Yes
That is the OAuth Authorization Code Flow (User Access Tokens) yes?
You must first redirect the user to Twitch as per step 1.
Send the user you want to authenticate to your registered redirect URI. Then, an authorization page will ask the user to sign up or log into Twitch and allow the user to choose whether to authorize your application/identity system. Use this request:
redirect to https://api.twitch.tv/kraken/oauth2/authorize
?client_id=
&redirect_uri=
&response_type=code
&scope=
Then you do step 2 to exchange the returned Query String code for a oAuth token
