Etsy counter

Hello,
I'm trying to create a counter for Etsy platform which has its own API. I have already tried it via console ( with XMLHttpRequest()) and everything works fine. And have started working with ESP8266.
Wifi connected, the request is sent, but I receive not the same answer as for example when putting the same URL in the browser.

My function:

function getPage() {
  require("http").get("https://openapi.etsy.com/v2/shops", function(res) {
   console.log("Response: ",res);
     res.on('data', function(data) { contents += data; });
     res.on('close', function(contents) { console.log(contents); });
  });
}
getPage();

in console I see:

=undefined
Response:  httpCRs {
  "headers": {
    "Location": "https://openapi.etsy.com/v2/shops",
    "Server": "BigIP",
    "Content-Length": "0",
    "Accept-Ranges": "bytes",
    "Date": "Thu, 20 Jul 2017 03:06:32 GMT",
    "Via": "1.1 varnish",
    "Age": "0",
    "Connection": "close",
    "X-Served-By": "cache-yyz8330-YYZ",
    "X-Cache": "MISS",
    "X-Cache-Hits": "0",
    "X-Timer": "S1500519992.012622,VS0,VE37"
   },
  "httpVersion": "1.1",
  "statusCode": "302",
  "statusMessage": "Found"
 }
false

But if I put the same request in browser "https://openapi.etsy.com/v2/shops" I at least see "API request missing api_key or valid OAuth parameters" (just don't want to show my ApiKey).

As for other links "http://www.pur3.co.uk/hello.txt" or "http://samples.openweathermap.org/data/2.5/weather?q=London,uk&appid=b1b15e88fa797225412429c1c50c122a1" everything is ok.

So in result I'm see 'the wall' before next steps.

Could anyone help to solve it?

Thanks
