Post a tweet to my feed using Google Apps Script

Question

As the title suggests, my goal here is to be able to send a tweet from a script.gs. The tweet would be posted to my feed, ideally without me having to visit the Twitter website.

I wrote two main functions to attempt this:

script.gs

//post tweet
function oAuth() {
  var CONSUMER_KEY = "**********************";
  var CONSUMER_SECRET = "*************************************************";
  ScriptProperties.setProperty("TWITTER_CONSUMER_KEY", CONSUMER_KEY);
  ScriptProperties.setProperty("TWITTER_CONSUMER_SECRET", CONSUMER_SECRET);
  var oauthConfig = UrlFetchApp.addOAuthService("twitter");
  oauthConfig.setAccessTokenUrl("https://api.twitter.com/oauth/access_token");
  oauthConfig.setRequestTokenUrl("https://api.twitter.com/oauth/request_token");
  oauthConfig.setAuthorizationUrl("https://api.twitter.com/oauth/authorize");
  oauthConfig.setConsumerKey(ScriptProperties.getProperty("TWITTER_CONSUMER_KEY"));
  oauthConfig.setConsumerSecret(ScriptProperties.getProperty("TWITTER_CONSUMER_SECRET"));
  var options = {muteHttpExceptions: true,oAuthServiceName:'twitter',oAuthUseToken:'always'}
  var url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
  var response = UrlFetchApp.fetch(url, options).getContentText();
  Logger.log(response);
}
function postTweet() {
  oAuth();
  Logger.log('oAuth complete');
  var status = "Tweet";
  var Roptions = {
    method: "post",
    oAuthServiceName: "twitter",
    oAuthUseToken: "always",
    status: status
  };
  var url = "https://api.twitter.com/1.1/statuses/update.json";
  Logger.log('begin post');
  var request = UrlFetchApp.fetch(url, Roptions); //the trouble line. Execution stops.
  Logger.log('post complete');
}

After about a day of relentless hacking, I was able to get the first function, oAuth() to work. That logs, well, my user data. However, for the life of me, I cannot figure out what is holding up request. I do get this error: Request failed for returned code 403. Truncated server response: {"errors":[{"message":"SSL is required","code":92}]}. Googling this didn't turn up much. I'm guessing that the issue is somewhere in Roptions. Any help would be appreciated, and I can try to provide further clarification if needed.

Eureka! Here's the solution. The irony is that I had had something like this before, but had dismissed it. Turns out https was my biggest problem. I'll feast on humble pie tonight.

script to send tweet

//post tweet
function oAuth() {
  var CONSUMER_KEY = "*************************";
  var CONSUMER_SECRET = "**************************************************";
  ScriptProperties.setProperty("TWITTER_CONSUMER_KEY", CONSUMER_KEY);
  ScriptProperties.setProperty("TWITTER_CONSUMER_SECRET", CONSUMER_SECRET);
  var oauthConfig = UrlFetchApp.addOAuthService("twitter");
  oauthConfig.setAccessTokenUrl("https://api.twitter.com/oauth/access_token");
  oauthConfig.setRequestTokenUrl("https://api.twitter.com/oauth/request_token");
  oauthConfig.setAuthorizationUrl("https://api.twitter.com/oauth/authenticate");
  oauthConfig.setConsumerKey(ScriptProperties.getProperty("TWITTER_CONSUMER_KEY"));
  oauthConfig.setConsumerSecret(ScriptProperties.getProperty("TWITTER_CONSUMER_SECRET"));
  var options = {muteHttpExceptions: true,oAuthServiceName:'twitter',oAuthUseToken:'always'}
  var url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
  var response = UrlFetchApp.fetch(url, options).getContentText();
  Logger.log(response);
}
function postTweet() {
  oAuth();
  Logger.log('oAuth complete');
  var status='Test tweet';
  var options = {
    "method": "post",
    "oAuthServiceName": "twitter",
    "oAuthUseToken": "always",
    "payload":{"status":status}
  };
  var url = "https://api.twitter.com/1.1/statuses/update.json";
  Logger.log('begin post');
  var request = UrlFetchApp.fetch(url, options);
  Logger.log('post complete');
}

When you register your Twitter app, you have to check the option Allow this application to be used to Sign in with Twitter. This prevents continual Authorize popups. Also, the tweet text CANNOT contain single quotes (').
