Three steps to unified calendar sync
Add your Airbnb, VRBO, or Booking.com iCal export URLs (up to 3).
One click. Your feeds are merged into one permanent export URL.
Paste the one URL into every platform. All calendars stay in sync.
And how a combined iCal feed helps prevent them
Airbnb, VRBO, and Booking.com each sync calendar data on their own schedule - sometimes waiting hours between updates. During that gap, a date booked on one platform still appears available on others.
By combining all your platform calendars into one feed and importing that single URL back into each platform, every platform sees the blocked dates from every other platform. This drastically reduces the sync window and the chance of overlapping reservations.
This tool generates your combined feed URL for free. For additional control - custom date blocking, visual calendars for your website, and a direct booking form - explore RentalBeam.
Step-by-step for each major platform
It combines multiple iCal/ICS calendar feeds into one URL. Paste your Airbnb, VRBO, and Booking.com calendar export URLs, and you get a single combined URL you can import anywhere. All blocked dates from every platform appear in one feed.
Yes, completely free with no account required. Paste your URLs, click generate, and use the combined URL immediately. For advanced features like custom colors, date blocking, and a booking form widget, you can create a free RentalBeam account.
No. Your combined URL is permanent and updates automatically whenever your booking platforms update their calendars. You can safely paste it into Airbnb, Google Calendar, or any other tool that accepts iCal imports.
In Airbnb, go to your listing, open the Availability tab, scroll to "Connect calendars", and click "Export Calendar". Copy the URL that starts with https://. The same process works for VRBO (under Calendar Settings) and Booking.com (under Calendar & Pricing > Sync calendars).
Double bookings occur when booking platforms fail to sync calendars quickly enough. Airbnb, VRBO, and Booking.com use iCal feeds as the sync mechanism, but each platform fetches updates on its own schedule - sometimes hours apart. During that gap, a date that was just booked on one platform still appears available on others.
Yes. Use the "Import calendar" feature on each platform and paste your combined URL. This way each platform sees the blocked dates from all your other platforms, reducing the risk of double bookings.
Up to 10 iCal sources per combined feed. This covers multi-platform hosts listing on Airbnb, VRBO, Booking.com, Google Calendar, and other iCal-compatible platforms.
No. iCal feeds only contain blocked date ranges. No guest names, emails, phone numbers, or contact information is included. Your combined feed shows the same date-level information as the original platform exports.
