# Full Sync

What Full Sync does, when to run it, and when it won't help.

Whenever you change a price, close a date, or a booking comes in, Hostel Mate sends that update to every connected channel straight away. Most of the time that's all you'll ever need. This page is for the times it isn't.

## What Full Sync does

Full Sync re-sends everything for the next 12 months to a channel: availability, prices, minimum stay, closed dates. Not just what changed recently, all of it. It's the quickest way to get a channel back in line when it's showing something different from what you see in Hostel Mate.

Where you find it depends on how the channel is connected:

| Channel                                                             | Where to run it                                                                     |
| ------------------------------------------------------------------- | ----------------------------------------------------------------------------------- |
| Hostelworld, Coworksurf, Mixdorm (our direct connections)           | Channel Manager → **Manage Connection** → **Sync Property**                         |
| Booking.com, Expedia, Airbnb, Agoda, MakeMyTrip and everything else | Channel Manager → **Open Manager** → open the channel → **Actions** → **Full Sync** |

It runs in the background. Give it 10 to 15 minutes, then check the channel's **extranet calendar**. Don't judge it by the public booking page: those pages cache prices, and the platform often adds its own discounts or markups on top of what you send.

## When to run it

* The channel shows different prices or availability from Hostel Mate
* You just connected the channel and want to be sure everything went across
* You added or removed rooms or beds
* The channel had an outage on their side

## When it won't help

* **The date is closed by a minimum-stay rule.** The channel may still display a price for that night, but nobody can book it, so the number shown doesn't matter. What matters is the price on the nights that *are* bookable.
* **The room mapping is wrong.** Full Sync sends the right numbers to the wrong room. Fix the mapping first, then run it.
* **The platform is running its own promotion.** A 10% mobile discount on Booking.com is theirs, not ours. Check the extranet, not the public price. See [What Hostel Mate Controls](/channel-mapping-guides/what-hostel-mate-controls.md).

## Missing bookings is a different problem

Full Sync sends prices and availability *out* to the platform. It doesn't pull bookings *in*. If reservations you can see in the platform's extranet aren't in Hostel Mate, see [Pull Future Reservations](/channel-mapping-guides/pull-future-reservations.md) (or, for Hostelworld, [Import Bookings](/channel-mapping-guides/import-bookings.md)).

## Still not matching?

Write to us in the chat with:

* Which channel, and roughly when you connected it
* A link to your listing on that platform
* A screenshot of the extranet calendar showing the wrong price or availability, with the dates visible
* The room and dates you expected, and what Hostel Mate shows for them

With that we can usually tell you within a few minutes whether the update left our side, whether the platform confirmed it, and what to change.
