Google URL Shortener API in Ruby

Continuous Integration


Basic Usage

Shorten a long URL

url = Googl.shorten('')

=> ""

=> ""

=> ""
=> ""

Expand a short URL

url = Googl.expand('')

=> ""


The Google URL Shortener API supports the OAuth and ClientLogin mechanisms for authenticating.

For shorten requests, each short URL for an authenticated user is unique, and thus will gather unique click statistics. In addition, it shows up on the user's dashboard at


client = Googl.client('', 'my_valid_password')

url = client.shorten('')

Go to to see URL statistics.


Google supports three flows of OAuth 2.0

  • The client-side flow for JavaScript applications running in a browser. (TODO)

  • The server-side flow for web applications with servers that can securely store persistent information.

  • The native application flow for desktop and mobile applications.

Today, gem googl support only server-side and native application.

Server-side web applications

You'll need to register your application with Google to get a client_id and record the redirect_uri you'd like to use. See the Registering your app with Google section for details on how to register.

client = Googl::OAuth2.server("client_id", "client_secret", "redirect_uri")

Redirect your users to


After the user approves access or chooses not to, we'll redirect to the redirect_uri you passed us and append either an authorization code.

=> true

Now you can get a user's history, shorten url, etc…

history = client.history
=> 19

url = Googl.shorten('')

Native applications

You'll need to register your application with Google to get a client_id and record the special redirect_uri: urn:ietf:wg:oauth:2.0:oob. See the Registering your app with Google section for details on how to register.

When you use this redirect_uri, instead of redirecting the user's browser to a page on your site with an authorization code, Google will display the authorization code or error response in the title of the page and a text field with instructions for the user to copy and paste it in to your application. Your application can either monitor the window title of a web-view or browser window it launches and close it once the authorization code appears or prompt the user to copy and paste the code.

client = Googl::OAuth2.native("client_id", "client_secret")

Open a browser or a webview to the OAuth dialog at


In the native app flow, after the user approves access, we'll display the authorization code in the title of the page and in a text input with instructions for the user to copy and paste the code to your application

code = "copied code"
=> true


Expands a short URL or gets creation time and analytics

For analytics and additional information to return (using the :projection parameter)

:full                    returns the creation timestamp and all available analytics
:analytics_clicks        returns only click counts
:analytics_top_strings   returns only top string counts (e.g. referrers, countries, etc)

Get Analytics

url = Googl.expand('', :projection => :full)
=> "Chrome"
=> "11"

A summary of the click analytics for the short and long URL

Analytics details for a particular window of time; counts in this object are of clicks that occurred within the most recent window of this length.

Number of clicks on this short URL. Replace (*) for all_time, month, week, day or two_hours*.short_url_clicks

Number of clicks on all short URLs pointing to this long URL.*.long_url_clicks

Top referring hosts, e.g. “”; sorted by (descending) click counts. Only present if this data is available.*.referrers

Top countries (expressed as country codes), e.g. “US” or “DE”; sorted by (descending) click counts.*.countries

Top browsers, e.g. “Chrome”; sorted by (descending) click counts.*.browsers

Top platforms or OSes, e.g. “Windows”; sorted by (descending) click counts.*.platforms

Gets a user's history of shortened URLs. (Authenticated)
