Django REST Framework (DRF) Integration for Oauth2 authentication

Easily integrate multiple Providers Login into your Django REST Framework project using Omni-Authify. This guide will walk you through configuration, setting up API views, updating URLs, and best practices.

⚙️ Configure Settings

Add the Omni-Authify settings to your Django project settings to include Facebook, GitHub, Google and/or any other OAuth providers.

import os
from dotenv import load_dotenv

load_dotenv()

OMNI_AUTHIFY = {
    'PROVIDERS': {
        'facebook': {
            'client_id': os.getenv('FACEBOOK_CLIENT_ID'),
            'client_secret': os.getenv('FACEBOOK_CLIENT_SECRET'),
            'redirect_uri': os.getenv('FACEBOOK_REDIRECT_URI'),
            'state': os.getenv('FACEBOOK_STATE'), # optional
            'scope': os.getenv('FACEBOOK_SCOPE'), # by default | add other FB app permissions you have!
            'fields': os.getenv('FACEBOOK_FIELDS'),
        },
        'github':{
            'client_id':os.getenv('GITHUB_CLIENT_ID'),
            'client_secret':os.getenv('GITHUB_CLIENT_SECRET'),
            'redirect_uri':os.getenv('GITHUB_REDIRECT_URI'),
            'state': os.getenv('GITHUB_STATE'),
            'scope':os.getenv('GITHUB_SCOPE'),
        },
        'google': {
            'client_id': os.getenv('GOOGLE_CLIENT_ID'),
            'client_secret': os.getenv('GOOGLE_CLIENT_SECRET'),
            'redirect_uri': os.getenv('GOOGLE_REDIRECT_URI'),
            'state': os.getenv('GOOGLE_STATE'), # optional
            'scope': os.getenv('GOOGLE_SCOPES'),
        },
        'linkedin': {
            'client_id': os.getenv('LINKEDIN_CLIENT_ID'),
            'client_secret': os.getenv('LINKEDIN_CLIENT_SECRET'),
            'redirect_uri': os.getenv('LINKEDIN_REDIRECT_URI'),
            'scope': os.getenv('LINKEDIN_SCOPE'),
        },
                
        # Add other providers here if needed
        'telegram': {
            # Coming....
        }
    }
}

DRF API Views

Learn how to create API views to handle multiple Providers login and callback in your Django REST Framework application.

📝 Prerequisites

• Installation: Install Omni-Authify with Django REST Framework support using the following command:

  pip install omni-authify[drf]
• Django 2.2 or higher

• Django REST Framework installed

• Omni-Authify installed and configured (see Installation Guide)

🚀 Setting Up API Views

Create API views to handle the login and callback processes.

views.py

This version uses the OmniAuthifyDRF helper class for an easier implementation.

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status

from omni_authify.frameworks.drf import OmniAuthifyDRF

# ======== Facebook Login ========

🌐 Update URLs

Add the login and callback views to your app's urls.py file:

# urls.py

from django.urls import path
from .views import (
    FacebookLoginAPIView, FacebookCallbackAPIView,
    GitHubLoginAPIView, GitHubCallbackAPIView,
    GoogleLoginAPIView, GoogleCallbackAPIView,
    LinkedInLoginAPIView, LinkedInCallbackAPIView,
)

urlpatterns = [
    # ======== Facebook Login ========
    path('facebook/login/', FacebookLoginAPIView.as_view(), name='facebook_login'),
    path('facebook/callback/', FacebookCallbackAPIView.as_view(), name='facebook_callback'),
  
    # ======== GitHub Login ========
    path('github/login/', GitHubLoginAPIView.as_view(), name='github_login'),
    path('github/callback/', GitHubCallbackAPIView.as_view(), name='github_callback'),

    # ======== Google Login ========
    path('google/login/', GoogleLoginAPIView.as_view(), name='google_login'),
    path('google/callback/', GoogleCallbackAPIView.as_view(), name='google_callback'),
  
    # ======== LinkedIn Login ========
    path('linkedin/login/', LinkedInLoginAPIView.as_view(), name='linkedin_login'),
    path('linkedin/callback/', LinkedInCallbackAPIView.as_view(), name='linkedin_callback'),
  
]

✅ Best Practices

• 🔒 Use Environment Variables: Always use environment variables to store important information like client_id and client_secret. This helps keep your credentials safe 🛡️.

• 🔗 Match Redirect URI: Make sure the redirect_uri is consistent between your Provider App settings and your code to avoid errors 🚫.
