WS-Addressing (WSA)

New in version 0.15.

Zeep offers (experimental) support for the ws-addressing specification. The specification defines a number of soap:Header elements which basically allows advanced routing of the SOAP messages.

If the WSDL documnt defines that WSA is required then Zeep will automatically add the required headers to the SOAP envelope. In case you want to customize this then you can add the WsAddressPlugin to the Client.plugins list.

For example:

from zeep import Client
from zeep.wsa import WsAddressingPlugin

client = Client(


The support for ws-addressing is experimental. If you encounter any issues then please don’t hesistate to create an issue on the github repository.
