A new library provides simple client functionality to send and receive eDelivery AS4 messages using the Python language and the Domibus eDelivery AS4 gateway implementation.

The main objective of this library is to support prototyping implementations of the Once-Only Technical System developed for the EU's Single Digital Gateway regulation.

But the library is generic and can also be used in other contexts. Using this library, you can start sending and receiving eDelivery messages from applications within minutes.
