What is API: The term “API” stands for Application Programming Interface. If you break that down word by word, you can get a pretty good sense of what it means. An API is an interface or middleware that can be used to program software that interacts with an existing application. In practice, an API is “a set of functions and procedures” that allow you to access and build upon the data and functionality of an existing application.
Nowadays, when we’re talking about APIs we’re typically referring to web APIs, which expose an application’s data and functionality over the internet. If you look closely, you’ll see that web APIs power our everyday lives:
-When you log into a website using your Facebook profile
-When you switch on Netflix and see dozens of new movies flood the screen
-When you look for flights on Google
Technically, Web APIs usually send data back and forth using HTTP requests. These requests often return textual data in the form of a JSON or XML response.
What is API testing: API TESTING is a software testing type that validates Application Programming Interfaces (APIs). The purpose of API Testing is to check the functionality, reliability, performance, and security of the programming interfaces.
