Connect Claude & ChatGPT to HR-ON

Ask your AI who is absent next week, which documents an employee still has to sign, or to create a new employee in HR-ON. It can read and update employees, departments, absence, documents and competences, and invite new people to HR-ON. Staff questions get answered without looking through each profile.

“Who is absent next week?”
The AI lists absences for all employees between the dates you give.
“Create Sofie Jensen, [email protected], in the Sales department and send her an invitation.”
It finds the department and creates the employee with name, email and department, and HR-ON emails her an invitation.
“Which documents is Lars still to sign?”
It finds Lars and lists the documents sent to him that are still waiting for signature.

Questions

What can the AI do in HR-ON?

The AI can read the company, employees, employee count, departments, absences, documents, unsigned documents, competences, roles, system fields and custom fields. It can create and update employees and departments, archive an employee, add competences to an employee and send a new employee an invitation to HR-ON.

Does the AI see my HR-ON credentials?

No. Your HR-ON credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Creating employees, sending invitations and archiving employees can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HR-ON connects with OAuth, and this OAuth connection needs the HeyMyApps Pro plan. HeyMyApps also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own HR-ON account.

How do I get HR-ON API credentials?

HR-ON's Staff API uses a client ID and client secret for your HR-ON account. If you do not have them, ask HR-ON support at [email protected] for API credentials. Then paste both into HeyMyApps.
