title: REST method in calling google translate API
body: <p>I want to access the Google Translate APIv2. Here is the url:</p>
  
  <blockquote>
    <p><a href="https://www.googleapis.com/language/translate/v2?key=INSERT-YOUR-KEY&amp;q=hello%20world&amp;source=en&amp;target=de" rel="nofollow">https://www.googleapis.com/language/translate/v2?key=INSERT-YOUR-KEY&amp;q=hello%20world&amp;source=en&amp;target=de</a></p>
  </blockquote>
  
  <p>I already have the key and this url is working fine if I am using it in the browser address bar.</p>
  
  <p>My problem is that I do not know how to call this url using REST. I want to get the result stored in a variable.</p>
