Deutsche Post INTERNETMARKE Virtual Sandbox

Automate online postage generation and mail product management for Deutsche Post.

The INTERNETMARKE API allows developers to integrate Deutsche Post's online postage services directly into their applications. It supports managing shopping carts, generating postage labels in various formats like PNG and PDF, and handling user-specific postage configurations for mail products.

Use this hosted sandbox to simulate Deutsche Post INTERNETMARKE APIs without authentication, API keys, or extra dependencies. Point your code or SDK to the Beeceptor base URL, preferably through an environment variable or feature flag, and switch back to the production API when ready. This keeps your integration code consistent across local development, QA, demos, and production.

Use cases:

Use this sandbox to validate postage label generation workflows, shopping cart management, wallet balance checks, and PDF/PNG rendering logic. Developers can simulate successful label creation, handle order retrieval by ID, and test error responses for invalid mail product configurations before integrating with production postage services.

Deutsche Post INTERNETMARKE virtual sandbox is up and running!

Use this sandbox URL as the API base in your code to simulate Deutsche Post INTERNETMARKE responses instantly.
