Question: What Is An API Simple Explanation?

What is an API and how does it work?

API stands for Application Programming Interface.

An API is a software intermediary that allows two applications to talk to each other.

In other words, an API is the messenger that delivers your request to the provider that you’re requesting it from and then delivers the response back to you.

What is an API with example?

API is the way for an application to interact with certain system/application/library/etc. For example, there are API’s for OS (WinAPI), API’s for other applications (like databases) and for specific libraries (for example, image processing), etc. APIs are usually developed in a form consumable by a client application.

How do you define API?

In computer programming, an application programming interface (API) is a set of subroutine definitions, communication protocols, and tools for building software. In general terms, it is a set of clearly defined methods of communication among various components.

What is Web API in layman’s terms?

What is Web API? To put it in simple terms, API is some kind of interface which has a set of functions that allow programmers to access specific features or data of an application, operating system or other services. Web API as the name suggests, is an API over the web which can be accessed using HTTP protocol.

Why is API used?

An application program interface (API) is a set of routines, protocols, and tools for building software applications. Basically, an API specifies how software components should interact. Additionally, APIs are used when programming graphical user interface (GUI) components.

What exactly is an API?

Application Programming Interface (API)

In basic terms, APIs just allow applications to communicate with one another. When people speak of “an API”, they sometimes generalize and actually mean “a publicly available web-based API that returns data, likely in JSON or XML”. An API is not a database.

What are types of API?

The following are the most common types of web service APIs: SOAP (Simple Object Access Protocol): This is a protocol that uses XML as a format to transfer data.

Apart from the main web APIs, there are also web service APIs:

  • SOAP.
  • XML-RPC.
  • JSON-RPC.
  • REST.

What is difference between API and Web services?

The only difference is that a Web service facilitates interaction between two machines over a network. An API acts as an interface between two different applications so that they can communicate with each other. Web service also uses SOAP, REST, and XML-RPC as a means of communication.

What is REST API example?

A REST API defines a set of functions which developers can perform requests and receive responses via HTTP protocol such as GET and POST. The World Wide Web (WWW) is an example of a distributed system that uses REST protocol architecture to provide a hypermedia driven interface for websites.
