            facebook: {
                attachment: {
                    type: "template",
                    payload: {
                        template_type: "generic",
                        elements: [{
                            title: "title",
                            subtitle: "subtitle",
                            image_url: "https://external.xx.fbcdn.net/safe_image.php?d=AQBIbeQ2vl8bb5tl&url=http%3A%2F%2Fimagizer.imageshack.us%2F196x92f%2F924%2FySQ7a9.png&_nc_hash=AQAv9cZ-0jAr9REX",
