Connect Dayforce to Hypamoon
Yes. Dayforce 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 Dayforce, answered from its own docs.
- Public API docs

- A key you create yourself
- Yes. Calls use a Dayforce user account whose role has the Web Services feature, which your own Dayforce admin manages. help.dayforce.com
- Versions or a changelog

- How it signs in
- Basic authentication with web services credentials, or an access token from the Dayforce identity service sent as a Bearer token.

- Not confirmed.
- Hosting
- Cloud
What you can build
Pull employees, schedules and time off from Dayforce into your own screen and send punches or hours from your own tools.
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.
- Formerly Ceridian Dayforce.

Fill in what to read and write, and send it.

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.
