 What is an API  An API (Application Programming Interface) is a set of protocols and tools that allows different software applications to communicate with each other, enabling them to exchange data and functionality seamlessly. Scenario API as a messenger that takes requests and tells a system what you want to do, and then returns the response back to you. It's like a waiter in a restaurant. You tell the waiter (API) what you want (your request), and the waiter takes your request to the kitchen (the system), and then brings you back what you asked for (the response). So, an API essentially allows different applications to talk to each other and work together, just like a waiter helps you communicate your order to the kitchen and brings you your food.
