The `Messenger Template node` is used to send any of the supported template in **Facebook Messenger**:

- [Generic template](https://developers.facebook.com/docs/messenger-platform/send-messages/template/generic)

- [Button template](https://developers.facebook.com/docs/messenger-platform/send-messages/template/list)

- [Media template](https://developers.facebook.com/docs/messenger-platform/send-messages/template/media)

- [Product template](https://developers.facebook.com/docs/messenger-platform/send-messages/template/product)

- [Receipt template](https://developers.facebook.com/docs/messenger-platform/send-messages/template/receipt)

- [Customer Feedback Template](https://developers.facebook.com/docs/messenger-platform/send-messages/templates/customer-feedback-template)

For the last two templates it’s not available an advanced UI, just a JSON editor where to copy and paste the payload for the desired template (read the **Facebook** documentation about how to generate it).

Two _generic templates_ can be combined together in a carousel by simply chaining `Messenger Template node` (to maximum of 10). Each template can have a maximum of 3 buttons, `title` and `subtitle` are limited to 80 chars.

_Generic templates_ and _button template_ can have up to 3 buttons, see [Buttons node](https://app.notion.com/p/b8f3ea33948049cca7b94491061183f4)  for a complete list of available buttons (only `quick-reply` and `location` are not available here).

In order to create a generic template in a upstream `Function node`

```javascript
msg.payload = {
  templateType: 'generic',
  title: 'my title',
  subtitle: 'I am a sub title',
  imageUrl: 'http://image.server.com/cover.png',
  buttons: [
    {
      type: 'url',
      url: 'http://javascript-jedi.com',
      label: 'Javascript Jedi'
    }
  ]
}
```

or in order to pass a collection of elements for the carousel

```javascript
msg.payload = {
  elements: [
    {
      templateType: 'generic',
      title: 'my title',
      subtitle: 'I am a sub title',
      imageUrl: 'http://image.server.com/cover.png',
      buttons: [
        {
          type: 'url',
          url: 'http://javascript-jedi.com',
          label: 'Javascript Jedi'
        }
      ]
    },
    {
      templateType: 'generic',
      title: 'another title',
      subtitle: 'Second sub title',
      imageUrl: 'http://image.server.com/cover2.png',
      buttons: [
        {
          type: 'url',
          url: 'http://javascript-jedi.com',
          label: 'Javascript Jedi'
        }
      ]
    }
  ]
}
```

Some additional parameters can like _shareable_ or _aspectRatio_ can be defined using the [Params node](https://app.notion.com/p/d8b27db3949c475184923af913563833) .
