Error making call "Invalid multi part request" Docusign API

Question

I am new to API's in general and I was hoping to get another pair of eyes on this. I have a document I am sending through the call and want to apply a template I've created. Everything worked until I tweaked the XML to handle the composite template. I'm not sure if there is something wrong with the nested information. If I have it in an improper sequence. Any help you all are willing to lend is much appreciated.

 string xmlBody =
                    "<envelopeDefinition xmlns=\"http://www.docusign.com/restapi\">" +
                   "<emailSubject>Docusign this Document</emailSubject>" +
                    "<status>Sent</status>" +
                    "<compositeTemplates>" +
                    "<compositeTemplate>" +
                        "<serverTemplates>" +
                        "<serverTemplate>" +

When posting questions it is helpful to share the specific XML/JSON of the HTTPS request including the headers and endpoint that you are calling. You should ALSO post specific error messages/response messages that you receive from the API call.

What it looks like is you are not creating a multipart request in fact. Please share the SOAP header/endpoint and the actual raw XML (not the stringify code) so that the error can be identified. Thanks! Paul
