A Python SOAP client

Highlights:

• Compatible with Python 3.7, 3.8, 3.9, 3.10, 3.11 and PyPy3
• Build on top of lxml, requests and httpx
• Support for Soap 1.1, Soap 1.2 and HTTP bindings
• Support for WS-Addressing headers
• Support for WSSE (UserNameToken / x.509 signing)
• Support for asyncio using the httpx module
• Experimental support for XOP messages

Please see for more information the documentation at http://docs.python-zeep.org/

Status

I consider this library to be stable. Since no new developments happen around the SOAP specification it won't be updated that much. Good PR's which fix bugs are always welcome however.

Installation

Note that the latest version to support Python 2.7, 3.3, 3.4 and 3.5 is Zeep 3.4, install via pip install zeep==3.4.0

Zeep uses the lxml library for parsing xml. See https://lxml.de/installation.html for the installation requirements.

Usage

from zeep import Client

client = Client('tests/wsdl_files/example.rst')
client.service.ping()

To quickly inspect a WSDL file use:

python -m zeep <url-to-wsdl>

To connect with the KvK SOAP Dataservice (https://www.kvk.nl/producten-bestellen/handelsregister-dataservice/aansluitendataservice/overheid/aansluiten/) you can use the following code. This will connect with the preproduction server with test data only. You will need a valid public/private key pair that is registered also on the KvK side. Furthermore, you need to combine their public certificates into one .cer file so it can be used to verify the responses you get back from their server.

Different products are on different WSDL's with different WS-A addressed, so update accordingly. A list of product can be found on the given URL, together with their public certificates and a lot of other technical info.
