As of April 8, 2024 the attribute ‘vacation_day_balance’ will be deprecated and removed from the GET Employees endpoint’s response, in favour of retrieving absence data from https://developer.personio.de/reference/get_company-employees-employee-id-absences-balance; This adjustment is aims to enhance usability and accuracy of the retrieved absence data as the original endpoint defaulted to returning only the balance of the highest-order absence type. The alternate endpoint (mentioned above) now offers balances for all absence types where the employee possesses a balance. We strongly advise customers and partners integrating this feature to make use of the dedicated endpoint mentioned above to prevent any integration disruptions.

The POST Absence Periods endpoint has been upgraded in a graceful manner, to accept hourly absence requests in accordance with the absence certificate requirement set on the Personio application. It is now optional to upload a certificate when creating an absence via the UI for hourly absence types, mirroring the behaviour of daily absence types. So creating an absence through the endpoint wouldn’t require uploading a certificate. However, the capability to upload a certificate itself through the endpoint remains unsupported at this time.

As of 8 January 2024, there will be a new field added to the response of the GET Employees endpoint i.e. 'preferred_name'. Please note that this is an additive change and will not break existing integrations.

The maximum number of employees whose attendances can be posted in a single POST request to this Attendances endpoint (https://developer.personio.de/reference/post_company-attendances) is set to 100, in order to maintain system stability.

As of August 25, 2023 the Hourly Absences endpoint i.e. /company/absence-periods, has had an update to the pagination logic of responses, to match the existing API documentation i.e. the 'offset' variable has been updated to refer to a page-level offset rather a per-record-level offset, as was previously the case.

Starting November 16, 2023, in order to improve the performance of the GET Employees endpoint and ensure system stability, we are introducing pagination as a mandatory feature when the updated_since filter is used to retrieve the data.

Pagination can be used in the GetReport Endpoint via page and limit query parameters. The limit indicates how many employees per page should be returned. Example: /company/custom-reports/reports/{report_id}?page=2&limit=100
