I’m trying to build an app similar to this https://codepen.io/freeCodeCamp/full/Myvqmo (you can’t see online and offline channels, because API rules changed and every app similar to this don’t work).
So, I use an ajax-request and add a client-id
But despite of that, I get a 404 mistake. According to these rules, you need an “Authorization” in the “headers”, but I can’t understand where I should get this authorization key.
So could you please help me to create a proper ajax-request?
