Fullstack Food Delivery Web Development Training – API Endpoint Token Validation

🔥 In Part 20 of the Fullstack Food Delivery Web Development series, we implement token validation for API endpoints, ensuring that only authenticated users can access protected Firebase Cloud Functions.

✅ What you’ll learn in this video:
✔️ Creating secure API endpoints using Firebase Cloud Functions
✔️ Extracting the Firebase Auth token from Authorization headers
✔️ Validating tokens using firebase-admin.auth().verifyIdToken()
✔️ Returning user-specific data only after successful verification
✔️ Building a token-protected getUserData or createOrder endpoint
✔️ Handling invalid/missing token errors with appropriate status codes
✔️ Integrating secure API calls in your React frontend with fetch()
✔️ Testing API routes with tools like Postman or curl

💡 Why Token Validation on API Endpoints Is Essential:
🔹 Secures backend APIs against unauthorized access
🔹 Protects sensitive operations (e.g., payments, user data)
🔹 Maintains trust by keeping user sessions secure
🔹 Supports role-based access control in your app
