How do I integrate Personio API with my application?

Apideck provides a unified HRIS API that makes Personio integration simple. Sign up for free, enable Personio in your dashboard, and use our Vault component to let your users connect their Personio accounts. We handle OAuth authentication, token refresh, and data normalization automatically.

What Personio data can I access through Apideck?

Our Personio integration supports 2+ data models including employees, and time offs. You can perform read and write operations through our unified API, working with the same code structure across all hris platforms.

How does Personio authentication work with Apideck?

Apideck's Vault handles Personio authentication completely. Your users connect their Personio accounts through our secure, white-label UI. We manage OAuth tokens, automatic refresh, and credential storage, so you never have to implement Personio's auth flow yourself.

Does Apideck support Personio webhooks?

Yes, Apideck provides real-time notifications when Personio data changes. Our unified webhook system normalizes events across all integrations, so you handle Personio events with the same code you use for other hris platforms.

Why use Apideck instead of Personio's direct API?

Using Apideck's unified API instead of Personio's direct API saves significant development time. You get normalized data models, automatic auth handling, and the same integration code works with 200+ other apps. When Personio updates their API, we handle the changes so your integration keeps working.

How quickly can I build a Personio integration?
