title: Google Apps Scripting Error: ReferenceError: "URLFetchApp" is not defined
body: <p>Working with a version of the following code in Google Apps Script.  I have verified the connection string works.  It seems to work until it hits the UrlFetchApp and then it throws the  "ReferenceError: "URLFetchApp" is not defined" error.  Any ideas/suggestions?  New to Google Apps Scripting.</p>
  
  <pre><code>function getMemo(){
  // url
  var url='someUrl'
  
  // parameters for the request
  var apiParams={
  'RequestType':'Memo',
  'TokenID':TOKEN,
  'MemoID':'3'
  };
  
  // encode the parameters correctly
  var encParams = toHtmlQuery_(apiParams);
  Logger.log(encParams);
  
  // construct the fetch params object
  var params={
  'method':'GET',
  'muteHttpExceptions':true
  };
  
  var response=URLFetchApp.fetch(url+encParams,params)
  
  function toHtmlQuery_(obj) {return "?"+Object.keys(obj).reduce(function(a,k){a.push(k+'='+encodeURIComponent(obj[k]));return a},[]).join('&amp;')};
  </code></pre>
