Here's how to get an API key (required) quickly:

• Head over to https://console.developers.google.com/home/dashboard and create a new project.
• Select 'API Manager' from the hamburger menu
• Hit 'URL Shortener API' under 'Other Popular APIs'
• Click 'Enable'
• In 'Credentials' section, click 'Create Credentials' and select 'API key'. Select the 'Browser key' option.
  
  And you'll get a shiny, new API key!

Now, all you need to do is put the API key in the var api_key in the script you can download from here: Github.
