URL Shortener has integrated with Google private browsing way, it shows neat stats and it automatically generates QR codes, it’s fast, it hardly goes down But, Goo.gl did not provide an official API for blogger and plenty of applications did not support it. Twitter clients automatically shorten links after posting on it like t.co/xxxx, and many of browser extensions create short links, while CMS plugins convert the links so that people can share them.

Now alternative applications will use Goo.gl because there is an official API that is quite simple to use and contains substantial limit more than 1,000,000 requests per day. You will use the Google URL Shortener API to programmatically move with this service and to develop applications that use straightforward protocol strategies to store, share, and manage Goo.gl short URLs. The API helps you to produce short links, rewrite Goo.gl links, and browse stats and appearance up a user's history.
