Overview
The Twitch API lets you access live stream data, game information, user profiles, and channel statistics from one of the world's largest game streaming platforms. Authentication uses OAuth 2.0 with either an App Access Token for public data or a User Access Token for viewer-specific features. It is a popular choice for building stream overlays, leaderboards, and Twitch-integrated apps.
Beginner Tip
Use the Client Credentials flow (POST to id.twitch.tv/oauth2/token with grant_type=client_credentials) to get an App Access Token — this is the quickest way to start reading public stream and game data without a user login.
