I can't get the authentication token for the API

API
5

I got the access token, but what do I do with it, do I need to validate it?

My Code:

headers:
{ 
					"Client-ID": 'twitchClientID' ,
  "Authorization": 'Bearer tokentwitch' 
    } };

Error:

{"error":"Unauthorized","status":401,"message":"Invalid OAuth token"}
