What is an API?

An API (Application Programming Interface) is a collection of protocols and rules that allow software applications to communicate with one another, which enables sharing data as well as commanding them. There are several types of APIs, such as web APIs that communicate over the Internet using HTTP requests (REST and GraphQL for example), library API which access to functions in a programming libraries (e.g. NumPy, TensorFlow) or an operating system API where one application talks with the core of OS. They uncover URIs or endpoints which clients will hit HTTP, where messages can be formatted in anything (JSON, XML) Authentication: since APIs are an important resource, it is necessary to identify when and how each part of the system will access them securely so that its version can evolve compatible; Applications with APIs

What and why API Testing is needed?

API testing is the validation and evaluation of developed APIs, their architecture documentation as well as performance by making requests to its end points with certain expected output, errors at every areas/condition entrants that can be encountered during day-to-day working. It is necessary for both functionality testing — to verify that the API performs its intended purposes without any glitch and performance testing, which allows assessing response times under various loads. API testing also exposes vulnerabilities and makes implementations safer from undesired manipulations, confirms integration with other services so that data can be properly serviced between them and tests exception management to give proper info on invalid requests. It even helps to play a significant role in regression testing for making it dependable after updates and also validate the documentation which does not belongs misleading information w.r.t Api functionality.
