I am trying to test an API on delhivery logistic test environment but keep getting same result each time even I am entering API key on there testing environment.

this is there test environment code below:

const options = {
  "method": "GET",
  "hostname": "staging-express.delhivery.com",
  "port": null,
  "path": "/c/api/pin-codes/json/",
  "headers": {
    "Accept": "application/json",
    "Authorization": "Token api-token-key Pass Token as \"Token XXXXXXXXXXXXXXXXXX\""
  }
};

const req = http.request(options, function (res) {
  const chunks = [];

  res.on("data", function (chunk) {
    chunks.push(chunk);
  });

  res.on("end", function () {
    const body = Buffer.concat(chunks);
    console.log(body.toString());
  });
});

req.end();

but its showing this result even I am filling both required field
