API in Hotel Technology

What is an API in hotel technology?

An API (Application Programming Interface) is a software interface that allows different hotel systems to communicate and share data automatically.

In the hotel business, APIs can connect tools like the PMS, CRM, Channel Manager, Booking Engine, and guest communication platforms, eliminating the need for manual data entry and duplicate updates.

How does it work in a hotel?

APIs are vital for creating an integrated tech ecosystem for hotels. For example, when a booking is made, an API can instantly update room availability in the PMS and Channel Manager.

APIs also enable automated guest messaging, real-time pricing updates, and live performance reporting. They reduce human error, save staff time, and improve the guest experience by providing faster and more personalised service.

Key Insight

APIs are the backbone that connects different software systems so they operate as one unified ecosystem. Open APIs are now standard in modern hospitality technology, allowing hotels to mix and match the best tools for their specific needs.

Guest Journey Mapping

It identifies all touchpoints — from booking and check-in to feedback after guests have stayed — to understand how guests interact with the hotel and how their experience can be improved.

Guest Feedback

Guest feedback is information provided by hotel guests about their experience before, during, or after a stay. It includes opinions on things like how good the service is, how comfortable the rooms are, what amenities are available, how clean the hotel is, and how satisfied guests are.
