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.
`BASE_URL`	For production use the base URL is `https://api.nexmo.com/`. For sandbox testing the base URL is `https://messages-sandbox.nexmo.com/`.
`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.
`FB_SENDER_ID`	Your Page ID. The `FB_SENDER_ID` is the same as the `to.id` value you received in the inbound messenger event on your Inbound Message Webhook URL. For sandbox testing this is `107083064136738`.
`VONAGE_FB_SENDER_ID`	Refer to `FB_SENDER_ID` above
`FROM_ID`	Refer to `FB_SENDER_ID` above
`FB_RECIPIENT_ID`	The PSID of the user you want to reply to. The `FB_RECIPIENT_ID` is the PSID of the Facebook User you are messaging. This value is the `from.id` value you received in the inbound messenger event on your Inbound Message Webhook URL.
`TO_ID`	Refer to `FB_RECIPIENT_ID` above.
`FILE_URL`	The link to the file to send. Can be ZIP, CSV, PDF or any other type supported by Messenger.
