API-The bridge of any application

How does API works?

 API (Application Programming Interface) acts as a messenger between two systems, enabling them to
communicate.
 A client (app, website, device) sends a request to the API.
 The request is sent in a specific format (e.g., JSON, XML) to a server.
 The server processes the request, interacts with its database or service, and prepares a response.
 The API sends the response back to the client in a standard format.
 The client displays or uses the returned data (e.g., showing weather info, processing a payment)
 APIs can be public, private, or partner based on access control.
