Connect Factorial to Hypamoon
Yes. Factorial has a public, versioned API and you create the key yourself, so your chat can write the adapter.
OpenThe check
Three questions about the API of Factorial, answered from its own docs.
- Public API docs
- Yes. Read the docs
- A key you create yourself
- Yes. An admin generates an API key in the company settings, without registration or approval. apidoc.factorialhr.com
- Versions or a changelog
- Yes. Dated versions in the path, each supported for one year. apidoc.factorialhr.com
- How it signs in
- API key in the x-api-key header that does not expire; OAuth 2.0 for marketplace and partner apps.
- Webhooks
- Yes. It can tell your app when something changes. apidoc.factorialhr.com
- Hosting
- Cloud
What you can build
Look up employees, absences and shifts from your chat, and create time off requests or new employees for approval.
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
- Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
- An API key sees all company data; use OAuth scopes if you need narrower access. An expired API version does not fail loudly, so pin and update the version on purpose.

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.
