20012 - Request not understood from C .Net

[Anonymous]

Hi All,

We are receiving error messages from the Marketo API about our XML/SOAP message format being misunderstood, "Request does not appear to conform to WSDL (20012)" is the response message. We load the web service WSDL through .Net and it generates the XML for us automatically when we call the syncLead method. Our code was working with the API version 1.6 up until the 12th December, we've since tried API versions 2.1 and 2.2 with the same result. Can anyone suggest a fix? I've seen a few similar posts but people have taken it offline and sorted it out directly with Marketo so they haven't posted a fix.

Adding a small detail to your Support Case...

The XML request is missing the target workspace, a required parameter 

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:mkt="http://www.marketo.com/mktows/">

   <soapenv:Header>

      <mkt:MktowsContextHeader>

         <targetWorkspace>Default</targetWorkspace>

      </mkt:MktowsContextHeader>

You have a malformed XML. The Marketo cookie value is not properly escaped.

MktowsContextHeader is not requiried unless you wish to target a specific Workspace in Marketo.
