A new endpoint replaces the deprecated importLeavePeriods: /figgo/api/imports/v1.0/leavePeriods. Main changes in this new endpoint are: (1) the ?type=csv query parameter is no longer required or even used and (2) it now supports an async mode through the ?async=true query parameter. By default, the process is synchronous.In case of an async import, a new endpoint enables you to track its progress: /figgo/api/imports/v1.0/leavePeriods/{summaryId:guid}/progress.
