WhatsAppメッセージテンプレート(MTM)の送信

このコードスニペットでは、Messages API を使って WhatsApp メッセージテンプレートメッセージ (MTM) を送信する方法を説明します。

重要： 顧客からメッセージが届いた場合、24時間以内に自由形式のメッセージを返信する必要があります。それ以降はメッセージテンプレート(MTM)を使用する必要があります。顧客からメッセージが届いていない場合、WhatsAppが初めてメッセージを送信する際、テンプレートが必要となります。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
`VONAGE_APPLICATION_ID`	The Vonage Application ID.
`VONAGE_APPLICATION_PRIVATE_KEY_PATH`	Private key path.
`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.
`VONAGE_WHATSAPP_NUMBER`	Refer to `WHATSAPP_NUMBER` above.
`VONAGE_NUMBER`	Refer to `WHATSAPP_NUMBER` above.
`TO_NUMBER`	Replace with the number you are sending to. E.g. `447700900001`
`WHATSAPP_TEMPLATE_NAME`	The name of the template created in your WhatsApp Business Account.

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。
