OverallStatus Error

Question

Based on this question I a trying to get a list of my Salesforce Marketing Cloud DataExtensions using the following XML in SoapUI (auth added automatically)

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:par="http://exacttarget.com/wsdl/partnerAPI">
     <soapenv:Body>
        <RetrieveRequestMsg xmlns="http://exacttarget.com/wsdl/partnerAPI">
           <RetrieveRequest>
              <ObjectType>DataExtension</ObjectType>
              <Properties>CustomerKey</Properties>
              <Properties>Name</Properties>
              <Properties>CategoryID</Properties>
           </RetrieveRequest>
        </RetrieveRequestMsg>
     </soapenv:Body>
</soapenv:Envelope>

Whatever I do, the response has the very helpful OverallStatus message 'Error'. No error code or description.

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

         </wsu:Timestamp>
      </wsse:Security>
   </soap:Header>
   <soap:Body>
      <QueryResponseMsg xmlns="http://exacttarget.com/wsdl/partnerAPI">
         <OverallStatus>Error</OverallStatus>

      </QueryResponseMsg>
   </soap:Body>
</soap:Envelope>

Two questions:

1. What am I doing wrong?
2. Any way to get a more expressive error message? Error is not helpful.

Answer 1

OK sorted. Cause: User error.

I didn't understand that the 'folders' in SoapUI have significance. They set the SOAPAction header. I'd put my RetrieveRequest in the Query folder, when it needed to be the Retrieve folder.

Lesson learned!

Answer 2

I am doing it using the fueloauth param, ie:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:par="http://exacttarget.com/wsdl/partnerAPI">
   <soapenv:Header>
   <fueloauth xmlns="http://exacttarget.com">YOUR TOKEN</fueloauth>
  </soapenv:Header>
   <soapenv:Body>
      <RetrieveRequestMsg xmlns="http://exacttarget.com/wsdl/partnerAPI">
         <RetrieveRequest>
            <ObjectType>DataExtension</ObjectType>
            <Properties>Name</Properties>     
            <Properties>CustomerKey</Properties>         
        </RetrieveRequest>
      </RetrieveRequestMsg>
   </soapenv:Body>
</soapenv:Envelope>

I think you should add the header with the token or the username/token header:

<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>
             <wsse:Username>YOUR USERNAME</wsse:Username>
            <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">YOUR PASSWORD_</wsse:Password>
         </wsse:UsernameToken>
      </wsse:Security>
   </soapenv:Header>
