Application Programming Interface (API) in a nutshell

Web service APIs

Web service APIs send and receive messages across the web using HTTP to transport the request and response. Web service APIs are not language-specific.

Native library APIs

Native library APIs involve incorporating code directly into the project for desired functionality (e.g., navigation, payment, email communication, etc.). Native library APIs are language-specific.

How regular browser request is different from APIs?

The data you get when you browse something on the internet is a combination of HTML, CSS, and JavaScript. Here the purpose is a machine to human communication.

An example for real-life application of API

Let’s take the example of Uber. As shown below the Uber controls the user experience and relies on third-party services for infrastructure, communication, navigation, and payments. These service providers are providing their services through APIs and integrated into Uber. Hence, Uber doesn’t want to develop everything from scratch.
