Welcome to Part 20 of the MongoDB Firebase Cloud Functions Training series! In this final CRUD-focused session, you’ll implement Update and Delete API routes using Firebase Cloud Functions and MongoDB. By the end of this video, you’ll have a fully functional, secure backend that allows authenticated users to modify or remove data from your collections.

With token validation, error handling, and clean code separation, your app will be production-ready for managing dynamic user data.
