Syncing your calendar across multiple platforms is essential for managing your property efficiently and avoiding double bookings. This guide walks you through connecting your Holidu calendar with other vacation rental platforms and booking channels using iCal synchronization.

Supported Calendar Channels

Holidu supports two-way iCal synchronization with the following platforms:

• Admin
• Abritel
• Airbnb
• Atraveo
• Avaibook
• Avantio
• Booking.com

• Feratel
• Fewomanager.de

If your calendar provider is not listed, contact them to confirm they support two-way iCal synchronization. Always test the connection manually by creating a test block on each calendar to verify the sync works correctly.

Please note: We cannot guarantee compatibility with every external iCal calendar. Always verify that your specific sync configuration works as expected before relying on it for availability management.

Important Notes for Popular Booking Platforms

Booking.com

When configuring Booking.com synchronization, ensure that in the export settings on Booking.com, you tick the box for Booked and Closed Dates. This ensures both your confirmed bookings and manual blocks synchronize correctly with Holidu. For detailed instructions, refer to Booking.com's official iCal connection guide.

Airbnb

Airbnb's iCal synchronization has a specific limitation: it only supports calendar dates from today through the next 364 days. Any availability changes beyond this 364-day window will not be synced to Holidu. Plan your availability management accordingly. For more information, see Airbnb's iCal help article.

VRBO

Troubleshooting Tips

The Sync Is Not Working

Check that your iCal URL is copied correctly without any typos or extra spaces. Even small errors in the URL can prevent synchronization from functioning. Copy the URL directly from your external provider without manual editing.

Updates Are Not Appearing in Real Time

Calendar synchronization may not update immediately. If your blocks or bookings are not appearing right away, click the green Refresh button next to your synchronization to manually trigger an update. Changes typically appear within a few minutes after refreshing.

Verify Your Sync with a Manual Test

After setting up synchronization, always test the connection by creating a test availability block in one calendar and checking if it appears in the other calendar within a few minutes. This manual test confirms your sync is working correctly before you rely on it for actual bookings.

Recurring Sync Issues

If your sync repeatedly fails, verify that both your Holidu account and external platform account have the correct access permissions. Some platforms require you to explicitly grant calendar access. Check your external provider's settings to ensure Holidu has permission to read and write to your calendar.
