Lucca HR, payroll and shifts # Connect Lucca to Hypamoon Yes. Lucca has a public, versioned API and you create the key yourself, so your chat can write the adapter. Open ## The check Three questions about the API of Lucca, answered from its own docs. **Public API docs**\ **Yes.** Public developer hub with the Lucca API reference and guides. [Read the docs](https://developers.luccasoftware.com/api-reference/latest) **A key you create yourself**\ **Yes.** With enough rights you create a client application in your Lucca account and get a client ID and secret. [developers.luccasoftware.com](https://developers.luccasoftware.com/documentation/using-api/authentication) **Versions or a changelog**\ **Yes.** Dated API versions set with the Api-Version header, a changelog and a deprecation policy. [developers.luccasoftware.com](https://developers.luccasoftware.com/changelog/overview) **How it signs in**\ OAuth 2.0 client credentials with scopes for the Lucca API; the legacy APIs take an API key in the Authorization header. **Webhooks**\ **Yes.** It can tell your app when something changes. [developers.luccasoftware.com](https://developers.luccasoftware.com/documentation/webhooks/get-started) **Hosting**\ Cloud ## Your own people overview on Lucca, for managers and the office. - Employees, job positions, employments and absences, straight from Lucca. - AI that prepares onboarding steps and spots gaps in a team's planning. - A screen for managers and a weekly email for HR. ### Ask your chat Answers straight from your Lucca data, in Claude or another chat with the full Hypamoon connection. - Who joins the company next month, and in which team? - Which teams have more than two people away next week? ### When something happens Lucca sends a webhook to your app, and the app asks AI what happens next. 1. When A new employee record is created in Lucca. AI decides AI drafts the first-week plan from the job position. Then The manager gets an email with the plan. ### A screen for your team or customers An app on your own address, with sign-in, on top of the same Lucca data. - For your team A screen for managers with their team and upcoming absences. Lucca stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Lucca waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### 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. - The legacy APIs use a fixed API key; the newer Lucca API uses client credentials with tokens. Browser calls from other domains are blocked, so calls run from a backend. ## Try it in your chat Fill in what to read and write, and send it.

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. Say this in your chat > 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.
