What is REST API?

REST API (Representational State Transfer Application Programming Interface) is a set of rules that allows different software applications to communicate over the internet. 

It uses standard web protocols like HTTP to request and exchange data between a client (e.g., a mobile app) and a server (e.g., a database). 

REST APIs are lightweight and scalable, making them ideal for SaaS startups or indie hackers to integrate services efficiently.

Why is it Important?

REST APIs are important for building user-friendly, connected, and seamless software products while saving time and resources.
