title: Pass custom parameter when survey complete in survey monkey V3
body: <p>I am looking for a way to get back the custom parameter "name" that is used for storing Custom Data in the SurveyMonkey system when a user completes a survey, whether that be via the Embed OR WebLink.</p>
  
  <p>Any suggestions on how others have approached this?</p>
  
  <p>I already saw this <a href="https://stackoverflow.com/questions/21708582/can-the-surveymonkey-custom-parameter-be-passed-back-via-a-survey-complete-url">SO</a> But that is Version 2 in my case The  <code>get_respondent_list</code> is not in the Version 3 API. (Sorry for copy paste that same question but I am looking the same result in v3)</p>
  
  <p>And Any suggestion about add signature pad includes the every Survey.</p>
