Getting starting with twitch app

[BarryCarlyon]

@Davide_Vacca

Once created a twitch app in my console i need to know what is the OAuth redirection URL

The oAuth URL is the URL that users are redirected to, to complete steps 2/3/4 of the regular user oAuth flow.

As already covered in your original post

Need help about twitch.tv application

That would be the URL/website you redirect the user to, to complete step 3 of regular user oAuth Exchanging a code for an access (and refresh) tokens. And thus the website that will talk to your key storage to store the keys for your bot to use. This API references how to use the subscribers endpoint
