Soft-deleted units are never returned. Rows are ordered by `name`, then by `id`, so paging can neither repeat nor skip a unit. Requires `packaging:read` (a `packaging:write` key satisfies it); customer workspace with the PPWR module enabled. ## OpenAPI ````yaml GET /api/ppwr/units openapi: 3.1.0 info: title: Polygon One Compliance API description: >- API for integrating ERP systems with the Polygon One EUDR Compliance Platform.
