Aqui, tu podes criar uma função, para pegar o template que tu quiser e aplicar na tua mensagem de volta.

Eu encontrei este tutorial para watson diálogo, eu gostaria de saber como faço para usá-lo em watson conversa, eu quero implementar apenas a parte da estrutura do messenger, para o meu watson conversation possa enivar imagens, botões
https://github.com/nheidloff/facebook-watson-bot/blob/master/app.js

function sendButtonMessage(recipient, text, buttons) {
request({
url: 'https://graph.facebook.com/v2.6/me/messages',
qs: {access_token:token},
method: 'POST',
json: {
recipient: {id:recipient},
message: {
"attachment":{
"type":"template",
"payload":{
"template_type":"button",
"text":text,
"buttons": buttons
}
}
}
}
},
function(error, response, body) {
if (error) {
console.log('Error sending message: ', error);
} else if (response.body.error) {
console.log('Error: ', response.body.error);
}
});
}

function sendGenericTemplateMessageWithTweets(recipient, author, imageUrl, title, url) {
request({
url: 'https://graph.facebook.com/v2.6/me/messages',
qs: {access_token:token},
method: 'POST',
json: {
recipient: {id:recipient},
message: {
"attachment":{
"type":"template",
"payload":{
"template_type":"generic",
"elements": [
{
"title":author,
"image_url":imageUrl,
"subtitle":title,
"buttons":[
{
"type":"web_url",
"url":url,
"title":"View Tweet"
}
]
}
]
}
}
}
}
},
function(error, response, body) {
if (error) {
console.log('Error sending message: ', error);
} else if (response.body.error) {
console.log('Error: ', response.body.error);
}
});
}
