title: Send surveymonkey web links via sms, enable respondent tracking
body: <p>We're trying to put together a survey solution which allows us to send links to our surveys to users via SMS.  I know we could simply take the surveymonkey survey url and send it, but we want the same unique respondent tracking that you get via email, so we can break down responses by respondent group. So to achieve that, every respondent would need a custom, trackable url for each survey.</p>
  
  <p>I see that when you send the survey via email, you get a unique link along the lines of <a href="https://www.surveymonkey.com/s.aspx?sm=cun03M8_2br9IdNcpt0CqL9A_3d_3d" rel="nofollow">https://www.surveymonkey.com/s.aspx?sm=cun03M8_2br9IdNcpt0CqL9A_3d_3d</a></p>
  
  <p>I also see in the api documentation for <code>get_respondent_list</code> that there's a field "recipient_id" which is described as "ID generated for recipients of survey invitations via email collectors".  It's not obvious from the unique email link if the link includes the survey id and the recipient id, or if it's just a "tracking code" which gets converted to an id later. So I'm just wondering if there's a way to programmatically generate the unique link for a given respondent?</p>
