Connect Microsoft Bookings to Hypamoon
Yes, with one catch. Microsoft Bookings has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.
OpenThe check
Three questions about the API of Microsoft Bookings, answered from its own docs.
- Public API docs
- Yes. Read the docs
- A key you create yourself
- Yes. Register an app in your own Microsoft Entra tenant; the Bookings endpoints accept both delegated and application permissions. learn.microsoft.com
- Versions or a changelog
- Yes. Part of Microsoft Graph v1.0. learn.microsoft.com
- How it signs in
- Microsoft Entra ID OAuth; application permissions with the client credentials grant for server jobs, or delegated permissions for a signed in user.
- Webhooks
- Not confirmed.
- Hosting
- Cloud
- Condition
- The business needs a Microsoft 365 subscription that includes Bookings; the docs name Business Premium.
What you can build
Show free staff times and book or cancel an appointment from a chat or phone line, and list today's appointments.
Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work
Good to know
- Microsoft Bookings signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Microsoft Bookings takes more work: ask your chat to check this first.
- Personal Microsoft accounts are not supported. An admin must consent to the Bookings permissions.

Tool not listed? Ask the chat to check its API.
The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
Fill in the name of your software. Checking needs no connection to Hypamoon.
