How to send a message in a Twilio Conversation

Question

How do you send a new message to a Twilio Conversation in node.js?

I found this sample code from Twilio, but I don't know how to get messagingServiceSid for my Conversation.

// Download the helper library from https://www.twilio.com/docs/node/install
// Your Account Sid and Auth Token from twilio.com/console
// and set the environment variables. See http://twil.io/secure
const accountSid = process.env.TWILIO_ACCOUNT_SID;
const authToken = process.env.TWILIO_AUTH_TOKEN;
const client = require('twilio')(accountSid, authToken);

client.messages
  .create({
     body: 'Revenge of the Sith was clearly the best of the prequel trilogy.',
     messagingServiceSid: 'MG9752274e9e519418a7406176694466fa',
     to: '+441632960675'
   })
  .then(message => console.log(message.sid));

Answer 1

Two options:

1) Graphical via the Twilio Console

2) Programmatically via the Twilio Rest API

The Service Resource gets you started. You would also need to associate phone numbers with your messaging service, you can do this via the PhoneNumber Resource . Note that the API is currently in Public Beta.

Answer 2

Separate answer for the Conversations API :

First create a conversation and note down the conversation SID (starts with CH , here outputted with console.log(conversation.sid) ):

const accountSid = process.env.TWILIO_ACCOUNT_SID;
const authToken = process.env.TWILIO_AUTH_TOKEN;
const client = require('twilio')(accountSid, authToken);

client.conversations.conversations
                    .create({friendlyName: 'My First Conversation'})
                    .then(conversation => console.log(conversation.sid));

Then add an SMS participant to a Conversation (this is where you need your SMS-enabled Twilio number and the recipient number).

Now you can use the Conversation Message Resource to create messages which will be received by all participants of the conversation.
