Travel APIs: a complete list of inventory providers

Oct 14, 2024 • 24 min read
When you've decided your business is ready for a travel API integration, the next question is: which API should you choose?
Scrolling through so many options is far too time-consuming, boring, and ineffective, which is why we at Zoftify decided to help you out and compiled a list of the best travel APIs based on different business needs.
How to use this guide
We've made a guide to help you find the right travel APIs for your business. The APIs are sorted by what they offer — from hotel booking APIs to flights, car rentals, tours, and more. We've laid it out in a way that makes sense, so you can easily find what you need using the menu on the left.
We've included prices where we can, but some companies prefer to discuss this directly with partners. The same goes for travel APIs guides — we've linked them when they're public, but some you'll need to ask for.
