Twitter Bot for Auto-Favoriting and Retweeting Tweets

The Twitter bot, written with Google Apps Script, will auto-favorite and retweet tweets every few minutes. Do include the Twitter API library in your Google Scripts project as discussed in the previous tutorial on creating Twitter bots.

// Fill the Twitter Keys and then choose Run -> Start Bot

TWITTER_CONSUMER_KEY = '123';
TWITTER_CONSUMER_SECRET = '123';
TWITTER_ACCESS_TOKEN = '123';
TWITTER_ACCESS_SECRET = '123';
TWITTER_SEARCH_PHRASE = 'filter:links labnol.org';

function Start_Bot() {
  var props = PropertiesService.getScriptProperties();

  props.setProperties({
    TWITTER_CONSUMER_KEY: TWITTER_CONSUMER_KEY,
    TWITTER_CONSUMER_SECRET: TWITTER_CONSUMER_SECRET,
    TWITTER_ACCESS_TOKEN: TWITTER_ACCESS_TOKEN,
    TWITTER_ACCESS_SECRET: TWITTER_ACCESS_SECRET,
    SINCE_TWITTER_ID: 0,
  });

  var twit = new Twitter.OAuth(props);

  // Test Twitter authorization

  if (!twit.favorite('628053456071192576')) {
    throw new Error('Please check your Twitter access tokens');
    return;
  }

  ScriptApp.newTrigger('labnol_twitterBot').timeBased().everyMinutes(10).create();
}

function labnol_twitterBot() {
  try {
    var props = PropertiesService.getScriptProperties(),
      twit = new Twitter.OAuth(props);

    if (twit.hasAccess()) {
      var tweets = twit.fetchTweets(
        TWITTER_SEARCH_PHRASE,
        function (tweet) {
          // Skip tweets that contain sensitive content
          if (!tweet.possibly_sensitive) {
            return tweet.id_str;
          }
        },
        {
          multi: true,
          lang: 'en', // Process only English tweets
          count: 5, // Process 5 tweets in a batch
          since_id: props.getProperty('SINCE_TWITTER_ID'),
        }
      );

      if (tweets) {
        props.setProperty('SINCE_TWITTER_ID', tweets[0]);

        for (var i = tweets.length - 1; i >= 0; i--) {
          twit.retweet(tweets[i]);
          twit.favorite(tweets[i]);

          /* Wait between 10 seconds and 1 minute */
          Utilities.sleep(Math.floor(Math.random() * 50000) + 10000);
        }
      }
    }
  } catch (f) {
    Logger.log('Error: ' + f.toString());
  }
}
