The most important thing first

CASY is not connected directly, but via an external channel manager to Booking.com. This keeps reservations, availabilities and, depending on the interface, prices synchronized between Booking.com and CASY. In daily use, this reduces manual entry and simplifies online channel management.

For hotels, resorts and apartments this separation is practical because each system keeps its clearly defined role. We at Casy Software Solutions Sagl rely on the connection via a channel manager so that operations are not burdened with individual maintenance on booking portals.

How does the integration from Booking.com to CASY work?

In day-to-day business, bookings come in via Booking.com, are transmitted to CASY via the channel manager and processed further in hotel operations. At the same time, remaining room availability is updated through the connection. Depending on the interface used and setup, prices can also be transmitted to Booking.com.

  1. A guest books on Booking.com.
  2. The reservation is transmitted to CASY via the channel manager.
  3. Availability is updated between the systems.
  4. Prices can also be transmitted depending on the interface.
  5. Reservations and portals need to be manually maintained significantly less often.

Why is a channel manager useful for CASY?

From our experience: the greatest benefit lies not only in the connection itself but in the relief it provides in everyday life. When reservations arrive automatically and availabilities are synchronized, the effort for manual follow-up decreases noticeably.

How to set up the connection?

First, determine which external Channel Manager is suitable for your operation and the CASY integration. Then apply for the connection in the Booking.com extranet and obtain confirmation from the provider. Subsequently, room categories and rates are allocated between the systems.

  • Choose a suitable Channel Manager for the operation
  • Apply for the connection in the Booking.com extranet
  • Wait for provider confirmation
  • Allocate room categories and rates
  • Check prices, availabilities and reservations before go-live

What to pay attention to before go-live

Before launch, carefully check prices, availabilities and the transfer of reservations. This prevents incorrect allotments or misassignments between room categories and rates.
