StreamLinked - API, Auth, EventSub and IRC for Twitch

"This is the best asset library for integrating with Twitch in Unity."

Do you need Twitch integration into Unity?

Need to call Twitch's API?

Need something to handle authentication tokens and OAuth?

Do you want to subscribe to Twitch Events?

Or do you need to read Twitch chat messages via an IRC across one or more channels?

This is the complete solution for you!

This package brings down Twitch's API documentation and implements it into Unity C#, from API references, EventSub subscriptions, IRC notifications. If Twitch mentions it in their documentation you will be able to access it in C# in your project.

Whether its:

✔️A Authentication Token

✔️A API Reference

✔️A EventSub Reference

✔️A IRC Tag Reference

StreamLinked has been created to match the documentation on Twitchs API website as close as possible to make request references as easy as possible and to handle what you need to connect to and request information from Twitch for your coded projects.

Authentication

The process has never been easier, provide your Client ID and/or Secret, choose your authentication method and the API Client will automatically get you a token. Done automatically, done in stages or it can be done manually if need be. The framework is there for your solution.

Need just one token? need many tokens? All tokens are handled independently of each other so you can make as many tokens as you need and use them when you want to.

Twitch API

All the endpoints, available from a single task or coroutine, producing an object with all the information inside. Its never been easier to call Twitchs API.

Each API call, listed, assigned and allocated a class to make any request as simple as one method call to Twitch API.

Dont want to wait till play mode? The Twitch API Client can make calls to the API from the Editor. Perfect for testing your tokens or messaging Twitch during development or browsing possible endpoints for what you need next.

And even if you dont wish to use the additional solutions provided, everything Twitch goes through its API references so you can create whatever you want.

EventSub

WebSocket setup, API Subscriptions. Set up to receive any notification Twitch provides. All accessible with provided UnityEvents.

Each EventSub subscription has its own class returned to you in an easy to read format, perfect to get the exact information you need.

Twitch IRC

Connect to Twitch chat rooms and receive user messages.

All processed into a convenient object and supports Twitch's tag commands returned.

On top of that, it includes a Badge and Emote downloader and manager, all processed to display in TextMeshPro!

Twitch chat messages in Unity just like it is online, you couldnt ask for anything else.
