Secure Google API with Supabase + Edge Function

In this hands-on course, you'll master professional techniques to safeguard your applications by hiding sensitive API keys using Supabase Edge Functions. Designed for Flutter and full-stack developers, this training solves a critical real-world problem: how to securely integrate third-party APIs like Google Maps, Stripe, or OpenAI without exposing credentials in client-side code.

You'll learn to:

• Build production-ready API proxies that act as secure middlemen between your app and external services

• Implement robust security measures including CORS policies, rate limiting, and request validation

• Cache API responses to improve performance and reduce costs

• Handle authentication properly when your proxy needs user-specific access

• Deploy and monitor your proxy functions in a Supabase environment

• Integrate these solutions seamlessly with Flutter applications

Through practical examples, you'll transform from copying API keys directly into apps to implementing enterprise-grade security patterns. We'll cover common pitfalls, debugging techniques, and optimization strategies used by senior developers.

By course end, you'll be able to confidently protect any app from API key leaks while maintaining full functionality – a must-have skill in today's security-conscious development landscape.

Small mistakes as exposing your API key in the client side ,might lead to usage abuse by any person who can get the API key through reverse engineering, using the Edge function will end this danger.
