OAuth social login integration in No-Code - Mini Project: Build & Apply

OAuth Social Login Integration

📖 Scenario: You are building a website that allows users to log in using their social media accounts like Google or Facebook. This makes it easier for users to sign in without creating a new password.

🎯 Goal: Build a simple OAuth social login integration setup that connects your website to a social login provider and allows users to authenticate using their social account.

📋 What You'll Learn

Create an OAuth client configuration with exact client ID and redirect URI

Set up the OAuth authorization URL with required parameters

Implement the logic to handle the OAuth redirect and extract the authorization code

Complete the OAuth flow by exchanging the authorization code for an access token

💡 Why This Matters

🌍 Real World

OAuth social login integration is widely used in websites and apps to allow users to sign in quickly using their existing social media accounts, improving user experience and security.

💼 Career

Understanding OAuth integration is essential for web developers, backend engineers, and security specialists working on authentication and user management systems.

1

Create OAuth Client Configuration

Create a dictionary called oauth_client with these exact entries: 'client_id': '1234567890-abcdefg.apps.googleusercontent.com' and 'redirect_uri': 'https://yourwebsite.com/oauth/callback'.

No-Code

# Create the OAuth client configuration dictionary
# Your code here

Need a hint?

Use a dictionary with keys client_id and redirect_uri exactly as shown.

2

Set Up OAuth Authorization URL

Create a string variable called auth_url that builds the OAuth authorization URL using oauth_client['client_id'] and oauth_client['redirect_uri']. The URL should be: https://accounts.google.com/o/oauth2/auth?client_id=1234567890-abcdefg.apps.googleusercontent.com&redirect_uri=https://yourwebsite.com/oauth/callback&response_type=code&scope=openid email profile.

No-Code

oauth_client = {
    'client_id': '1234567890-abcdefg.apps.googleusercontent.com',
    'redirect_uri': 'https://yourwebsite.com/oauth/callback'
}
# Create the OAuth authorization URL string
# Your code here

Need a hint?

Use an f-string to insert client_id and redirect_uri into the URL exactly as shown.

3

Handle OAuth Redirect and Extract Authorization Code

Create a function called handle_oauth_redirect that takes a parameter redirect_url. Inside the function, extract the value of the code parameter from redirect_url and assign it to a variable called auth_code.

No-Code

oauth_client = {
    'client_id': '1234567890-abcdefg.apps.googleusercontent.com',
    'redirect_uri': 'https://yourwebsite.com/oauth/callback'
}
auth_url = f"https://accounts.google.com/o/oauth2/auth?client_id={oauth_client['client_id']}&redirect_uri={oauth_client['redirect_uri']}&response_type=code&scope=openid email profile"

# Define the function to handle OAuth redirect and extract the code
# Your code here

Need a hint?

Use urllib.parse to parse the URL and extract the code parameter.

4

Exchange Authorization Code for Access Token

Create a function called exchange_code_for_token that takes a parameter auth_code. Inside the function, create a dictionary called token_request_data with these exact entries: 'code': auth_code, 'client_id': oauth_client['client_id'], 'redirect_uri': oauth_client['redirect_uri'], 'grant_type': 'authorization_code'. Then return token_request_data.

No-Code

oauth_client = {
    'client_id': '1234567890-abcdefg.apps.googleusercontent.com',
    'redirect_uri': 'https://yourwebsite.com/oauth/callback'
}
auth_url = f"https://accounts.google.com/o/oauth2/auth?client_id={oauth_client['client_id']}&redirect_uri={oauth_client['redirect_uri']}&response_type=code&scope=openid email profile"

def handle_oauth_redirect(redirect_url):
    from urllib.parse import urlparse, parse_qs
    parsed_url = urlparse(redirect_url)
    query_params = parse_qs(parsed_url.query)
    auth_code = query_params.get('code', [null])[0]
    return auth_code

# Define the function to exchange the authorization code for an access token
# Your code here

Need a hint?

Create a dictionary with the exact keys and values as shown, then return it.
