Send a Message Template
In this code snippet you learn how to send a Facebook message template using a custom object with the Messages API.
Example
Ensure the following variables are set to your required values using any convenient method:
| Key | Description |
|---|---|
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 |
For production use the Messages API endpoint is https://api.nexmo.com/v0.1/messages. For sandbox testing the Messages API endpoint is https://messages-sandbox.nexmo.com/v0.1/messages. |
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. |
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. |
LOGO_IMAGE_URL |
An optional logo image. |
HEADER_IMAGE_URL |
An optional header image. |
ABOVE_BAR_CODE_IMAGE_URL |
An optional image for above the bar code. |
