Delivery endpoints were replaced by /v2/transports endpoints!
Documentation may be found here.
All transport endpoints must be called via MPAPI /v2/transports endpoint with your client_id as a query parameter.
i.e., /warehouses/{warehouse-id} should be called as /v2/transports/warehouses/{warehouse-id}?client_id=myClientId
Deliveries are designed to manage general deliveries used within Mall Group and deliveries provided by partner. There is a rule for setting particular delivery method attributes - as for dimensions (width, length, height and width) if minimal dimension value is set, then the maximal value of the relevant dimension becomes required. It is possible to set only one of the dimensions, however it is recommended to set all dimensions.
