API (Application Programming Interface) is a set of all procedures and functions that allow us to create an application by accessing the data or features of another program. Testing of such procedures is known as API Testing. 

Web API - can be defined as something that takes the request from a client system to a web server and sends back the response from a web server to a client machine.
