kombit-client 1.1.3

KOMBIT client provides easy connection to webservices from KOMBIT / Serviceplatformen / digitaliseringskataloget.

kombit-client

A Python client for connecting to Danish government web services via KOMBIT Serviceplatformen. The package wraps a .NET library using pythonnet, exposing a clean Python API with Pythonic naming conventions.

Requirements

• Python 3.10–3.14
• .NET 9 runtime or SDK (download)
• Certificates issued by KOMBIT for STS and service authentication: digitaliseringskataloget - certifikater*

*Note: The “Den Danske Stat” root certificate must be installed in a trusted root certificate store (either the system or user trust store).

Installation

pip install kombit-client

Overview

All configuration can be handled via environment variables. You can set the following variables before using the service clients:

Environment Variable	Description
CVR_NUMBER	(Optional) Organisation's CVR number
CERT_BASE_PATH	(Optional) Directory containing all certificate files
CLIENT_CERT	(Optional) Filename of client certificate (e.g., client.p12)
CLIENT_CERT_BASE64	(Optional) Client certificate as a base64 string
CLIENT_CERT_PASS	(Optional) Password for client certificate
ROOT_CERT	(Optional) Filename of the root certificate (needs to be added to trust store)
ACCESS_CONTROL_CERT	(Optional) Filename of the STS/Access Control certificate
SP_SIGNING_CERT	(Optional) Filename of the "serviceplatformen" signing certificate
YDELSESINDEKS_CERT	(Optional) Filename of the "ydelsesindeks" signing certificate
STS_ENDPOINT_ADDRESS	(Optional) URL of the STS endpoint
STS_ENDPOINT_ID	(Optional) Entity identifier for the STS

Defaults certificate names are defined in the code for public shared certificates and are based on current (2026-04-24) certificate names from serviceplatformen's production environment. All certificate paths are constructed as os.path.join(CERT_BASE_PATH, <filename>).

All configurations can also be set when initiating the service clients. Some service clients might require additional configuration passed at initialization.
