Can the assistant see salaries or bank details?

No. A person comes back as name, email and status, with gender and dates on request, never custom attributes, the picture, pay or bank details. Compensation, documents and bank data are never reached.

Does it skip Personio’s own approval?

No. An absence or attendance it creates first waits for your approval in Flowplane, then goes through Personio’s usual approval for it. Editing or deleting absences and attendances, recruiting and documents are left out on purpose.

Does Codex see the password or key for Personio?

No. The key for Personio is pasted into Flowplane once and kept sealed there. Codex only gets a Flowplane sign-in for you, which you can revoke in the console.

Can Codex change things in Personio without asking?

Not by default: every change in Personio waits for your approval in the browser. Your workspace’s rules decide, per tool.

Add Personio in Flowplane
In Personio, open Marketplace, Connected integrations, Create custom integration and generate credentials, ticking only what you need (persons, absences, attendances). In the Flowplane console, add Personio and paste the client ID and secret.
Personio’s API has no personal sign-in for other apps: it works with API credentials (a client ID and secret) for the whole company. A Personio administrator creates them and ticks exactly what they may reach, and the workspace pastes them into Flowplane once. What the administrator ticked is what the assistant can do. Flowplane keeps them sealed; the assistant never sees them.

What it can do

What Codex can do in Personio

Personio is HR software for people, absences and working time. Through Flowplane an AI assistant can list the people of the company, their employments, the absence types, who is away when, and worked and break time. It can request an absence or record attendance for a person; both wait for your approval first and then go through Personio’s own approval as usual.
