All you need to know about calendar synchronization

Updated on 03/25/2026

Do you list your accommodation on multiple platforms and worry about double bookings? Good news: Roomlala allows you to synchronize your calendar with your other platforms (Airbnb, Booking, Google Calendar, etc.) using the iCalendar (iCal) format. Here's how it works.

Accessing Calendar Synchronization

Log in to your Roomlala account, then go to your listing page. Click on the Calendar tab, click on the calendar you want to synchronize, then scroll down to the "Synchronization: calendar import / export" section.

Importing an External Calendar into Roomlala

Importing allows you to automatically retrieve unavailability dates from another calendar (for example, your Airbnb or Booking calendar) to block them in your Roomlala calendar. This way, you avoid duplicate bookings.

How to do it?

  • In the calendar synchronization section, click on "Import a calendar".
  • A window opens. Enter the calendar name (for example, "Airbnb" or "Booking") in the "Calendar name" field.
  • Paste the iCal address of your external calendar into the "Calendar address (url)" field. This address starts with http:// or https:// and is usually found in the synchronization settings of the other platform.
  • Click on "Import calendar".

Roomlala then automatically retrieves the dates blocked on the other platform and marks them as unavailable on your listing. The synchronization updates regularly to reflect the latest changes.

Where to find the iCal address for my other platforms?

  • On Airbnb: go to your listing's availability settings, "Calendar synchronization" section, then copy the export link.
  • On Booking.com: in the extranet, go to "Rates & Availability" then "Calendar synchronization" and copy the iCal link.
  • On Google Calendar: open your calendar settings, then copy the address in iCal format from the "Secret address in iCal format" section.

What happens in case of an error?

If synchronization encounters a problem (inaccessible address, unrecognized format…), an "Error" badge will appear next to the imported calendar. Check that the address is still valid and accessible. If the problem persists after several attempts, synchronization will be automatically disabled. You can then delete it and create a new one with a corrected address.

Exporting Your Roomlala Calendar to Another Platform

Exporting works the other way around: it allows your other platforms to retrieve the unavailability dates from your Roomlala listing.

  • In the synchronization section, find the line "Export link for your Roomlala calendar".
  • Click "Copy" to copy the link to your clipboard.
  • Paste this link into the synchronization settings of your other platform (Airbnb, Booking, etc.), in the area provided for importing an external calendar.

The other platform will regularly consult this link to update its availabilities based on your Roomlala calendar.

Two-Way Synchronization

For complete synchronization between Roomlala and another platform, both operations must be performed:

  • Import the calendar from the other platform into Roomlala (to block dates booked elsewhere).
  • Export your Roomlala calendar to the other platform (to block dates booked on Roomlala).

This way, your availabilities remain consistent everywhere, regardless of the platform on which a booking is made.

Deleting an Imported Calendar

If you no longer wish to synchronize an external calendar, click the delete icon (trash can) next to the relevant calendar in the import list. The unavailability dates from that calendar will be automatically removed from your listing. Your manually blocked dates and your Roomlala bookings will not be affected.

Good to Know

  • Roomlala is compatible with iCalendar (iCal) format calendars, used by most rental platforms and calendar applications.
  • You can import multiple external calendars for the same listing.
  • Synchronization takes into account events up to one year in the future.
  • If you do not update your calendar for a long period, Roomlala will send you an email reminder to invite you to check your availabilities.
  • Dates manually blocked on your Roomlala calendar are never modified by synchronization.
