API stands for Application Programming Interface. It is a way that allows two different software applications to communicate and exchange data with each other.
To understand API easily, imagine a restaurant. A customer gives an order to the waiter, and the waiter takes the order to the kitchen. After the food is prepared, the waiter brings it back to the customer. In this example, the waiter works like an API because it connects the customer and the kitchen.
In web development, an API usually connects the frontend and backend. For example, when we open an online shopping website and view products, the frontend sends a request to the backend through an API. The backend processes the request, gets the required information from the database, and sends the response back through the API.
APIs commonly use HTTP methods such as GET, POST, PUT, and DELETE. GET is used to retrieve data, POST is used to create data, PUT is used to update data, and DELETE is used to remove data.
APIs often exchange data in JSON format, which is easy for applications to understand.
In modern applications, APIs are used everywhere, including websites, mobile applications, payment systems, weather applications, and social media platforms.
In simple words, an API acts as a bridge that allows different software systems to communicate with each other.
