What your team gets
One API for every channel
Push availability, rates and restrictions once. We send them on to each channel at the pace that channel allows.
Bookings back by webhook
New, changed and cancelled OTA bookings reach your server as signed webhooks.
Room types and rate plans by API
Create a hotel's room types and rate plans from your PMS. We set them up on the channel manager for you.
A sandbox of your own
Test every call on a sandbox hotel that no channel ever sees, with test bookings that fire the real webhooks.
One key for all your hotels
A company key works for every hotel that has allowed your access. Each hotel stays in control of it.
One invoice a month, if you want it
We can bill you instead of your hotels: one invoice a month for all of them. Or each hotel pays us directly.
Your first call, and our answer
Send a date range and a room count. We answer at once and pass the change on to every connected channel.
- Writes are answered at once and sent on in the background, so a slow channel never holds up your PMS.
- We keep to each channel's limits for you, and a change waits until it lands. It is never dropped.
- Every call, answer and error is in the docs, with a Postman collection to try them.

Common questions
Can't find yours? WhatsApp us. A person who has worked a front desk replies.
Ask us directly →Do my hotels need to use your PMS?
No. Your hotels keep your PMS. They use only our channel manager, and your PMS talks to it through the API.
Which channels can my hotels connect?
Booking.com, Airbnb, Expedia, Agoda, MakeMyTrip and 170+ others, all through our channel manager.
How do bookings reach my PMS?
Each new, changed or cancelled OTA booking is sent to your server as a signed webhook. You can also fetch them from the API.
What does it cost?
The sandbox is free. For live hotels it depends on how many you connect and who pays: you, with one invoice a month, or each hotel. We agree the price on a call.
Who connects each hotel to its channels?
You or the hotel owner, from our channel manager screens. Our team helps with the first ones.
