Hello @ll, I'm fairly new to SOAP and I've been trying to solve this issue with no succeed so far. The service administrator asks me for a Username Token with digest password inside the header. I have this example of implementation: <soapenv:Header> <wsse:Security xmlns:wsse=" http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext... soapenv:mustUnderstand="1"> <wsse:UsernameToken xmlns:wsu=" http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utilit... wsu:Id="UsernameToken-32685187"> <wsse:Username>nomUsuari</wsse:Username> <wsse:Password Type=" http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-pr... ">kfKGwLQVEAI98vcQLAqvFcASPSI=</wsse:Password> <wsse:Nonce>9LoOwjIQMTA5hkFKOWTk5A==</wsse:Nonce> <wsu:Created>2008-07-23T09:44:42.242Z</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soapenv:Header> How can I manage this in Suds? I've done this code for the auth. part, based on previous emails on this list: url='http://url.cat?wsdl' client=Client(url) baseurl='http://url.cat/' username='username' password='password' passman=urllib2.HTTPPasswordMgrWithDefaultRealm() passman.add_password(None, baseurl, username, password) authhandler=urllib2.HTTPDigestAuthHandler(passman) client.options.transport.urlopener=urllib2.build_opener(authhandler) but I do not know how to manage to include it in the header. I get this error message: suds.WebFault: Server raised fault: 'WSDoAllReceiver: Request does not contain required Security header' Any help would be really appreciate. Thank you!
