eBay SOAP API – Missing SOA operation name header – Ebay API

I am trying to invoke eBay’s findItemsByKeywords method and I get

Server raised fault: ‘Missing SOA operation name header’

My code is following:

from config import *

# url = 'http://developer.ebay.com/webservices/latest/ebaySvc.wsdl'
# url = 'http://svcs.ebay.com/services/search/BestMatchItemDetailsService/v1?wsdl'
url = 'http://developer.ebay.com/webservices/finding/latest/FindingService.wsdl'

from suds.client import Client
import logging
logging.basicConfig()
client = Client(url)

from suds.sax.element import Element
ns1 = ('ns1', 'http://www.ebay.com/marketplace/search/v1/services')
app_id = Element('X-EBAY-API-APP-ID', ns = ns1).setText(EBAY_API_APP_ID)
operation_name = Element('X-EBAY-SOA-OPERATION-NAME', ns = ns1).setText('findItemsByKeywords')
api_version = Element('X-EBAY-API-VERSION', ns = ns1).setText(EBAY_APP_VERSION)
site_id = Element('X-EBAY-API-SITE-ID', ns = ns1).setText(EBAY_API_SITE_ID)
encoding = Element('X-EBAY-API-REQUEST-ENCODING', ns = ns1).setText('SOAP')
service_name = Element('X-EBAY-SOA-SERVICE-NAME', ns = ns1).setText('FindingService')
client.set_options(soapheaders = [app_id, operation_name, api_version, site_id, encoding, service_name]) 

print client.service.findItemsByKeywords(keywords = 'book')

It prints:

    Use ebay-python, unofficial python wrapper for eBay API. It’s dead easy to use and it works. You can also see the source code on how to construct the request if you want to use your own.

    I was getting this error with some vb.net code trying to do the same thing and it turned out to be that I was simply using the wrong AppID. I was using the live one with the sandbox url, switched it and it was fine.

    I used this code and it works

    headers={'X-EBAY-SOA-OPERATION-NAME':'findItemsByKeywords',
                'X-EBAY-SOA-SECURITY-APPNAME': 'your-key'}

client = Client(url,headers=headers)
