title: Getting Facebook Access Token from User Id and Facebook App Secret?
body: <p>I'm trying to understand how the facebook api works. The end goal is to be able to read the posts from a facebook page.</p>
  
  <p>If someone has connected with my app on facebook can my c# application then get the posts from a public facebook page if it knows their facebook account id (and has the facebook app secret hard coded).</p>
  
  <p>If so what are the http requests it needs to make in order to get the access token which can then be used to get the posts, and what are the requests to get a new access token before one expires?</p>
  
  <p>If you could provide an example in c# (maybe using the acebooksdk.net library) that would be great!</p>
  
  <p>Thanks.</p>
