Sending An Image Back To A User

If you want to return an image back to a user, you can use the following JSON as a webhook response.

{
  "recipient":{
    "id":"{{1.fbuser.fbid}}"
  },
  "message":{
"raw": {
    "attachment":{
      "type":"image", 
      "payload":{
        "url":"imageURL", 
        "is_reusable":false
      }
    }
  }
}
}
