gRPC APIs are a type of API that uses Google's open-source gRPC framework to enable fast, efficient communication between services — commonly used in microservices architectures.

Instead of the traditional REST approach (JSON over HTTP), gRPC uses Protocol Buffers (a compact binary format) over HTTP/2, making it significantly faster and more efficient, especially for high-performance or real-time applications. 

In this session, we will go over the basics of testing gRPC APIs with Postman.
