Dialogflowから感情分析のAPIを使ってアプリ開発をしたいと考えています。

しかし、Dialogflowを介さずに実行するとうまくいくのですが、Dialogflowをかいすと以下のようなエラーがでます。

{ Error: getaddrinfo ENOTFOUND api.apitore.com api.apitore.com:443
    at errnoException (dns.js:28:10)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:76:26)
  code: 'ENOTFOUND',
  errno: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'api.apitore.com',
  host: 'api.apitore.com',
  port: 443

Dialogflowでは、APIは使えないのでしょうか。

よろしくお願いいたします。
