title: What is the postman-token header attribute in generated code from Postman?
body: <p>I have been using postman to explore a REST interface. When using Postman's code generation feature, regardless of which programming language I select,  Postman will always add a <code>postman-token</code> attribute in the header. Why is it there?</p>
  
  <p>See for example PHP Curl:</p>
  
  <pre><code>&lt;?php
  
  $curl = curl_init();
  
  curl_setopt_array($curl, array(CURLOPT_URL =&gt; "https://myURL.com,
  CURLOPT_RETURNTRANSFER =&gt; true,
  CURLOPT_ENCODING =&gt; "",
  CURLOPT_MAXREDIRS =&gt; 10,
  CURLOPT_TIMEOUT =&gt; 30,
  CURLOPT_HTTP_VERSION =&gt; CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST =&gt; "GET",
  CURLOPT_HTTPHEADER =&gt; array(
    "authorization: Basic abcdefghijklmnop",
    "cache-control: no-cache",
    "postman-token: wt53gwg-e9bb-645d-g53d-e42f8765aut0"
    ),
  ));
  $response = curl_exec($curl);
  $err = curl_error($curl);
  curl_close($curl);
  if ($err) {
    echo "cURL Error #:" . $err;
  } else {
    echo $response;
  }
  </code></pre>
