any appreciated. thank you.

the soapaction should have method , in instance of following per wsdl used above.

http://entrader.contigoenergy.com/contigo.entrader.service/tradingservice/gettrade

http://entrader.contigoenergy.com/contigo.entrader.service/tradingservice/getbyfiltertrade

so, new code should following

h=basictextgatherer() headerfields =     c(c(accept="text/xml", accept="multipart/*",         'content-type' = "text/xml; charset=utf-8"),       soapaction = "http://entrader.contigoenergy.com/contigo.entrader.service/tradingservice/gettrade")  body = '<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"   xmlns:con="http://entrader.contigoenergy.com/contigo.entrader.service">\     <soapenv:header>\ <wsse:security soapenv:mustunderstand="1"\ xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">\ <wsse:usernametoken wsu:id="usernametoken-37"\ xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">\ <wsse:username>username</wsse:username>\ <wsse:password type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#passwordtext">password</wsse:password>\ </wsse:usernametoken>\ </wsse:security>\ </soapenv:header>\ <soapenv:body>\ </soapenv:body>\ </soapenv:envelope>\n'  curlperform(url = "https://ngcsi.contigohosting.com/entrader_dev/wcfservices/tradingservice.svc",             httpheader = headerfields,             postfields = body,              writefunction = h$update,             verbose=true )  body=h$value()

the above code works , able appropriate response webservice although have not mentioned in body in example stated.
