What is API?
Application Programming Interface (API) is a software intermediary for creating and integrating application software that allows two applications to exchange data. APIs conform to REST and HTTP standards, are easy to use and are developer-friendly. The APIs are well documented for use and version control. The API has its software development lifecycle (SDLC), which includes designing, testing, building, managing, and versioning, just like any other software produced.
What is JSON API?
JSON API is a text-based data exchange format designed to work with HTTP. The JSON API defines how clients should request data from the server and how the server should respond to requests. The JSON API provides improved caching functionality and optimizes HTTP requests by eliminating unnecessary server requests. JSON API is described at JSONAPI.org and differs from REST API.
