Facebook Auth with AngularJS and Django REST Framework

I am developing a SPA application with AngularJS which uses Django backend for the server. The way that I communicate with the server from the SPA is with django-rest-framework. So now I want to make authentication with facebook (google and twitter too) and I read a lot on this topic and found OAuth.io which is making the authetication on the client SPA side and python-social-auth which is doing the same thing but on the server side.

So currently I have only the client auth, my app is connecting to facebook (with OAuth.io) and login successfully. This process is returning access_token and then I am making a request to my API which have to login this user or create account for this user by given token and this part is not working. So I am not sure where I am wrong, maybe because there isn't a full tutorial about using python-social-auth so maybe I am missing something or.. I don't know..

So some code of this what I have:

On the SPA side: This is the connection with OAuth.io and is working because I am getting the access token. Then I have to make a request to my rest API. backend is 'facebook', 'google' or 'twitter'

OAuth.initialize('my-auth-code-for-oauthio');
OAuth.popup(backend, function(error, result) {
    //handle error with error
    //use result.access_token in your API request

    var token = 'Token ' + result.access_token;
    var loginPromise = $http({
         method:'POST', 
         url: 'api-token/login/' + backend + '/', 
         headers: {'Authorization': token}});

         loginPromise.success(function () {
             console.log('Succeess');
         });
         loginPromise.error(function (result) {
             console.log('error');
         });
});

On the server in my settings.py I have added social plugin to the installed apps, template context preprocessors, some auth backends and that is my file:

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    ...,
    'rest_framework',
    'rest_framework.authtoken',
    'api',
    'social.apps.django_app.default',
    'social'
)
TEMPLATE_CONTEXT_PROCESSORS = ("django.contrib.auth.context_processors.auth",
                               "django.core.context_processors.debug",
                               "django.core.context_processors.i18n",
                               "django.core.context_processors.media",
                               "django.core.context_processors.static",
                               "django.core.context_processors.request",
                               "django.contrib.messages.context_processors.messages",
                               'social.apps.django_app.context_processors.backends',
                               'social.apps.django_app.context_processors.login_redirect',)

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.TokenAuthentication',
    )
}

SOCIAL_AUTH_FACEBOOK_KEY = 'key'
SOCIAL_AUTH_FACEBOOK_SECRET = 'secret'
SOCIAL_AUTH_FACEBOOK_SCOPE = ['email']

AUTHENTICATION_BACKENDS = (
      'social.backends.open_id.OpenIdAuth',
      'social.backends.facebook.FacebookOAuth2',
      'social.backends.facebook.FacebookAppOAuth',
      'social.backends.google.GoogleOpenId',
      'social.backends.google.GoogleOAuth2',
      'social.backends.google.GoogleOAuth',
      'social.backends.twitter.TwitterOAuth',
      'django.contrib.auth.backends.ModelBackend',
  )

In my views.py of the API I have the following (I found it here):

from django.contrib.auth.models import User, Group
from rest_framework import viewsets, generics
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import authentication, permissions, parsers, renderers
from rest_framework.authtoken.serializers import AuthTokenSerializer
from rest_framework.decorators import api_view, throttle_classes
from social.apps.django_app.utils import strategy
from rest_framework.permissions import IsAuthenticated, IsAuthenticatedOrReadOnly

from django.contrib.auth import get_user_model
from django.db.models.signals import post_save
from django.dispatch import receiver
from rest_framework.authtoken.models import Token

class ObtainAuthToken(APIView):
    throttle_classes = ()
    permission_classes = ()
    parser_classes = (parsers.FormParser, parsers.MultiPartParser, parsers.JSONParser,)
    renderer_classes = (renderers.JSONRenderer,)
    serializer_class = AuthTokenSerializer
    model = Token

    # Accept backend as a parameter and 'auth' for a login / pass
    def post(self, request, backend):
        serializer = self.serializer_class(data=request.DATA)

        if backend == 'auth':
            if serializer.is_valid():
                token, created = Token.objects.get_or_create(user=serializer.object['user'])
                return Response({'token': token.key})
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

        else:
            # Here we call PSA to authenticate like we would if we used PSA on server side.
            user = register_by_access_token(request, backend)

            # If user is active we get or create the REST token and send it back with user data
            if user and user.is_active:
                token, created = Token.objects.get_or_create(user=user)
                return Response({'id': user.id , 'name': user.username, 'userRole': 'user','token': token.key})

@strategy()
def register_by_access_token(request, backend):
    backend = request.strategy.backend
    user = request.user
    user = backend._do_auth(
        access_token=request.GET.get('access_token'),
        user=user.is_authenticated() and user or None
    )
    return user

And finally I have these routes in urls.py:

...
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
url(r'^api-token-auth/', 'rest_framework.authtoken.views.obtain_auth_token'),
url(r'^api-token/login/(?P<backend>[^/]+)/$', views.ObtainAuthToken.as_view()),
url(r'^register/(?P<backend>[^/]+)/', views.register_by_access_token),
...

Everytime when I try to do auth, OAuth.io is working and the rqest to api returns

detail: "Invalid token"

I think that I missed something in the configuration of python-social-auth or I am doing everything wrong. So I will be glad if anyone has some ideas and want to help :)
