Webserivce call to update resource using PSI project server 2013

I would like a sample xml payload that I can use to call the update resource operation via the webservice api.

all the attempts that I have mde have not worked.

Here is one that I have tried

<soapenv:Envelope xmlns:soapenv=".." xmlns:res="..">

   <soapenv:Header/>

   <soapenv:Body>

      <res:UpdateResources>

         <!--Optional:-->
