OTA channel sync
OTA channel sync is the bi-directional exchange of availability and bookings between a rental's system and online travel agencies such as Rentalcars, Discover Cars or AutoEurope. It prevents overbooking and lets you sell across multiple channels at once.
Definition
OTA (Online Travel Agency) channel sync keeps fleet availability consistent between the rental's system and external sales channels such as Rentalcars, Discover Cars or AutoEurope. Any booking on any channel immediately reduces availability on the others, with no overbooking.
How it works
Architecture: the rental system holds the single source of truth for fleet availability. OTAs talk through REST API or webhooks: 1) New booking on Rentalcars → webhook to the system → decrement availability → push to Discover Cars + AutoEurope. 2) Cancellation on Discover Cars → webhook → restore availability → push to all channels. 3) Price change in the rental panel → batch push to every channel.
Why it matters for a rental company
Without sync: manual availability updates per channel, and overbooking creeps in during peak season. With sync: no cross-channel overbooking, more channels = more bookings, and less manual work keeping availability up to date.
What OneRental does
In OneRental one shared availability covers bookings from your booking site and widgets and the ones staff enter in the app (phone, desk), so those channels can't double-book. Staff enter bookings from other platforms by hand, and the system makes sure they don't clash with the rest. From the Growth plan you also get calendar feeds (iCal), read-only. If a platform can import a calendar from a link, as Airbnb, Booking.com and some charter platforms can, give it a “Busy only” feed and it blocks the dates you've already sold in OneRental. In that feed each booking shows only the vehicle and “Reserved”, with no customer data.
