DHL Freight API Farm (REST, Sweden)

API Farm is DHL Freight's REST hub for the Sweden market — domestic Swedish road freight plus Sweden-originating international transports. It is a wholly separate surface from MyDHL Express, DHL eCommerce Americas, and DHL Post & Parcel Germany: a different developer portal at dhlpaket.se/dashboard/services/api-farm, different base URLs (api.freight-logistics.dhl.com for production, test-api.freight-logistics.dhl.com for sandbox), and a different authentication model. The DHL Group Developer Portal at developer.dhl.com explicitly redirects Sweden traffic here for domestic and Sweden-originating international transports. Authentication uses a per-application GUID API key (the client-key). After signing up, you create an Organisation, register an Application, and DHL shows the client-key exactly once — save it securely because it cannot be retrieved later. The key must be sent in the request header on every call. Production keys require a separate registration at admin.freight-logistics.dhl.com plus an Implementation Request; DHL Freight will not activate production access until at least one validated test request per API is recorded. The surface is broad. TransportInstruction creates road-freight orders, PickupRequest books pickups, and Print returns labels, return labels, CMRs, and other documents as Base64-encoded PDFs. PriceQuote returns prices and supports contract pricing when combined with e-ID account-number validation. Product, AdditionalService, PostalCodes, Terminal, and TimeTable describe what is sellable, allowed, and routable on a given lane, while ServicePointLocator and HomeDeliveryLocator power last-mile UX. Tracking is intentionally out of scope here: DHL delegates tracking to the global Shipment Tracking - Unified API at developer.dhl.com. Cancellations are not API-accessible — you cancel in your own system and phone DHL Customer Service at 0771-345 345. For more than 10,000 shipments per day DHL recommends traditional EDI rather than API Farm.
