title: How to get geo location and venue id of a checkin tweet posted onTwitter
body: <p>There are thousands 4sq checkin tweets posted on Twitter. These tweets all contain a link to foursquare.com.</p>
  
  <p>The link, for example, <a href="https://foursquare.com/donnyndra/checkin/4f60500ae4b02a8707007b93?s=ogf_jvcuoha1T0QUfIRVWGupvuc&amp;ref=tw" rel="nofollow">https://foursquare.com/donnyndra/checkin/4f60500ae4b02a8707007b93?s=ogf_jvcuoha1T0QUfIRVWGupvuc&amp;ref=tw</a>, has a checkin id and a signature.</p>
  
  <p>I read <a href="http://%20down%20vote%20accept%20Make%20an%20API%20request%20to%20get%20checkin%20details%3a%20https://developer.foursquare.com/docs/checkins/checkins" rel="nofollow">API doc</a> in 4sq.com, and found that <strong>an acting user is needed</strong> if I want to make Check-in Details request.</p>
  
  <p>Does this means that I have to let the user who made the checkin auth my app for access? <strong>But</strong> I collected thousands checkin tweets just for research and can not let 4sq.com users auth. </p>
  
  <p>Are there any solution to solve this problem? 
  What I only have:</p>
  
  <ul>
  <li>checkin id and signature</li>
  <li>client_id and client_secret</li>
  </ul>
  
  <p>Since I have links of checkins, should I parse the page behind the link to get what I want? Any better way to do it? Java language is used in my research project.</p>
  
  <p>I really really  need your kind help! Thanks in advance !</p>
