REST API

Category: Infrastructure

“REST A-P-I”

A common, predictable way for programs to ask each other for information or to make a change, using plain web addresses.

Lesson #8: The Builder's Toolkit: Hooks, Plugins, APIs & SDKs →
Think of it like…

A restaurant menu with numbered items. Everyone orders the same way, so the kitchen always understands.

Everyday example

A weather widget on your desktop asks a weather service for today's forecast and gets it back in seconds.

Construction example

The job-costing app asks the supplier's REST API for current lumber prices before printing an estimate.

Business example

A dashboard pulls yesterday's sales from the accounting system through its REST API every morning.

Why this matters

Most business software talks through REST, so knowing the term tells you whether two tools can connect at all.

One-sentence summary

A REST API is the standard, web-address way that two programs exchange data.

Try it yourself

Check whether two tools you use both advertise an API. If yes, they can likely be connected.
