Sync Airbnb, Booking and Vrbo with Elvestay via iCal (no overbooking)

Q: Does iCal sync completely prevent overbooking?

It drastically reduces the risk by automatically blocking booked dates across all connected channels. Because iCal syncs periodically rather than instantly, a very brief window can exist between a new booking and the next sync. To minimise it, connect all your calendars from the start and avoid accepting manual bookings without first checking actual availability across your channels.

Q: Do I need an API integration with each portal?

No. Elvestay's sync uses iCal, the open RFC 5545 standard, not each platform's proprietary APIs. You only need the calendar URL that Airbnb, Booking and Vrbo provide in your listing settings, and to import it into Elvestay. It is a universal, straightforward method compatible with virtually any rental platform that exports calendars.

Q: How often does the sync update?

Elvestay synchronises periodically, several times a day, through an automated process that checks the external calendars and applies changes. It requires no action on your part once your listings are connected. Bear in mind that iCal works by periodic polling, so availability changes may take a little while to propagate across all channels.

Q: Is it safe to share my iCal URL?

Yes. Elvestay's iCal URLs include a unique token, and if you ever believe your link has leaked you can rotate it: a new URL is generated and the old one stops working. We also apply anti-SSRF protection when importing external URLs to prevent improper access to internal resources. Only share your links with the platforms where you list.

Q: Can I manage syncing for several properties?

Yes. Management is per listing: each property has its own calendar section with its import and export iCal URLs. This lets you connect and control each property independently, with its own links to Airbnb, Booking and Vrbo. If you manage several properties, simply repeat the connection process in each listing's calendar.

If you list your property on several platforms, overbooking is a constant threat. With Elvestay's iCal sync you keep a single reliable calendar and avoid double bookings, cancellations and penalties.

Why sync your calendars

When you list the same property on Airbnb, Booking, Vrbo and Elvestay, each platform manages its own calendar. Without synchronisation, all it takes is two guests booking the same dates on different channels for you to end up with an overbooking. And a double booking is not just an awkward call: it means cancelling on someone, refunding money, taking on penalties and risking your reputation and ranking on every portal. Syncing your calendars removes that risk. You keep a single reliable calendar in which any date booked on any channel is blocked on all the others. You gain peace of mind, cut the manual work of updating availability one by one, and deliver a flawless experience to your guests.

How iCal sync works at Elvestay

Synchronisation relies on iCal, the open RFC 5545 standard that almost every rental platform uses to share availability. Each portal publishes a calendar URL containing your booked dates, and that same technology lets systems understand one another without depending on proprietary integrations. At Elvestay it works both ways. You import the iCal URL from each platform and we automatically block the dates already booked on your listing. At the same time, Elvestay generates your own iCal URL so the other portals can import your Elvestay availability. This two-way sync keeps all your calendars aligned, importing and exporting bookings continuously.

Connect Airbnb, Booking and Vrbo step by step

The connection is managed per listing. Each Elvestay listing has its own calendar section with its iCal URLs, so you control each property independently. First, copy the export iCal URL from Airbnb, Booking and Vrbo (each platform offers it in your listing's calendar settings). Then paste it into the calendar section of the matching listing in Elvestay to import those dates. Finally, copy the iCal URL that Elvestay provides and paste it into each external portal to export your Elvestay availability to them. Repeat the process for each platform and everything will be linked both ways.

Prevent overbooking: automatic blocks

Once your calendars are connected, we do the work. An automated process synchronises periodically, several times a day, checking the external calendars and applying changes without you needing to step in. When a date is booked on any channel, it is blocked on all the others, so no one can book what is already taken. Imported blocks are identified by their source, which lets Elvestay re-sync cleanly: if a booking is cancelled or changed on the source portal, the matching block is updated or removed without leaving phantom dates blocked. That way your availability always reflects reality.

Multichannel best practices

Selling across several channels pays off more when you stay consistent. Keep prices aligned across platforms so you do not compete against yourself; you can lean on our dynamic pricing engine to adjust rates to demand while keeping consistency across channels. Review the sync after major changes, such as adding a new portal, editing lots of dates or closing long seasons, and confirm everything has been reflected correctly. As for security, iCal URLs include a token that you can rotate if you suspect it has leaked, generating a new link and invalidating the old one. With these habits, managing several channels becomes simple and secure.
