Thank you. I am using a library for OAuth, so I completely overlooked it as I only browsed that section of docs.
Having never used a boolean in a url paramater, I just want to sanity check that the following should do.
GET 'https://id.twitch.tv/oauth2/authorize?force_verify=true&response_type=token&client_id=uo6dggojyb8d6soh92zknwmi5ej1q2&redirect_uri=http://localhost&scope=viewing_activity_read&state=c3ab8aa609ea11e793ae92361f002671'
