Hi Niteesh,

I’m happy to help you with your question.

What is API?
It stands for Application Programming Interface and serves as a bridge to connect between software systems for communication.

Imagine ordering food through a mobile app. The app uses an API to send your order details to the restaurant's system. Then, the restaurant's system employs another API to send confirmation and delivery updates back to the app.

In a similar scenario, the food delivery app tracks delivery agent's location using a Map API (provides by Google Maps).

In the trading context, APIs enable you to automate trading/investing based on predefined rules. And also it is used for obtaining live market data such as prices, volumes, and market depth and placing, modifying, canceling orders and many more. Please visit FYERS API page:
