Questions & answers
Why integrate the Deutsche Post API through Sendcloud instead of directly?
Direct Deutsche Post integration means setting up a Portokasse account, enabling the new REST API in Geschäftsanwendungen ("dp_internetmarke_rest_api_carrier_dp_sendcloud"), and managing both INTERNETMARKE (national letters and parcels) and Deutsche Post International endpoints separately.
Through Sendcloud, you authenticate once with your Sendcloud API key and use a single REST schema for Deutsche Post alongside every other carrier in your account. A direct Deutsche Post contract is required either way; Sendcloud rates aren't offered for Deutsche Post.
What happens when Deutsche Post updates or breaks their API?
Deutsche Post is rolling out the new REST API to replace older submission flows. Direct integrators have to enable the new API in Portokasse, re-test letter and parcel formats, and adjust to changes in customs and Warenpost flows.
When you ship Deutsche Post through the Sendcloud REST API, the abstraction layer absorbs those changes. Sendcloud's engineering monitors Deutsche Post's developer documentation and adjusts the carrier connector internally. Your Sendcloud request schema stays the same.
Can I use my own Deutsche Post contract?
Yes, and you have to. Deutsche Post requires a Portokasse account; Sendcloud rates aren't offered. Register at portokasse.de if you don't have one.
In Sendcloud, go to Shipping > Carriers > My Contracts, find Deutsche Post, and click Add Contract. Enter your Portokasse email, password, and EKP customer number. Then log in to Portokasse, navigate to Meine Daten > Geschäftsanwendungen, and enable "dp_internetmarke_rest_api_carrier_dp_sendcloud" so the new REST API is active for your account.
A Lite, Growth, or Premium plan is required. See the Deutsche Post contract activation Help Center article.
Which Deutsche Post products are supported through the API?
Through Sendcloud, you can ship the full domestic letter and parcel line via INTERNETMARKE plus international Deutsche Post International methods:
National letters: Standard Letter (Standardbrief) up to 20g, Compact Letter (Kompaktbrief) up to 50g, Large Letter (Großbrief) up to 500g, Maxi Letter (Maxibrief) up to 1000g
Warenpost: tracked product up to 1000g, usually next-working-dayWarensendung: small-goods compact, large, and maxi formatsInternational: Warenbrief Priority/International up to 500g, Letter Kilotarif up to 2000g
See the Deutsche Post shipping conditions Help Center article.
Which Deutsche Post-specific features does the API expose?
Deutsche Post-specific features exposed through the integration:
Letter formats with strict dimensional limits (Standardbrief, Kompaktbrief, Großbrief, Maxibrief)
Warenpostsmall-goods with shipment tracking, usually delivered within one working dayRegistered letter ("Einschreiben") on letter formats
International Warenbrief Priority and standard formats
EKP customer number routing for invoicing and contract identification
How do I track Deutsche Post parcels?
Warenpost includes shipment tracking with usually next-working-day delivery. Standard letter formats (Standardbrief, Kompaktbrief, Maxibrief) typically don't expose tracking, so tracking webhooks fire mostly for Warenpost and Warenbrief shipments.
All events normalise to Sendcloud's status taxonomy through GET https://panel.sendcloud.sc/api/v2/tracking/{tracking_number}, with the chronological history under statuses and each event mapped to parent_status. Subscribe to the parcel-status-changed webhook for push updates. Reference: Tracking parcels.
How do I create Deutsche Post return labels?
Deutsche Post returns are limited compared to parcel-focused carriers given the letter and small-goods focus. Warenpost shipments support return where the contract enables them; standard letter formats typically don't expose return services.
All return labels are created through Sendcloud's standalone v3 Returns API (synchronous or asynchronous; async is recommended for higher throughput). No outgoing parcel lookup or JWT tokens are required. Reference: Returns API overview.
How does Sendcloud's multi-carrier API compare to connecting carriers individually?
The Sendcloud REST API gives you access to 170+ carriers, including Deutsche Post, through one credential set, one schema, one webhook stream, and one error model. Connecting carriers individually means handling separate authentication, payload formats, and tracking systems for each, and redoing the work every time a carrier ships breaking changes upstream.
With Sendcloud, you ship Deutsche Post alongside DHL, Hermes, GLS, and DPD, or any other carrier in your account using the same code. Route shipments between carriers based on rules (weight, destination, service level, cost) without writing carrier-specific routing logic. Fall back to alternative carriers automatically if Deutsche Post's upstream system has issues.
Adding a new carrier later means adding it to your Sendcloud account, not building a new integration.
