title: How direct call the amazon personalize service?
body: <p>Good day!
  How I can call from the backend(nodejs) the amazon service?</p>
  
  <p>I found library aws-sdk-js, but not sure how to find exact URL of my service.</p>
  
  <p>Moreover, do I need to use S3 to manage input data and output data?
  In the Personalize server settings I can find "Batch inference jobs" with inputs for these matter.<a href="https://i.stack.imgur.com/zeKCB.png" rel="nofollow noreferrer">screenshot</a></p>
