How to combine multiple iCal feeds into one URL

The fastest way to simplify calendar imports is to stop managing five separate sync paths. A single combined iCal URL gives every import target the same blocked dates from Airbnb, VRBO, Booking.com, Google Calendar, and other compatible sources.

Why combine feeds at all?

  • Fewer calendar import paths to manage
  • One URL to reuse across platforms where iCal import is supported
  • Less confusion when troubleshooting stale imports
  • A cleaner handoff into Google Calendar or OTA import settings

How to merge your feeds

  1. 1

    Collect every export URL first

    Copy the iCal export URLs from Airbnb, VRBO, Booking.com, Google Calendar, or any other source you want included.

  2. 2

    Paste them into iCalendar Sync

    Open the tool, paste each source URL, and generate one permanent combined URL.

  3. 3

    Replace separate imports with the combined URL

    In every destination that supports iCal import, replace the old single-source imports with the new combined URL so each destination sees the same availability state.

The combined feed is still iCal

This does not create instant real-time sync. Platforms still fetch on their own schedules. What it does do is make sure every fetch pulls from one complete availability source.

When to move beyond the free tool

The free tool is ideal when you simply need one combined URL. If you also want a website availability calendar, manual date blocking, export access tracking, or a direct booking path, that is where RentalBeam becomes the better fit.

RentalBeam adds a Calendar Sync view, export URL tracking, combined exports, and an embeddable website availability calendar for hosts who want more visibility and control.

Combined-feed questions

The free tool supports up to 3 sources per combined URL. If you need more source aggregation, manual date controls, or export controls, RentalBeam is the upgrade path.

Yes. Any valid iCal/ICS source can be merged into the same combined URL.

No. Once generated, the URL remains permanent so you can keep using it in import settings.
