Deprecation of 'vacation_day_balance' attribute in the GET Employees endpoint deprecation

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.
