We are currently trying to implement the DHL Parcel EU API in our app. Everything seems work, but there is one problem; We need a shipment label ID to generate a shipping label via the POST /shipments endpoint. However, there seems to be no clear way to retrieve this ID after creating a shipment.
Is there a specific API endpoint we should use to obtain the shipment label ID?
Or should we extract this from the response of the shipment creation request?
Does anyone know a solution to this?
