const googleIapAuth = new GoogleIapAuth("<oauth_client_id>", keyData);
const authorizedGot = got.extend({
  hooks: {
    beforeRequest: [
      async options => {
        options.headers.Authorization = `Bearer ${await googleIapAuth.getToken()}`;
      }
    ]
  },
  responseType: "json",
  followRedirect: false,
  mutableDefaults: true
});

(async () => {
  const response = await authorizedGot(
    "https://some.iap.protected.resource.com/"
  );
  console.log(response.statusCode);
  console.log(response.body);
