Facebook api not returning friends contact info - facebook

Question

In my contacts manager app, I need to have an option to import contacts from facebook. Im using hello.js This is the function
function getFriends(network, path){
var list = document.getElementById('list');
list.innerHTML = '';
// login
hello.login( network, {scope:'friends'}, function(auth){
if(!auth||auth.error){
console.log("Signin aborted");
return;
}
// Get the friends
// using path, me/friends or me/contacts
hello( network ).api( path , function responseHandler(r){
for(var i=0;i<r.data.length;i++){
var o = r.data[i];
var li = document.createElement('li');
var ph = "";
if(o.gd$phoneNumber != undefined)
{
for (var j = 0; j <= o.gd$phoneNumber.length; j++ ) {
if(o.gd$phoneNumber[j] != undefined)
{
//console.log(o.gd$phoneNumber[j].$t);
ph += o.gd$phoneNumber[j].$t +'<br>';
}
};
}
li.innerHTML = o.name + (o.thumbnail?" <img src="+o.thumbnail+" />":'') +' Phone : '+ph;
list.appendChild(li);
};
});
});
}
The function is invoked by getFriends('facebook','me/friends') .This only returns the count of friends like this
{
"data": [
],
"summary": {
"total_count": 1076
}
}
but by using getFriends('facebook','me/taggable_friends'), I'm getting the name and image of the friends but not any email id or contact number.
Can anyone figure out the issue ?

Answer 1

/me/taggable_friends is ONLY for getting tagging tokens (you don´t get User IDs), and ONLY for tagging your friends (in status posts, for example).
/me/friends only returns friends who authorized your App too, that´s intentional. Users who don´t use your App don´t show up for privacy reasons.
That being said, even if you would be able to get ALL friends, you can´t get any details like email and especially not a contact number. You can´t even get the phone number from the authorized User.
