I am building an interactive video project. Currently it allows people to tweet commands at it and the video and audio will respond to commands. I want to see how Twitch can enhance this experience but I dont know which technology to focus on.

I would like the idea of allowing people in chat to type commands and to be able to count the amount of people doing so. That might be a chatbot. Does that send a JSON that i could access over an http?

Is there a different way i could achieve my goal?

Thanks in advance.

Chat is an implementation of IRC over IRC or WS, not JSON payloads over HTTP.

# How to start

Starting with Twitch beings with the docs

> **[Home](https://dev.twitch.tv/docs)**

> Live Streaming, Meet Developers.

And you need a ClientID

[https://dev.twitch.tv/docs/authentication/#registration](https://dev.twitch.tv/docs/authentication/#registration)

To do anything you need to be able to tell Twitch who you are and/or which user you are on behalf making requests for, thats authentication, which for Twitch is oAuth

> **[Getting OAuth Access Tokens](https://dev.twitch.tv/docs/authentication/getting-tokens-oauth/)**

If you then want to go ChatBot. it’s “basically” IRCv3 which is documented here:

> **[Chat & Chatbots](https://dev.twitch.tv/docs/chat)**
>
> Twitch Chat & Chatbots

If you wanted to go Extensions then, what you describe is similar to the Color Changing Hello World Example. Extensions are documented here.
