How do I post a Tweet to Twitter using Raw Code in Javascript from inside Unity?

Hey guys, as the title says, I am looking for a way to post a tweet to twitter inside of unity using Javascript.

I don't Completely understand the process of sending a tweet. I have already signed my app up on Twitters Dev Page, and have a Consumer Secret and Consumer Key, I have downloaded "Let's tweet in Unity" from the asset store, but as far as I can tell it does not work. I input my key's and secrets, and it also asked me for a PIN?

Its all so confusing to me, Isn't there a way I can just send information to a server with the username, password, and tweet message text? If so, please explain!

Social features are very important in mobile games these days, and I want to learn how I can get my foot in that door too, I just need some help from you guys!

Thanks for Reading, Zadd
