MongoDB Firebase Cloud Functions Training – POST Request: Create Data in MongoDB with Cloud Functions

Welcome to Part 18 of the MongoDB Firebase Cloud Functions Training series! In this session, you’ll build a fully functional POST API endpoint using Firebase Cloud Functions that securely stores data in MongoDB Atlas. This is your first end-to-end implementation that bridges your frontend or Postman client with a real-time database write!

You’ll validate requests, use authentication tokens, and insert cleanly structured documents into your MongoDB collections.

✅ What You’ll Learn in This Video:

✔️ Creating a POST HTTP Cloud Function endpoint
✔️ Parsing incoming request data and validating fields
✔️ Verifying the Firebase ID token from request headers
✔️ Connecting to MongoDB and inserting the payload into a specific collection
✔️ Returning a custom success/failure response to the client

💡 Why This Step Matters:

🔹 Powers your app’s ability to store new user-generated content
🔹 Enables secure, real-world interactions between frontend and backend
🔹 Forms the base for other actions like creating logs, feedback, or dynamic records
