uh okay i found the answer by myself "When creating this app, you will need to enter your redirect URI, which is where users are redirected after being authorized. " … but the thing i want to do is not a webpage or a web application, it’s just take information about my activity on twitch, in order to program a raspbery pi and then turn on some lights in my room (for example when someone follow me the raspberry turn on a alarm light for the show) and display on my tv screen the username of the follower, so i need to create a webpage just for something is not on the web ?
thanks a lot
