We live in a world where everything is connected and data is shared. APIs are the gateway to connect systems so that they can share data with each other. In this article, we’ll take a look at what APIs are, what they do, and how you can use them on your own projects.
Service providers use APIs to expose their capabilities to a broad ecosystem of partners and developers. An API makes it easier for other programmers to interact with companies.
What is an API?
An API is an interface that allows two pieces of software to communicate with each other. It is a set of rules that govern how data is exchanged between the two systems. An API can be considered a contract between the two systems, specifying how data will be exchanged.

Is API a product or a service?
API stands for Application Programming Interface. It is a set of rules and protocols that allow software components to communicate with each other. APIs are used when programming graphical user interfaces (GUI) components, such as buttons and menus. They are also used when programming applications that work with databases or web services.
There are two types of APIs: SOAP and REST. SOAP (Simple Object Access Protocol) is a protocol that uses XML (Extensible Markup Language) for message exchange. REST (Representational State Transfer) is a simpler style of communication that uses HTTP (Hypertext Transfer Protocol) for message exchange.
An API can be either a product or a service. If it is a product, it is usually provided as a software library that can be used by developers to create their own applications. If it is a service, it is usually provided as a web service that applications over the Internet can access.
Who uses APIs?
In the context of web applications, an API typically refers to a set of standards-based rules and specifications that define how one application can request data from another application.
There are two types of APIs: public and private. Public APIs are generally available to anyone who wants to use them, while private APIs are only accessible to authorized users.
API use has become more commonplace as the internet has become more interconnected. Many web-based applications rely on APIs to function properly. For example, when you book a hotel room online, the booking website likely uses an API to interact with the hotel’s reservation system. Similarly, when you order a product from an online store, the checkout process likely involves several different APIs (e.g., for payment processing, shipping, etc.).

Conclusion
API is a service that enables applications to communicate with each other. It is a set of rules and protocols that allow software programs to interact with each other. API is not a product, but it is an important component of many products.
