How to revoke a OAuth Token? [C#]

Don’t send it as a “CancellationToken”

Also you don’t have to post screenshots

Just do four spaces and your code

like this

So

await httpclient.PostAsync("https://id.twitch.tv/oauth2/revoke?client_id=" + client_id + "&token=" + token);

The cancellationToken is nothing to do with oAuth revocation it’s for C# to receive a notification of a cancellation of the request.
