What is Web API?

A Web API (also known as a Web Service API) is an application programming interface (API) for either a web server or a web browser. It is a framework that allows different software systems to communicate and exchange data over the internet, typically using HTTP. Web APIs are commonly used to provide access to data and functionality from web applications, mobile apps, and other connected devices. They often follow RESTful principles, using standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources.
