Как я могу получить профиль пользователя на battle.net oauth

Я пытаюсь войти с Blizzard ID на моем сайте.
Я думаю, что мой код работает. Запрос профиля пользователя не выполнен.
Я не понимаю профиль пользователя Blizzard. Структура данных.
Можете ли вы помочь мне получить идентификатор пользователя, адрес электронной почты и боевой тег?

Вот мой код

<?php
class Hybrid_Providers_Kakao extends Hybrid_Provider_Model_OAuth2
{
/**
* initialization
*/
function initialize()
{
parent::initialize();

// Provider API end-points
$this->api->api_base_url  = "https://kr.api.battle.net/";
$this->api->authorize_url = "https://kr.battle.net/oauth/authorize";
$this->api->token_url     = "https://kr.battle.net/oauth/token";

// redirect uri mismatches when authenticating with Battle.
if (isset($this->config['redirect_uri']) && !empty($this->config['redirect_uri'])) {
$this->api->redirect_uri = $this->config['redirect_uri'];
}
}

/**
* finish login step
*/
function loginFinish()
{
$error = (array_key_exists('error', $_REQUEST)) ? $_REQUEST['error'] : "";
// check for errors
if ( $error ){
throw new Exception( "Authentication failed! {$this->providerId} returned an error: $error", 5 );
}
// try to authenicate user
$code = (array_key_exists('code', $_REQUEST)) ? $_REQUEST['code'] : "";
try{
$this->authenticate( $code );
}
catch( Exception $e ){
throw new Exception( "User profile request failed! {$this->providerId} returned an error: $e", 6 );
}
// check if authenticated
if ( ! $this->api->access_token ){
throw new Exception( "Authentication failed! {$this->providerId} returned an invalid access token.", 5 );
}
// store tokens
$this->token("access_token",  $this->api->access_token);
$this->token("refresh_token", $this->api->refresh_token);
$this->token("expires_in",    $this->api->access_token_expires_in);
$this->token("expires_at",    $this->api->access_token_expires_at);
// set user connected locally
$this->setUserConnected();
}

/**
* load the user profile
*/
function getUserProfile()
{

$this->api->decode_json = false;
$this->api->curl_header = array( 'Authorization: Bearer ' . $this->api->access_token );

$data = $this->api->api("account/profile", "POST");

if ( ! isset( $data->id ) ) {
throw new Exception("User profile request failed! {$this->providerId} returned an invalid response.", 6);
}
# store the user profile.
$this->user->profile->identifier  = @ $data->id;
$this->user->profile->displayName = @ $data->battletag;
return $this->user->profile;
}

private function authenticate($code)
{
$params = array(
"response_type" => $code,
"grant_type"    => "authorization_code",
"client_id" => $this->api->client_id,
"redirect_uri" => $this->api->redirect_uri,

"scope" => "sc2.profile",
);

if( $this->api->client_secret && ($this->api->client_secret !== $this->api->client_id) ){
$params['client_secret'] = $this->api->client_secret;
}

$response = $this->request($this->api->token_url, $params, $this->api->curl_authenticate_method);
$response = $this->parseRequestResult($response);
if ( ! $response || ! isset($response->access_token) ) {
throw new Exception("The Authorization Service has return: " . $response->error);
}

// calculate when the access token expire
if ( isset($response->expires_in) ) {

}

return $response;
}

private function request($url, $params=false, $type="GET")
{
if(Class_exists('Hybrid_Logger')){
Hybrid_Logger::info("Enter OAuth2Client::request( $url )");
Hybrid_Logger::debug("OAuth2Client::request(). dump request params: ", serialize( $params ));
}
$this->http_info = array();
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL           , $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT       , $this->api->curl_time_out);

if ( $this->api->curl_proxy ) {

}
if ( $type == "POST" ) {
curl_setopt($ch, CURLOPT_POST, 1);
if ($params) curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query($params) );
}

return $response;
}

private function parseRequestResult($result)
{
if ( json_decode($result) ) return json_decode($result);
parse_str( $result, $ouput );
$result = new StdClass();
foreach( $ouput as $k => $v )
$result->$k = $v;

return $result;
}
}

Я думаю, что этот код не может прочитать идентификатор пользователя

    $this->user->profile->identifier  = @ $data->id;
$this->user->profile->displayName = @ $data->battletag;

на этой части.

Это не чистый HybridAuth.
