title: Getting "The parameter app_id is required" with OAuth.io
body: <p>I am trying to integrate <a href="https://oauth.io/" rel="nofollow noreferrer">https://oauth.io/</a> into my application. Below is the code for facebook integration that I am using:</p>
  
  <pre><code> OAuth.popup('facebook')
              .done(function (result) {
                  alert('sucess');
              })
              .fail(function (error) {
                  alert('fail');
              });
  </code></pre>
  
  <p>Note: I am calling the above part of code in a button click.</p>
  
  <p>In JQuery ready function I am calling <code>OAuth.initialize("my_public_key");</code></p>
  
  <p>When I click on the button I am getting "The parameter app_id is required" error in the popup. (added image of it)</p>
