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`	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`.
`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.

If you do not have an application you can create one. Make sure you also configure your webhooks.

Add the following to send-template.sh:

Save this file to your machine and run it:

bash send-template.sh

When you run the code a Facebook message template is sent to the recipient. In this example the message is an airline boarding pass.
