    {client_id: APP_ID, client_         


        

Answer 1

check if users of the node.js or the JAVASCRIPT.

getLongLiveToken: function(data){
    FB.api('oauth/access_token', {
        client_id: data.client_id, // FB_APP_ID
        client_secret: data.secret, // FB_APP_SECRET
        grant_type: 'fb_exchange_token',
        fb_exchange_token: data.access_token // USER_TOKEN
    }, function (res) {
        if (!res || res.error) {
            console.log(!res ? 'error occurred' : res.error);
        } else {
            var accessToken = res.access_token;
            if(typeof accessToken != 'undefined'){}
        }
    });
}
