Synchronising the Airbnb and Booking.com calendars, step by step (without falling into the trap)

What you need before you start

Three things are enough: your Airbnb login, your login to the Booking.com extranet (the partner area), and twenty quiet minutes, preferably on a computer. The connection is free and consists of copying and pasting two links. No technical skill is needed.

One idea to hold on to before touching any menu: a calendar link is a subscription, not a one-off delivery. When Booking.com receives the link to your Airbnb calendar, it comes back to read it regularly and updates its availability. But that subscription only works in one direction. For both platforms to keep each other informed, you need two connections, one each way. If the idea of a subscription is new to you, take five minutes to read our page on the iCal link explained simply, then come back: the rest will be plain sailing.

One last preparation: open both calendars side by side and compare them with your own eyes. If a date is already booked on one side and free on the other, make a note of it. Connecting them will pass the held dates along, but it is worth knowing beforehand what it is going to find. And if you discover two bookings on the same dates right now, deal with that emergency first: what to do is in what to do about a double booking.

One question comes up again and again: in what order should the two connections be made? The honest answer: technically the order does not matter, the two directions are independent. The right reflex lies elsewhere: start by protecting the platform that brings you the most bookings. If most of your sales come through Airbnb, have Booking.com read the Airbnb calendar first, so that Booking.com stops selling dates already taken as soon as possible. Then move straight on to the second direction, the same day: a connection half made is the most common trap in this kind of guide.

The menu paths described below are the ones observed in August 2026. Labels shift from one season to the next; the words to look for stay the same: calendar, sync, import, export.

The whole connection, step by step

1. Copy the calendar link of your Airbnb listing

Log in to Airbnb, open your listings and choose the property concerned. Open its calendar, then its settings. Under the section about availability, look for "Connect calendars", then "Export calendar". Airbnb displays an internet address containing the word "ical". Copy the whole of it, cutting nothing at either end. While you are there, paste it into a note, labelled "Airbnb link": you will need it again.

2. Paste that link into Booking.com

Log in to the Booking.com extranet and open your property. In the tab about the calendar and rates, look for "Sync calendars", then the button offering to add or import a calendar. Paste the Airbnb link into the field provided, give it a clear name ("Airbnb" will do) and confirm.

If Booking.com refuses the link with a message such as "invalid link", two causes dominate: an incomplete link (copy it again), or a link that is not a calendar link (you have copied the address of your listing page). The full diagnosis is in our guide on the invalid .ICS link error.

At this point half the work is done: Booking.com knows about the Airbnb bookings. The reverse is not true yet. Whatever you do, do not stop here.

3. Copy the calendar link of your Booking.com listing

Still under "Sync calendars" in the extranet, look this time for the export button: Booking.com gives you the calendar link for your property. Copy the whole of it and file it in your note, labelled "Booking.com link".

If the link shown begins with webcal:// rather than https://, that is not a mistake: simply replace webcal:// with https:// before pasting it elsewhere. It is the same link, written differently.

4. Paste that link into Airbnb

Go back to Airbnb, to "Connect calendars", and this time choose "Import calendar". Paste the Booking.com link, name it clearly ("Booking.com"), and confirm. Airbnb makes a first reading straight away and shows the dates held from Booking.com, usually within minutes.

5. Check the connection, stopwatch in hand

Do not close everything down telling yourself it looks about right. Run the test in both directions: hold a date far in the future on Airbnb, note the time, and watch for it appearing on Booking.com. Then do the reverse. Allow one full reading cycle, that is 2 to 3 hours each way: Airbnb publishes a rhythm of 3 hours, while Booking.com's is reported by hosts, as recorded in August 2026; the detailed figures platform by platform are in our table of iCal synchronisation times. The full method for this test, including the check from a guest's point of view, is described in how to check that your calendars are really synchronised. Remember to release your test dates at the end.

Check as well that bookings already in place before the connection do appear on the other side. That is the first service synchronisation renders you.

The traps at the moment of connecting

Stopping after one direction. This is the most frequent and the most expensive trap. A guide followed halfway gives a false sense of safety: bookings travel one way, and the first booking taken on the other side holds nothing opposite. Count your connections: you need two per pair of platforms.

Copying the link of the wrong listing. With several properties, pasting the link of property A into the listing for property B holds phantom dates on both sides. Hence the value of clear labels in your note.

Pasting the address of the listing instead of the calendar link. The page with the photographs and the Book button is not a calendar. The platform will refuse it, usually with a message about the ".ICS" format.

Expecting a perfect mirror. Synchronisation carries the dates that are taken, and nothing else. Not the rates, not the minimum stay, not the guests' names. If the two calendars do not show the same details, that is normal: only the held dates need to match.

Carrying on copying dates by hand. To be on the safe side, some owners keep the habit of holding dates manually, on top of the synchronisation, for dates booked elsewhere. The intention is good, the result is treacherous: when the original booking is cancelled, synchronisation frees the dates, but your manual hold stays put. Weeks later, you will wonder who closed those dates and why. Choose one system and one only: synchronisation, backed by a regular check.

The trap nobody mentions: a successful set-up is not a reliable one

Every guide stops at the moment the test date appears on the other side. Champagne, it is connected. What they do not say: you have just checked that synchronisation was working that day. Nothing more.

Two threats remain in place, and they account for almost every double booking suffered by owners who are nonetheless properly connected.

The window between two readings. Booking.com does not read your Airbnb calendar continuously, it reads it again every 2 to 3 hours or so. Between two passes, it sells on the basis of information that is out of date. Two guests can therefore book the same dates an hour apart, each on a platform, while everything is working normally. No setting removes that window, and nobody can promise otherwise.

The silent outage. A calendar link can die without a sound: the platform changes it after a change to your account, a setting drops out, an import switches itself off. When that happens, the platform that was reading the link does not warn you. It keeps the last version it received and displays it as if nothing were wrong. A set-up that has been broken for three weeks looks exactly like one that is working. The outage only becomes visible with the booking too many.

In other words, the connection you have just made is necessary, but it is not enough on its own. It will have to be checked from time to time, or watched continuously.

Staying calm once you are connected

The minimum: run the test-date check again after every change of setting, before every high season, and on your return from any time away. Between two checks, the blind spot remains: checking once a week leaves on average 3 to 4 days between an outage and its discovery.

That is exactly the gap that continuous watching fills. A service that reads each of your calendar links every 30 minutes (every 15 minutes on the Pro plan), compares what they contain, and alerts you by email as soon as a link stops answering or two bookings overlap. A health screen also shows when each platform last read your calendar: the question "has Booking.com seen my latest booking?" has an answer in plain sight, rather than being a gamble. It does not shorten Airbnb's or Booking.com's reading cycles, and nobody can. What it changes is the part that depends on you: the time between the problem and the moment you learn of it. A double booking reported the same day is untangled with one telephone call; discovered the day before arrival, it becomes the worst day of your season. The other defences, buffer days or approving each booking by hand, are compared in how to avoid double bookings.
