What is an API? An API, or applicationprogramminginterface, is a set of rules or protocols that enables software applications to communicate with each other to exchange data, features and functionality.
APIs, or Application Programming Interfaces, are the invisible backbone of modern software development. They enable different applications, platforms, or systems to communicate and exchange data seamlessly, powering everything from your weather app to your favorite e-commerce checkout.
In contrast to a user interface, which connects a computer to a person, an applicationprogramminginterface connects computers or pieces of software to each other.
APIs, or applicationprogramminginterfaces, are sets of instructions that let applications communicate with each other. Learn more in our Beginner's Guide to APIs.
In technical terms, an API is a set of rules and tools that lets one application request data or services from another. For example, when you use a weather app to check the forecast, the app uses an API to fetch the latest weather data from a server. Why Are APIs Important?
An API (Application Programming Interface) is a set of features and rules that exist inside a software program (the application) enabling interaction with it through software - as opposed to a human user interface.
In this guide, learn what an API is, how it works, and the common types of APIs used today, with real-life examples. API stands for “Application Programming Interface.” It allows two or more applications to communicate with one another through a predefined set of rules.
What is an API (ApplicationProgrammingInterface)? What is an API? APIs are mechanisms that enable two software components to communicate with each other using a set of definitions and protocols. For example, the weather bureau’s software system contains daily weather data.
An API (applicationprogramminginterface) is a set of rules laying out how one piece of software can communicate with another. I've probably used an API dozens of times today, without even realizing it.
APIs let your product or service communicate with other products and services without having to know how they’re implemented. This can simplify app development, saving time and money.
