Hotel technology

API

An API is the door through which two programs talk and pass data with no human in the middle. In a hotel it is what lets the PMS, the booking engine and the channel manager share availability instantly. When a vendor has no good API, the integration is done by hand and that is where money leaks.

Example Thanks to the API, a booking made on the website shows up in the PMS by itself a second later.

FAQ

What is an API in the hotel industry?
An API is a software bridge that lets two programs exchange data automatically. For instance, it connects a hotel's PMS to its booking engine to sync room availability instantly.
How does an API work between a hotel and its sales channels?
The API sends structured data like rates and availability from the channel manager to platforms such as Booking or Expedia. When a guest books, the API updates inventory across all connected systems within seconds.
Why does a good API matter more than manual integration?
A strong API prevents human errors and saves hours of manual work. Without it, hotel staff must update availability on each portal separately, leading to overbookings and lost revenue.
