Automated letter dispatch via API — straight from your system

Integrate dispatch through a flexible API interface

With our REST API you send your letters as PDF files straight from your software or web application — secure, fast and without manual steps.

REST APIs make it easy to exchange and process data between systems. For largely automated processes an API connection is especially worthwhile.
