リアクション・メッセージを送る

このコードでは、Messages API を使って WhatsApp リアクションメッセージを送信する方法を説明します。WhatsApp reaction メッセージタイプでは、受信したメッセージに絵文字で反応することができます。

と同様に to そして from Numbersでは、このメッセージタイプには2つの重要な情報が必要です：

について message_uuid 反応するメッセージのこれは受信したインバウンド・メッセージのボディに存在する。
について emoji をリアクションとして使用します。これは例えば😀のような絵文字そのものでもかまいません。

重要： メッセージ未送信の場合、WhatsAppは初回メッセージ送信時にテンプレートを要求します。詳しくは WhatsAppトピックの理解.

例

各コード・スニペットで使用されているすべての変数の説明を以下に示します：

キー	説明
`JWT`	Used to authenticate your request. See Authentication for more information, including how to generate a JWT.
`VONAGE_APPLICATION_ID`	The Vonage Application ID.
`VONAGE_PRIVATE_KEY_PATH`	Private key path.
`MESSAGES_API_URL`	There are two versions of the API, each with their own endpoints. For production the previous Messages API endpoint was `https://api.nexmo.com/v0.1/messages`, the new one is `https://api.nexmo.com/v1/messages`. For sandbox testing the Messages API endpoint is `https://messages-sandbox.nexmo.com/v0.1/messages` or `https://messages-sandbox.nexmo.com/v1/messages`, depending on which version you have set in the sandbox dashboard.
`WHATSAPP_NUMBER`	The WhatsApp number that has been allocated to you by Vonage. For sandbox testing the number is 14157386102.
`TO_NUMBER`	Replace with the number you are sending to. E.g. `447700900001`
`MESSAGE_UUID`	The UUID of the specific message.
`EMOJI`	The emoji to send in the message.

注：先頭の + または 00 電話番号を入力する場合は、447700900000のように国番号から入力してください。
