title: Apple Wallet Authentication Token with special word
body: <p>This question is related to pass update.</p>
  
  <p>Since the .pkpass file send out to customers, we never know they open the pass in which method. For getting the return header of authorization, I use the keywords '<strong>ApplePass</strong> ' as begin, after the testing in a short time, some of them may using '<strong>AttidoPass</strong> ' or '<strong>AndroidPass</strong> ' to return the authorization token.　<strong>However, it is hard to find out user how to install the .pkpass .</strong></p>
  
  <p>In today case, a 'boarding pass' try to update pass, but there is no any header value when it call the web service. </p>
  
  <p><strong>Anybody know what method for that user update pass?</strong></p>
