I gave you the oAuth dance here
This website uses it’s own clientID and secret to create a token. You cannot use it, using YOUR clientID
As you must write the code to exchange the code for a token (when using OAuth Authorization Code Flow
as documented
If using implict make sure you set the right data when passing to /authorize
Again Discord is giving you a bot login token for running a bot, it’s not really a oAuth token
oAuth for implicit is noted here
If you don’t plan to use oAuth in your App, set it to https://localhost
as it should say on the ClientID creator page
