Application Programming Interface. JavaScript Object Notation (JSON) |
An API (Application Programming Interface) is a set of protocols, routines, and tools for building software applications. It specifies how software components should interact and makes it easier for developers to create software by providing pre-built building blocks. APIs can be used to access data or functionality from other software applications or services. They can be used to integrate different software systems, enable communication between different applications, and simplify app development. APIs can vary depending on the type of programming language involved. For example, an API for a procedural language such as Lua could consist primarily of basic routines to execute code, manipulate data or handle errors while an API for an object-oriented language, such as Java, would provide a specification of classes and its class methods.
Client devices send a request in the form of an HTTP request, and are met with a response message usually in JavaScript Object Notation (JSON) or Extensible Markup Language (XML) format. Developers typically use Web APIs to query a server for a specific set of data from that server.
JSON (JavaScript Object Notation) is a lightweight format for storing and transporting data.
It is a standard text-based format for representing structured data based on JavaScript object syntax. JSON is often used when data is sent from a server to a web page, and it is a human-readable data interchange format developers use to store and transfer data. JSON is language-independent, which means it doesn't require a specific programming language. JSON objects are made up of key-value pairs where the keys must be a string, and the values can be any of the supported data types. JSON syntax is text-based and it supports data types such as objects, arrays, strings, and numbers.
