How To Auto Tweet YouTube Activity?

YouTube has removed the option to auto-tweet your activity such as likes and favorites, there are still some work-arounds.
All it takes is a few steps, and we have a couple of options:

1. Use IFTTT.com to set up automatic sharing.

I like IFTTT (If This Then That). After you sign up you notice there are applets to tweet your youtube likes, including one from Google itself. But I used to prefer to make my own by setting up a RSS to Twitter feed.

2. Get the RSS feed link for your likes, uploads, favorites.  [limited options]

I like this method and it used to work pretty well, but now it seems much more limited.
Unless you're a script genius and can set up your own api access to your YouTube channel (I haven't gotten into that yet...), just use IFTTT or something that does it for you.

The youtube RSS feeds only show the last 20 items. And it adds two tags, the published & updated tags in the RSS, which might confuse some services like IFTTT and not publish the recently added items.

But if you have your own way of publishing RSS to twitter, here's how to get the link.

All your liked videos are in a playlist called Liked Videos. 

Copy the id itself, the part after ?list=

An RSS URL for a playlist looks like this:

https://www.youtube.com/feeds/videos.xml?playlist_id=PLFgquLnL59alW3xmYiWRaoz0oM3H17Lth

Replace the part after id= with your playlist id. 

Test the link in a browser to make sure the rss feed has your playlist data. It should show the recent 20 items in your playlist.
