# Twitch

> Control a Twitch channel and react to channel events — update title and category, run commercials, manage polls and predictions, post chat, and trigger rules on follows, subs, cheers, and raids.

The **Twitch** device controls a [Twitch](https://www.twitch.tv/) channel and reacts to its live channel events, so your automations can respond to what happens on stream.

## Connection

Each device controls one broadcaster channel and authenticates with a Twitch application you register in the [Twitch Developer Console](https://dev.twitch.tv/docs/authentication/register-app/). Provide the **broadcaster login** (your channel name), the application's **client ID** and **client secret**, and a user **refresh token** for the channel. See the [Twitch developer documentation](https://dev.twitch.tv/docs/) for creating an application and obtaining a token.

## Commands

The Twitch device supports channel, chat, and engagement operations, including:

* Update the stream **title** or **category**
* Create a stream **marker**, run a **commercial** break, or capture a **clip**
* Start or cancel a **raid** to another channel
* Post a **chat message** or a highlighted **announcement**
* Create and end a **poll**
* Create, lock, resolve, or cancel a **prediction**

## State and triggers

The device reports its connection state and raises triggers your [rules](/automation/rules) can react to, including:

* The channel going **live** or **offline**
* The **title or category** changing
* A new **follower** or **subscriber**, and **gifted** subscriptions
* A viewer **cheering with Bits**
* Another channel **raiding** yours
* A **channel-point reward** being redeemed

Trigger data such as the viewer name, subscription tier, Bits amount, and reward title is available for use in rule actions.
