コンセプトから初版まで
より少ないステップで

JavaScriptコードとの関係性が強いJSONコードが、メッセージングや通話などのさまざまな機能につながり、最終的にユーザーに届きます。

Node.jsにより、イベント駆動型のマイクロサービスを構築

Node.jsを使用することにより、拡張性に優れた、商用レベルのイベント駆動型Twilioアプリケーションを作成できます。安定性に不安を抱くことなく、イノベーションを起こせます。短期間の開発を迅速に行うことができます。StudioアプリケーションとIVRシステムにはカスタムロジックを使用します。

データベースに関連付けられたNode jsのコードは、サードパーティのさまざまなサービスを統合しています。

サードパーティのエンドポイントとの統合

Node.jsの機能とnpmエコシステムを利用し、データの変換とフィルタリングを行うことにより、任意のサードパーティシステムと統合できます。外部APIリクエストを簡単に作成し、Webhookの設定により、Twilio製品や外部システムからデータを取り込むことができます。

Functionsとの関連性が強いStudioは、メッセージングや通話などのさまざまなアクションにつながります。

お客様のコードをTwilioで

強力なAPIの構築、複雑な統合、IVRへのカスタムロジックの追加など、アイデアを短期間で実現できます。Twilio Functionsに運用のオーバーヘッドを任せることで、より短期間で市場に投入することができます。

Twilio Codeは、世界中のメトリックスの成長を支援しています。

自動スケーリングと透明性のある料金

Twilioのサーバーレス系プロダクトは、ゼロ需要からピーク需要まで自動的にスケーリングし、組織のコストを最小限に抑える従量課金制のビジネスモデルを特徴としています。
