What Is PMS Integration?
A PMS integration is a connection between a hotel's property management system (PMS) and another software application, so the two share information automatically. Most PMS integrations run over an application programming interface, or API (PMS integrations (Cloudbeds Articles)) (What are PMS integrations and why are they important? (Mews blog, 2026)).

How PMS integration works
Integrations link the property management system to the other tools a property runs. Common connections include channel managers, revenue management systems, point-of-sale (POS) systems, customer relationship management (CRM) tools, payment gateways and keycard systems (What are PMS integrations and why are they important? (Mews blog, 2026)). A 2025 Starfleet Research survey, sponsored by IBS Software, counted the PMS, revenue management, POS, booking, distribution and loyalty among a hotel's core systems (Research: Fewer Than One in Four Hotels Have Fully Integrated Core Systems (Hospitality Net, 2025)). Each connection moves data in one of two patterns: a one-way integration sends data in a single direction, and a two-way integration moves data both ways (PMS integrations (Cloudbeds Articles)).
What a PMS can connect to depends on the interfaces its provider makes available. In 2021, Oracle published the specifications for its hospitality REST APIs on GitHub, giving partners secure access to more than 3,000 API capabilities, and said there was no longer a mandatory certification process (Oracle Opens Hospitality API Specifications to Help Industry Recover (Oracle, 2021)). Two years later, in June 2023, Oracle reported that more than 700 partners had built or were actively building integrations with its OPERA Cloud platform, with new integrations up 75% over 12 months (Oracle Cloud Drives Hotel Industry Automation and Efficiency with New Integrations (Hospitality Net, 2023)).
Why PMS integration matters for hotel distribution
Booking.com does not accept direct connections from individual properties, which connect through a channel manager instead, and it has paused integrations with new connectivity providers until further notice. Through those connections, providers list properties and sync rates and availability (Booking.com Connectivity). Airbnb's API guide for hosts in Australia and New Zealand says all rates and availability on Airbnb are pushed through the host's channel manager (Airbnb API FAQ guide (Airbnb)). For properties on those two channels, the PMS integration that carries distribution data is the one with the channel manager.
Fully connected systems are still the exception. In the Starfleet Research survey of more than 250 hotel IT decision makers, only 24% of hotels reported full integration of their core systems (Research: Fewer Than One in Four Hotels Have Fully Integrated Core Systems (Hospitality Net, 2025)). In the 2026 Hotel Technology Outlook, a study of more than 300 hotel professionals by the NYU Jonathan Tisch Center of Hospitality with Stayntouch and IDeaS, 38% named integration as a top pain point (2026 Hotel Technology Outlook Report (Hotel Tech Report, 2025)).
PMS integration compared with channel managers and interface standards
Industry standards try to cut the cost of building every connection from scratch. HTNG Express, launched in 2022 by Hapi and the American Hotel and Lodging Association (AHLA), is a single standard for a simple one-way PMS data feed that can be executed in under a week; a workgroup of more than 50 hotel IT leaders and technology providers built it (Hapi, AHLA Launch HTNG Express to Accelerate Innovation (Hospitality Net, 2022)).
| PMS integration | Channel manager | Interface standard (such as HTNG Express) | |
|---|---|---|---|
| What it is | One link between the PMS and one other application, built for that pair | Software that carries a property's rates and availability to booking channels | One shared specification that many providers can build to |
| Direction | One-way or two-way, depending on the build | Out to channels such as Booking.com and Airbnb | HTNG Express covers a one-way PMS feed |
| Typical examples | Revenue management, POS, CRM, payments, keycards | Listing properties, syncing rates and availability | POS to PMS guest lookups, simple PMS data feeds |
