title: Add Accept header to JQuery AJAX GET (via JSONP) request
body: <p>I'm trying to add an accept header to a jQuery AJAX GET request which uses the "jsonp" <code>dataType</code>, but for some reason it's not working.  Here's my code thus far.</p>
  
  <pre><code>var e4json =  JSON.stringify( { 
                    "thomas_smith106"           : "Daniel244", 
                    "transaction_type"          : "34",
                    "transaction_tag"           : "902006933",
                    "authorization_num"         : "ET4653",
                    "amount"                    : "15.75"
                } ); 
  
  $.ajax ({
      url: "https://api.demo.globalgatewaye4.firstdata.com",
      type: "GET",
      headers : {
          'accepts' : 'application/json'
      },
      data: e4json,
      dataType: "jsonp",
      success: function  (response) {
          alert('Successfuly called the e4 gateway api');
      }
  });
  </code></pre>
  
  <p>I've tried multiple things but nothing seems to be working.  I looked at the the documentation on the <a href="http://api.jquery.com/jQuery.ajax/" rel="nofollow">jQuery</a> site, but I'm not able to find any good examples.</p>
  
  <p>This is what I get for my request headers.  I need the accept header to be 'application/json'.</p>
  
  <pre><code>Accept:*/*
  Accept-Encoding:gzip,deflate,sdch
  Accept-Language:en-US,en;q=0.8
  Connection:keep-alive
  Cookie:_fd_session=d69310c5cd4a02a4700b5ba63f0d0c9b
  Host:api.demo.globalgatewaye4.firstdata.com

  <p>Any help would be awesome.  Thanks!</p>
