data for the content available on Booking.com, one of the largest and most popular online travel agencies. It's a great solution for businesses seeking to incorporate Booking.com's vast array of accommodation options into their own platforms or services.
Their inventory includes around 400,000 establishments such as hotels, motels, and resorts, as well as 2.3 million homes and apartments. These properties span more than 220 countries and the platform is accessible in more than 40 languages.
Like many other APIs providers, Booking.com discusses pricing options only after you sign up with them.
How to apply
Access is granted exclusively to Connectivity partners, meaning you need Booking.com approval first. Submit your details through the online form to see whether you qualify. Once you've completed the form, Booking.com may request specific documents, agreements, checklists, and account information from your company. Do note that Booking.com has temporarily halted integrations with new Connectivity providers, but they plan to reopen the process soon.
Priceline Hotel API
When Priceline came into existence in 1998, it aimed initially at helping people book unsold airplane tickets. They’ve now broadened their services to include car rentals, cruises and accommodations.

These rates, which are available to B2B partners and membership groups, or as part of a bundled product, apply to more than 70,000 properties across the globe.
Priceline maintains a veil of secrecy on their pricing conditions. You'll only know them after you apply to work with them.

Becoming a Priceline partner begins with a simple application process. You’ll need to fill out the form on their website with your company details, then wait for their team to review it. They’ll get back to you with their decision or any further questions.

What is a hotel booking API?
A hotel booking API is a tool that enables different software applications to communicate with each other, simplifying the process of booking hotel rooms. These APIs are typically provided by online travel agencies (OTAs), hotel aggregators, and individual hotel chains.
How does a hotel booking API work?
A hotel booking API works by facilitating the exchange of data between different systems. When a user enters their desired hotel details, such as location and dates, on a website or app, the booking platform sends a request to the hotel booking API. The API processes the request and retrieves real-time or cached data on hotel information, availability, and pricing.
What should I consider when choosing an online hotel booking API provider?
When choosing a hotel booking API provider, consider the scale of their inventory, ease of API integration, and number of properties. Budget is also key, as each provider has a different pricing strategy. If you're an OTA or travel company, think about the provider's geographic coverage, languages they support, and their approval process. Remember, the best provider depends on your company's unique needs and goals.
