With the 140 character limit that comes with developing a Twitter app, I needing a URL shortening service with a simple, easy to use API. Conveniently the bit.ly API works great if you are looking for s simple URL shortener for dynamic use.
Just had to sign up a free account, then spent a few minutes reading over the bit.ly API documentation. Just send a simple REST request and you get a simple JSON response. Doesn’t really get much simpler than that. An XML response is also available as well.
Very cool API and one that worked perfectly for the task at hand.
