Sending an Image card with a URL Button

In this example, the code would return an image card with a button that links off to the Bot Platform website.

{
  "recipient": {
    "id": "USER_ID"
  },
  "message": {
    "raw": {
      "attachment": {
        "type": "template",
        "payload": {
          "template_type": "generic",
          "elements": [{
            "title": "The Bot Platform",
            "subtitle": "Bots bots bots",
            "image_url": "https://thebotplatform.com/assets/img/brand-logo-@2x.png",
            "buttons": [{
              "type": "web_url",
              "url": "https://thebotplatform.com",
              "title": "Website"
            }]
          }]
        }
      }
    }
  }
}
