Connect Microsoft Planner to Hypamoon
Yes, with one catch. Microsoft Planner 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 Planner, answered from its own docs.
- Public API docs
- Yes. Read the docs
- A key you create yourself
- Yes. Register an app in Microsoft Entra ID yourself; application permissions need consent from your own tenant admin. learn.microsoft.com
- Versions or a changelog
- Yes. Stable Graph v1.0 endpoint next to beta, with a What's new page. learn.microsoft.com
- How it signs in
- OAuth 2.0 through an app registered in Microsoft Entra ID, with delegated permissions or client credentials.
- Webhooks
- Not confirmed.
- Hosting
- Cloud
What you can build
Add a task to the right plan and person from your chat, and get a Monday list of overdue tasks per team.
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 Planner 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 Planner takes more work: ask your chat to check this first.
- Part of Microsoft 365, which has its own entry; this entry is for people looking for this app on its own. Only basic plans are in the API; premium plans are not. Changes need the latest etag in an If-Match header.

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.
