What is iCal and how does it work for vacation rentals? Plain-English guide covering iCal feeds, how to find your URL on Airbnb, Booking.com and VRBO, and how to sync all your calendars.

iCal Explained Without the Technical Jargon

iCal (short for iCalendar, technically RFC 5545) is a file format for sharing calendar information. Created in 1998, it became the universal standard that virtually every digital calendar system uses — from Google Calendar and Apple Calendar to Outlook, Airbnb, Booking.com, and VRBO.

For vacation rental hosts, iCal is the answer to one of the most common problems in multi-platform hosting: how do you keep your calendars on different platforms in sync with each other?

The short answer: each platform generates a URL for your listing's calendar in iCal format. Any other calendar system that knows this URL can read your bookings and blocked dates. A sync tool like StayScan subscribes to multiple URLs simultaneously, imports all bookings into one view, and checks for conflicts.

What Data Is in an iCal Feed?

A typical vacation rental iCal feed includes: start and end dates of each reservation, guest name (on most platforms), booking status (confirmed, tentative, etc.), blocked dates (maintenance windows, manual blocks), and summary/description fields with platform-specific details.

What it does NOT include: guest contact details, payment information, messaging history, or reviews. iCal is a calendar-only format.

The Limitations of iCal Sync

  1. It is not real-time. A new booking may take 1–15 minutes to appear in the iCal feed after it is confirmed, depending on the platform.
  2. It is read-only. An iCal sync tool can read your calendar data but cannot push blocks back to the platform automatically.
  3. URLs can change. Platforms occasionally regenerate iCal URLs, particularly after account changes.

How to Find Your iCal URL on Each Platform

  • Airbnb: Calendar → Availability → scroll to bottom → Export Calendar → copy URL
  • Booking.com: Extranet → Calendar → Sync calendars → Export calendar → copy iCal URL
  • VRBO: Calendar → Import/Export → Export your calendar → copy URL
  • Agoda: Log in → Yield Management → Calendar Export → copy iCal URL

Putting iCal to Work with StayScan

  1. Collect the iCal URL from each platform where you list
  2. Open your property in StayScan and go to Calendar Sync
  3. Paste each URL using the "Add Source" button
  4. StayScan imports all bookings immediately and begins polling every 5 minutes
  5. When any two bookings overlap across any two platforms, you receive an alert

Frequently Asked Questions

Do I need to know how to code to use iCal?

No. Using iCal is as simple as copying a URL and pasting it into a sync tool.

Is the iCal URL private?

Yes — anyone with your iCal URL can read your booking calendar. Treat it like a password. If it is compromised, you can generate a new one from your platform settings.

Can I use iCal to sync a direct booking website?

Yes. Most direct booking platforms generate iCal URLs. Connect them to StayScan alongside your OTA feeds for complete calendar visibility.
