Personio
Add Personio to your product for your customers, and give your AI agents governed access to it.
Embed a Personio integration so your customers can work their own HR records from inside your product instead of rekeying them. Personio holds employees and their employment detail, absence periods and absence types, attendance records and whatever custom attributes each company has added, and those attributes differ per customer so mapping is configuration rather than code. HR data access rules are stricter than most systems, so reads and writes are scoped per tenant, limited to the fields you map, and logged. fastn handles per-customer authorisation, token refresh and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own Personio account so your product reads their employees and org detail without a file export.
Create or update employee records and custom attributes from your product so a change is entered once.
Read absences and attendance per tenant so your product can plan around who is actually available.
Trigger your product when an employee is created or leaves, so provisioning and removal follow the HR event.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An HR copilot reads live employee, absence and attendance records before it answers.
An agent books or updates an absence within governed permissions, with the write logged.
An agent reacts to a new hire in Personio and starts onboarding in the customer's other connected systems.

Set up Personio in 4 steps
- 01Open the Personio connector from your fastn dashboard.
- 02Have each customer authorise their own Personio account with their API credentials.
- 03Map the employee attributes, absence types and attendance fields your product uses, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Personio integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Personio integration without building it. Your customers connect their own Personio account inside your product and work their employees, employment records and working time there, with no per-customer code on your side.
- Handle the part that actually costs time: HR data is sensitive and its access rules are stricter than most systems. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Personio update is not your on-call problem.
- One integration serves your product and your agents. The same governed Personio connection powers in-product features and gives AI agents scoped, audited access, so you keep people data current without manual re-entry without wiring it twice.

BoxPersonio integration FAQ
How do I add a Personio integration to my product?
Enable the Personio connector in your fastn dashboard, then let each customer authenticate their own Personio account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Personio client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Personio account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Personio account and only ever sees their own employees, employment records and working time. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Personio integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An HR copilot reads live employee, absence and attendance records before it answers.
Who maintains the Personio integration?
fastn does. When Personio changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
How is sensitive Personio employee data handled?
Access is scoped per tenant and limited to the fields you map, credentials are encrypted, and every read and write is logged. You expose only what your product actually needs rather than the whole employee record.
Can joiner, mover and leaver changes be automated?
Yes. Where Personio is where a hire, a role change or a departure is recorded, that change can trigger downstream provisioning or removal across the customer's other connected systems. Where Personio sits downstream of the HR system of record, the same event can be pushed into it so its worker list, schedules and access stay in step, which is where most of the manual effort sits.
What can I build with the Personio integration?
A common starting point: connect their own Personio account so your product reads their employees and org detail without a file export. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Personio integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Personio does not change your per-connector cost. You can start free with 3 connected accounts.
