Dump SOAP Request and Response Messages

This section provides a tutorial example on how to dump SOAP request and response messages with the Zeep Python library.

If you are using Zeep Python library to invoke SOAP Web service operations, Zeep will take your input parameters and convert them into a SOAP request message and post it to the server.

When Zeep receives the SOAP response message, it will convert the message into a result value for you, as shown in the previous tutorial.

If you want to get a copy of the SOAP request and response messages, you can turn on the logging option at the DEBUG level as shown in this Python script example:

#- Dump_SOAP_Messages.py
#- Copyright (c) 2019 HerongYang.com. All Rights Reserved.
from zeep import Client
import logging.config

    'version': 1,
    'formatters': {
        'verbose': {
            'format': '%(name)s: %(message)s'
    'handlers': {
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'verbose',
    'loggers': {
        'zeep.transports': {
            'level': 'DEBUG',
            'propagate': True,
            'handlers': ['console'],

wsdl = "https://www.herongyang.com/Service/Hello_WSDL_11_SOAP.wsdl"

client = Client(wsdl)
result = client.service.Hello("Hello from client.")

Run the test script to see the SOAP request and response messages in the logging output:

herong$ python3 Dump_SOAP_Messages.py 

zeep.transports: Loading remote data from: 

Forcing soap:address location to HTTPS
zeep.transports: HTTP Post to 

<?xml version='1.0' encoding='utf-8'?>
        Hello from client.

zeep.transports: HTTP Response from 
  https://www.herongyang.com/Service/Hello_SOAP_11.php (status: 200):

      Hello from server - herongyang.com.

      Hello from server - herongyang.com.
