How APIs Works
This page explains how APIs works without assuming a technical background.
The core idea
An API is a defined interface that lets one system interact with another. It tells software what requests are allowed and what kind of response to expect.
In simple terms, APIs help programs talk to each other.
A system sends a request using the API rules, and another system returns data, confirms an action, or reports an error.
APIs may be used inside companies, between cloud services, in mobile apps, on websites, or across business platforms.
How it works step by step

APIs may be used inside companies, between cloud services, in mobile apps, on websites, or across business platforms.
APIs matter because modern software is deeply connected. Payment systems, maps, weather data, login systems, cloud tools, and AI services often rely on APIs.
Understanding APIs helps people understand how different software products fit together.

A common misconception is that APIs are only for developers. In reality, APIs shape many digital experiences normal users rely on every day.
Another misconception is that all APIs are public. Many APIs are private, internal, or restricted.
