Tweet using application in Twitter with Meteor

I am successful in authorizing a request with application-only authentication. But when I tried to post a tweet with REST API. The error is related to not having an access to post a tweet. So I do a research and found out that Twitter doesn't allow app-only authentication to post tweets.

"And it will not be able to: Post Tweets or other resources;"

But I found the "Your access token" area. Can I use it to post tweet? How can I use it?

Also can I use the same method for commenting?

Here is my code so far,

HTTP.call('POST', 'https://api.twitter.com/oauth2/token', {
            params: { 'grant_type':'client_credentials'},
            headers: {
                'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8',
                'Authorization': 'Basic '+base64token
            }
        },function (error, response) {
            if (!error && response.statusCode == 200) {
                token = response.data.access_token;
                HTTP.call('POST', 'https://api.twitter.com/1.1/statuses/update.json', {
                    params: { 'status':data.tweet},
                    headers: {
                        'Authorization': 'Bearer '+token
                    }
                },function (error, response) {
                    if (!error && response.statusCode == 200) {
                        console.log(response);
                    } else {
                        console.error(error.message);
                    }
                }); 
            } else {
                console.error(error.message);
            }
        });
