REST API

noun · also: api, json, webhook

What is rest api?

A REST API exposes resources at URLs and uses HTTP verbs (GET, POST, PUT, DELETE) to read and modify them. The most common modern API style.

Definition

Full definition of rest api

REST stands for Representational State Transfer. In practice it means: GET /users/123 to fetch a user, POST /users to create one, PUT /users/123 to update, DELETE /users/123 to remove. The structure is conventional, not enforced — some "REST" APIs bend the rules. Most no-code platforms (Tiny Command included) wrap REST APIs into typed actions so you don't hand-craft URLs.
