I’m accessing the facebook API with sdk javascript created my app, load window, logo and access, need the data now to send to the bank, I’m having difficulties in this, I asked in the script to bring the email for example and the return is Undefined: Thanks for logging in, xxx xxx email=undefinedniver=undefinedgenero=Undefined! Someone has some idea of how to solve, I’ll take the example I took on the face Velopers and added in the case the data I need.

  // This is called with the results from from FB.getLoginStatus().
  function statusChangeCallback(response) {
    console.log('statusChangeCallback');
    console.log(response);
    // The response object is returned with a status field that lets the
    // app know the current login status of the person.
    // Full docs on the response object can be found in the documentation
    // for FB.getLoginStatus().
    if (response.status === 'connected') {
      // Logged into your app and Facebook.
      testAPI();
    } else if (response.status === 'not_authorized') {
      // The person is logged into Facebook, but not your app.
      document.getElementById('status').innerHTML = 'Please log ' +
        'into this app.';
    } else {
      // The person is not logged into Facebook, so we're not sure if
      // they are logged into this app or not.
      document.getElementById('status').innerHTML = 'Please log ' +
        'into Facebook.';
    }
  }

  // This function is called when someone finishes with the Login
  // Button.  See the onlogin handler attached to it in the sample
  // code below.
  function checkLoginState() {
    FB.getLoginStatus(function(response) {
      statusChangeCallback(response);
    });
  }

  window.fbAsyncInit = function() {
  FB.init({
    appId      : 'xxx',
    cookie     : true,  // enable cookies to allow the server to access 
                        // the session
    xfbml      : true,  // parse social plugins on this page
    version    : 'v2.8' // use graph api version 2.8
  });

  // Now that we've initialized the JavaScript SDK, we call 
  // FB.getLoginStatus().  This function gets the state of the
  // person visiting this page and can return one of three states to
  // the callback you provide.  They can be:
  //
  // 1. Logged into your app ('connected')
  // 2. Logged into Facebook, but not your app ('not_authorized')
  // 3. Not logged into Facebook and can't tell if they are logged into
  //    your app or not.
  //
  // These three cases are handled in the callback function.

  FB.getLoginStatus(function(response) {
    statusChangeCallback(response);
  });

  };

  // Load the SDK asynchronously
  (function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_US/sdk.js";
    fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));

  // Here we run a very simple test of the Graph API after login is
  // successful.  See statusChangeCallback() for when this call is made.
  function testAPI() {
    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {
      console.log('Successful login for: ' + response.name);
/*  
email="+response.email+"niver="+response.birthday+"genero="+response.gender+"location"+response.location.name      
document.getElementById("name").value = response.name;
document.getElementById("email").value = response.email;
document.getElementById("birthday").value = response.birthday;
document.getElementById("gender").value = response.gender;
document.getElementById("location").value = response.location.name;
*/
      document.getElementById('status').innerHTML =
        "Thanks for logging in, " + response.name +" email="+response.email+"niver="+response.birthday+"genero="+response.gender+'!';
    });
  }
</script>

  Below we include the Login Button social plugin. This button uses

I was able to resolve passed the fields I need for the FB function. FB.api('/me', {Fields: 'name, email'}, Function(Response) { console.log('Successful login for: ' + Response.name); console.log(Response);
