Invalid Authorization Token

Well I send it to a different redirectURI because I want to do something different once I get the access token. Once I get the access token I want to get the person who authenticateds’ username so I can make a webhook to subscribe to the event of them broadcasting, so I want different code to run than in the /twitch_authorized/ route. I’ve got more code but it’s all commented out because I can’t do anything with the invalid token. Could I have just saturated my personal tokens or something so the new ones aren’t valid?
