PostNL & DHL API Integration | Shipping Automation
Connect PostNL and DHL shipping APIs for label creation, pickups and tracking inside your WMS or storefront.
What is PostNL and DHL?
PostNL and DHL expose business APIs for labels, rating and tracking. Both require commercial contracts and sandbox credentials.
Why integrate?
Manual label workflows do not scale. Automation reduces address mistakes and speeds fulfillment.
Common use cases
- Batch labels after warehouse picking waves
- Choose carriers dynamically based on destination cut-offs
- Generate return labels from a customer portal
- Push tracking milestones into notification services
Technical approach
We introduce a carrier abstraction so you can add providers later. Each carrier gets auth, payload mapping and error translation.
Investment and timeline
Dual-carrier projects double certification effort; we recommend phased go-lives.
