How to render button or quick replies in whatsapp using twilio?

[S0024009236]

Hello experts,

I was trying to connect sap cai with whatsapp. I referred to the blog SAP CAI WITH WHATSAPP. I had to make some minor changes as sap cai has changed the way of authentication and hence default sdk can't be used.

Following is the code I wrote in twilio function and the response of it. How do i send buttons or quick replies to whaatsapp?

//Code in twilio function
exports.handler = function(context, event, callback) {
    let twiml = new Twilio.twiml.MessagingResponse();   
    let superagent = require('superagent'); 
   
superagent
 .post("https://api.cai.tools.sap/build/v1/dialog")
  .send({ message: { content: event.Body, type:"text" }, conversation_id: event.From})
  .set("Authorization", "<Bearer using client id and secret>); 
  .set("X-Token", "<Developer Token>")
  .set("Content-type", "application/json")
  .then(function(res) {
   data = res.text;
   //console.log(data);
   twiml.message(data);
   callback(null, twiml);
  });
        
 
};

//response
