OAuth Integration Tutorial

OAuth is a widely used protocol for authorization. This guide will walk you through integrating OAuth into your application.

1. OAuth Overview

OAuth 2.0 is the most common version for modern applications. It allows users to grant access to their resources without sharing credentials.

Key Concepts

• Authorization Server: Issues access tokens
• Resource Server: Protects APIs with token validation
• Client Application: Requests access on behalf of the user

2. Implementation Steps

1. Register Your Application

   • Go to OAuth Configuration Guide to set up client credentials
   • Use the client_id and client_secret for authentication

2. Redirect to Authorization Endpoint

   GET https://auth.example.com/authorize?response_type=code&client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI
   

   📌 Replace YOUR_CLIENT_ID and YOUR_REDIRECT_URI with actual values

3. Handle Redirect and Exchange Code

   • Use the authorization code to request an access token:

   POST https://auth.example.com/token
   

   • Include parameters: grant_type=authorization_code, code=CODE, redirect_uri=REDIRECT_URI

3. Security Best Practices

🔐 Always use HTTPS for token transmission
🔄 Implement token refresh mechanisms
🛡️ Store client_secret securely (never in client-side code)
