Facebook Graph API not returning email

Question

I have the following code:

$fb = new Facebook([
    'app_id' => $appId,
    'app_secret' => $appSecret,
    'default_graph_version' => 'v2.9',
]);

$oAuth2Client = $fb->getOAuth2Client();
$tokenMetaData = $oAuth2Client->debugToken($accessToken);
dump($tokenMetaData);

$graphUser = $fb->get('/me?fields=first_name,last_name,email', $accessToken)->getGraphUser()->asArray();
dump($graphUser);

The output for the above is the following:

$metaData:

 [
   "app_id" => "..."
   "application" => "My App Name"
   "expires_at" => "2017-07-01 11:40:09.000000"
   "is_valid" => true
   "issued_at" => "2017-05-02 11:40:09.000000"
   "metadata" => array:2 [
     "auth_type" => "rerequest"
     "sso" => "ios"
    ]
    "scopes" => array:2 [
      0 => "email"
      1 => "public_profile"
    ]
    "user_id" => "102..."
  ]
}

$graphUser:

array:3 [
  "first_name" => "John"
  "last_name" => "Smith"
  "id" => "102...",
]

As you can see, the scopes in $metaData clearly has email so it isn't a permission issue. Despite this, the graph user sometimes does not have the email (although in some cases it does).

Why is this and how can I solve this issue?

The API will only returned confirmed email addresses. And there is a bunch of other factors such as privacy settings that can also influence this. So don’t write your app so that it _relies_ on getting an email address from the API. Lots of users don’t have one on file with Facebook, if they signed up using just their mobile. — CBroe, May 02 '17 at 12:30

@YahyaUddin, Also, there are lots of user who actually signed up from their mobile phones & they don't have an email at all on their account. Quite old yet, might help somebody — Kasun Rajapaksha, May 21 '21 at 05:29

Add the fields you need to the URL of your request:

https://graph.facebook.com/me?fields=email,name

One possibility which i came across today is, if i am registering a account where i am not logging in using my email ID, may be using mobile number to login, and even in my profile primary email is not set or set to a mobile number, in this case facebook returns null for email.

I have updated the account and added email to primary email field under settings in facebook page, then i was able to get the email id from facebook.

Hope this helps someone.

Happy coding...

First check if your access token gets the user's permission for the email

https://graph.facebook.com/me/permissions?
  access_token=(access-token)
  &debug=all

if in the answer, this content does not appear:

{
    "data": [
        {
            "permission": "email",
            "status": "granted"
        },
        {
            "permission": "public_profile",
            "status": "granted"
        }
    ]
}

Maybe in obtaining your access token I do not request mail ownership: Add scope=email to the request

https://www.facebook.com/v2.10/dialog/oauth?
  client_id=(app-id)
  &redirect_uri=(redirect-uri)
  &scope=email

You have to check these steps.

check if your access token gets the user's permission for the email . for that login to your developer account of your app, then tools->graph api explorer then enable user's permission for the email.
check the facebook version, use the latest version.

add email scope in face book login script as below

app.get(
    '/auth/facebook',
    passport.authenticate('facebook', {
      scope: ['user_location', 'email', 'user_friends']
    })
  );

or

FB.login(function(response) { 

   // your ajax script

},{
    scope: 'email', 
    return_scopes: true
});

Goto your app > App review > Permissions and Features

Request Advanced access for email which should turn Standard Access into Advanced Access

I solved this issue by specifying the graph api version.

My requested fields first_name,last_name,email,picture

To url: https://graph.facebook.com/me

Did NOT return email.

To url: https://graph.facebook.com/v2.9/me

Did return email.

Hope this helps.

I specified the version, so that does not seem to be the issue – Yahya Uddin May 31 '17 at 10:30
