  title: Personio Public API v2 Absence Periods Projects API
  description: 'Next-generation Personio Public API for HR management data including

    persons, absence periods, projects, and webhooks. Authenticates via OAuth

    2.0 Client Credentials Grant: exchange a Client ID and Secret at

    POST /v2/auth/token for a short-lived Bearer access token, then include

    it in the Authorization header of subsequent calls.


    Only a representative subset of the public v2 surface (persons, absence

    periods, projects, webhooks) is modeled here. See the API reference

    linked under externalDocs for the full catalog.
