Explanation:
An application programming interface (API) is the code the CPU recognizes to perform a procedure in an application. API allows an application to communicate with another application, or an operating system, database, network, etc.
An Application Programming Interface (API) creates a consideration for a problem and specifies how clients should interact with software components that implement a solution to that problem.
More recently, API has been used to refer to a specific type of interface between a client and a server, which has been described as a “contract” between both - such that if the client makes a request in a specific format, it will always get a response in a specific format or initiate a defined action.This is a specialized form of API, defined as a Web API.
