Currently i working for read all order data through json api.
I am getting the success response in postman but not working in node.
here is not code which i have used to get the response, can someone let me know the flow which i have missing in it.

var request = require("request");

var options = { method: 'GET',
  url: 'https://mydomain.com/wc-api/v3/customers',
  qs:
   { oauth_consumer_key: '',
     oauth_signature_method: '',
     oauth_timestamp: '',
     oauth_nonce: '',
     oauth_version: '1.0',
     oauth_signature: '=' },
  headers:
   { 'postman-token': '',
     'cache-control': 'no-cache',
     authorization: '' },
  form: { '': '' } };

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(body);
});
