How to obtain an Client-ID

There are many ways on obtaining it, the main one is by opening the developer tools on a twitch stream and capturing it from the headers of gql.twitch.tv requests, also you can try on registering an app on https://dev.twitch.tv

An example of a valid client ID for Twitch is: jknof83ly4odx7cthm5nv7xji6h2ek

How to obtain my OAuth token

As you may have guessed, you can obtain it too by opening developer tools on a twitch stream and capturing it from the Authorization header of gql.twitch.tv requests, it should look like "Authorization: OAuth fv34m44bdnvo1jkegobiuo9bx84" where "fv34m44bdnvo1jkegobiuo9bx84" is the token you should use on OAuth parameters of this script.

An example of an OAuth token is: fv34m44bdnvo1jkegobiuo9bx84
