title: get Entry ID which is used to pre-populate fields (Items) in a Google Form URL
body: <p><em>NOTE: This question is <strong>not</strong> about finding ID of an Item (form element), but an ID of Entry. These are different things. Entry ID is a number which is used to pre-populate fields (Items) in a form URL.</em></p>
  
  <p>As described here <a href="https://developers.google.com/apps-script/reference/forms/text-item" rel="nofollow noreferrer">https://developers.google.com/apps-script/reference/forms/text-item</a> it is possible to get a TextItem ID (actually, any Item ID) via <code>getID()</code> method.</p>
  
  <p>If you open any public Google Form HTML source code you will see something like this in the <code>var FB_PUBLIC_LOAD_DATA</code>:</p>
  
  <pre><code>[232495719,"Question 1",null,0,[[1492883199]]
   ^                               ^
   Item ID                         Entry ID
  </code></pre>
  
  <p>I don't see a method to get <strong>Entry IDs</strong>. Is it actually possible to do via Google Apps Script API?</p>
