Facebook Doesn't Return Email Python Social Auth

Question

here's my pipeline in settings.py:

SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'accounts.pipeline.create_user',
    'accounts.pipeline.update_user_social_data',
    # 'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details',
)

along with this line:

SOCIAL_AUTH_FACEBOOK_SCOPE = ['email']

I tried this as well:

FACEBOOK_EXTENDED_PERMISSIONS = ['email']

and in my pipeline.py:

def create_user(strategy, details, user=None, *args, **kwargs):
    if user:
        return {
            'is_new': False
        }

    fields = dict((name, kwargs.get(name) or details.get(name))
                  for name in strategy.setting('USER_FIELDS',
                                               USER_FIELDS))

    if not fields:
        return

    if strategy.session_get('signup') == 'UserType1':
        user1 = UserType1.objects.create_user(username=fields.get('username'))
        user1.user_type = User.USERTYPE1
        user1.save()

        return {
            'is_new': True,
            'user': user1
        }

    elif strategy.session_get('signup') == 'UserType2':
        user2 = UserType2.objects.create_user(username=fields.get('username'))
        user2.user_type = User.USERTYPE2
        user2.save()

        return {
            'is_new': True,
            'user': user2
        }


def update_user_social_data(strategy, *args, **kwargs):
    if not kwargs['is_new']:
        return

    full_name = ''
    backend = kwargs['backend']

    user = kwargs['user']

    full_name = kwargs['response'].get('name')
    user.full_name = full_name

    email = kwargs['response'].get('email')
    user.email = email

    user.save()

However, kwargs['response'].get('name') returns user's full name correctly, but kwargs['response'].get('email') is always none. When I do print kwargs['response'], it only shows uid and the name of the user as well, so Facebook doesn't return user's email. How to overcome this? Thanks!

I think this might be due to changes in Facebook's Graph API v2.4.

In previous versions of the API, adding

SOCIAL_AUTH_FACEBOOK_SCOPE = ['email']

would allow you to get the facebook user's email. Now, that is not sufficient and kwargs['response'].get('email') is blank.

However, as explained in python social auth issue 675, also adding this

SOCIAL_AUTH_FACEBOOK_PROFILE_EXTRA_PARAMS = {
    'fields': 'id,name,email', 
}

to your settings seems to get around this problem and you can get the user's email again.

It is true that it was due to the changes in the API, but that didn't work for me as well. I had to make another request like I wrote in my answer. Thanks anyways, I appreciate it. — Hasan Can Saral, Aug 20 '15 at 23:05

Apparently you need to make another request like following (again in social pipeline):

def update_user_social_data(strategy, *args, **kwargs):
    if not kwargs['is_new']:
        return

    user = kwargs['user']

    fbuid = kwargs['response']['id']
    access_token = kwargs['response']['access_token']

    url = u'https://graph.facebook.com/{0}/' \
          u'?fields=email' \
          u'&access_token={1}'.format(
        fbuid,
        access_token,
    )

    request = urllib2.Request(url)
    email = json.loads(urllib2.urlopen(request).read()).get('email')

    user.email = email
    user.save()

this may not work all the time since email is not a mandatory field for having a Facebook account. For creating a Facebook account you need one but not necessarily both of email and mobile – Sagnik Sinha Jan 02 '16 at 09:36

It is possible that a user decides not to give away his/her email address on the permission access dialog, you can check kwargs['response']['granted_scopes'] and kwargs['response']['denied_scopes'] for references. To prompt user again for email, you can add SOCIAL_AUTH_FACEBOOK_AUTH_EXTRA_ARGUMENTS = {'auth_type': 'rerequest'} to settings.py.

Facebook does not sends email-ids to localhost:8000. Check out the documentation here: python-django social auth for FB
