音声メッセージの送信

Amazon Pinpoint API を使用して、特定の電話番号に音声メッセージを送信できます。このセクションでは、 AWS SDK を使用して Amazon Pinpoint SMS および音声 API を介して音声メッセージを送信するために使用できる完全なコード例を示します。アカウントは本番環境に存在し、音声メッセージを送信できるアクティブな発信元 ID を持っている必要があります。

エンドポイント、セグメント、チャネルのコード例については、「コード例」を参照してください。

Java

この例を使用して、AWS SDK for Java を使用して音声メッセージを送信します。この例は、SDK for Java がすでにインストールされ、設定されていることを前提としています。詳細については、『 AWS SDK for Java デベロッパーガイド』の「使用開始」を参照してください。

この例では、共有認証情報ファイルを使用して、既存のユーザーのアクセスキーとシークレットアクセスキーを指定することを前提としています。詳細については、「 AWS SDK for Java デベロッパーガイド」の「開発用の AWS 認証情報とリージョンの設定」を参照してください。
