DHL Integration & Shipping Software Development

Custom DHL API integration using C# and .NET for shipment creation, DHL service selection, shipping rates, labels, tracking and integration with existing business systems. The integration can connect DHL shipping capabilities with existing ERP, order management and logistics applications, allowing shipment information to be prepared within the business application and processed through the DHL carrier API. The application can prepare sender, receiver and package information, determine the appropriate DHL shipping service, construct the carrier-specific shipment request and process the response returned by DHL. DHL shipment processing can also be incorporated into a broader multi-carrier shipping platform where carrier-specific API communication remains separated from the common business shipping workflow.

DHL Integration & Shipping Software Development

Horizon Softwares develops custom DHL shipping integrations for .NET applications that need reliable shipment processing, DHL service selection, rates, labels and tracking. The integration can be built into existing ERP, order management and business systems or used as part of a larger multi-carrier shipping platform.

1. Prepare Shipment — Prepare sender, receiver, reference and package information, including multi-package dimensions, quantities and weights.

2. Resolve DHL Service & Contract — Retrieve the configured DHL delivery service and contract information, then determine the appropriate DHL integration and authentication path.

3. Build DHL Shipment — Construct the DHL shipment with sender, receiver, service, billing, reference and package information, including required country and measurement formats.

4. Process Customs Information — For non-EU shipments, build customs data including export purpose, product details, HS codes, origin, values and weights.

5. Submit Shipment to DHL — Serialize the carrier-specific shipment structure and submit it through the appropriate DHL API integration using the configured authentication.

6. Process DHL Response — Record the DHL API transaction, process the returned response and determine whether the shipment was successfully created.

7. Process Labels & Tracking — Extract DHL tracking numbers and label data, store the generated labels and associate them with the shipment.

8. Process Documents & Errors — Process export documents, preserve carrier responses, capture API errors and update shipment status.

DHL INTEGRATION CAPABILITIES

DHL API Integration: Real-World Implementation

MODULE

DHL Shipping Integration Workflow

The DHL integration is implemented as a carrier-specific workflow within a C# / .NET shipping application. Shipment information is prepared within the application before the required DHL service and shipment information is constructed.

The application separates the common shipping workflow from the carrier-specific DHL implementation. This allows DHL communication and response processing to remain within the carrier integration layer while the surrounding business application continues to use its common shipment workflow.

Implementation flow:

Prepare shipment information → determine DHL service → build packages → build DHL shipment → submit to DHL → process labels and tracking → handle carrier response.

MODULE

DHL API Integration — REST & SOAP

The DHL integration supports two carrier communication paths within the C# / .NET shipping application. The standard DHL integration communicates through the DHL REST API, while shipments using the separate Other Contract integration are processed through a SOAP-based DHL service.

Both integration paths use the application's common shipment information and then construct the carrier-specific request required by the selected DHL service. This keeps the surrounding business application independent of the underlying DHL communication protocol.

REST integration: Prepare shipment data → construct DHL request → authenticate → submit through DHL REST API → process carrier response.

SOAP integration: Prepare shipment data → construct DHL contract request → build SOAP envelope → apply SOAP authentication → submit request → process XML response.

The resulting carrier information can then be converted into the application's standard shipment result so that tracking, labels, status handling and business workflows remain consistent across both integration paths.

DHL Shipment Creation & Package Processing

Shipment creation starts with information supplied by the existing business application. Sender, receiver and package information are prepared before the DHL-specific shipment request is constructed.

Package information can be prepared using the application's common shipment representation before being converted into the carrier-specific structure required by DHL.

This approach allows the surrounding shipping application to maintain a common shipment workflow while the DHL integration layer handles carrier-specific request construction.

Shipment construction:

Prepare order data → prepare sender and receiver information → build packages → construct DHL shipment → submit shipment.

MODULE

DHL Services & Shipping Rates

The DHL quoting and service-selection workflow can use the shipment information supplied by the business application to determine applicable DHL services.

Shipment details such as sender and receiver information, package dimensions, weight and quantity can be used as inputs to the service and rate-processing workflow.

The resulting DHL service and rate information can then be returned to the calling application so that the appropriate shipping option can be selected before shipment creation.

Quote workflow:

Prepare shipment information → determine applicable DHL services → process DHL rates → return available services and rates.

MODULE

DHL Shipping Labels

DHL shipment creation can return shipping label information as part of the carrier response. The integration processes the returned label information and associates it with the corresponding shipment.

Keeping label processing inside the carrier integration allows the surrounding business application to continue working with a consistent shipment workflow without having to understand DHL-specific response structures.

Label workflow:

Create shipment → receive DHL response → process label information → associate label with shipment.

MODULE

DHL Tracking & Carrier Response Handling

After successful shipment creation, the DHL response can be processed to obtain tracking information and other shipment results returned by the carrier.

The tracking information is associated with the corresponding shipment so that the existing business application can continue managing the shipment after the carrier request has completed.

Unsuccessful DHL responses can also be processed by capturing the carrier error, updating the shipment processing status and returning the carrier result to the calling application.

Response workflow:

DHL response → determine success → process tracking and labels → persist shipment information. If unsuccessful → capture carrier error → update shipment status → return carrier result.
