title: Searching the LinkedIn API without authorizing a user
body: <p>Im currently creating a PHP application that searched various Social Media and analyses the results. Now im stuck at calling the LinkedIn API. </p>
  
  <p>I need to call these API's without user authentication (I need a sort of app authentication). Facebook offers a way to retrieve an access token, based on app key and secret. With Twitter I simply used my own accestoken en access secret.</p>
  
  <p>I searched all day for a way to call the LinkedIn API in a similar way, but havent succeeded in finding one. I also couldn't find my own access token en secret on the LinkedIn developer's site.</p>
  
  <p>Do you know how I can access the LinkedIn API from my PHP application, without the user having to login himself?</p>
  
  <p>Hope you guys can help me out!</p>
