+Notice also that `facebook_postback` events trigger the `message_received` event as well. That is why messages will have the `type` field as well. When the message is directly from the user (i.e. onlye `message_received` event) `type` will be set to `"user_message"` and when the message is originated in a `facebook_postback` then `type` will be set to `facebook_postback`.
