Visma External Periods API
Operations for reporting per-employee values for a deviation period from an external system. An external period carries a percentage-based project/cost-center distribution for the employee's worked time. The values are picked up when they are imported into the payslip for that period. A period cannot be updated — delete it and create a new one instead. An integration can only see and manage the periods it has created itself.
