Question 2

How does OnSeason connect to my property management system?

Accepted Answer

Via a single API key. You enter your PMS credentials once in the OnSeason dashboard, and Calry's unified API handles the connection - syncing your property listings, live availability, rates, and reservations in real time. No migration, no manual setup, no technical skills required.

Question 3

What PMS data does OnSeason sync in real time?

Accepted Answer

OnSeason syncs property listings (descriptions, photos, amenities, policies), live availability calendars, dynamic rates, minimum stay rules, and new, modified, and cancelled reservations - all via real-time webhooks. Your direct booking website always reflects the same data as your PMS, with no manual updates needed.

Question 4

What is Calry and how does it power OnSeason's integrations?

Accepted Answer

Calry is OnSeason's unified PMS API platform - the infrastructure layer that connects OnSeason to 40+ property management systems through a single, standardized integration. Instead of building separate integrations for each PMS, Calry provides a common data model, managed authentication, and real-time webhooks for the entire ecosystem. It's also available to third-party developers at calry.app.

Question 5

Will my PMS calendar be out of sync if I add OnSeason?

Accepted Answer

No. OnSeason uses real-time webhook sync via Calry - meaning availability changes in your PMS (new bookings, cancellations, blocked dates) are reflected on your OnSeason direct booking website within seconds. There is no polling delay and no risk of double bookings from the direct channel.

Question 6

Can I use OnSeason without changing my current PMS?

Accepted Answer

Yes. OnSeason is designed to work alongside your existing PMS, not replace it. Your PMS remains the source of truth for your operations. OnSeason simply reads your PMS data (availability, rates, listings) and adds a direct booking channel on top - zero disruption to your existing workflow.
