#philnash had a solution [here][1] that I tried and had a problem - I'm using Twilio's Cloud Functions and getting no intellisense on client.messages - any idea how to reference the correct library
client.messages.create({
In the screenshot, you spelled client wrong, cleint.
exports.handler = function(context, event, callback) {
const twilioClient = context.getTwilioClient();
twilioClient.messages
.create({
body: 'Hello World',
to: '+14075551212',
from: '+18025551212 ',
}).then(message => {
console.log('Created call using callback');
console.log(message.sid);
callback();
})
.catch(error => {
console.log(error);
callback("error");
});
};
You should update the Twilio client library version as well, 3.29.2 is pretty old.

I want to know the current callers(client) Phone Number and then be able to verify it from my HubSpot CRM to see which language my client speaks. Then Enqueue the call to the agent that speaks the language or give the Caller an option to choose the preferred language.
Anyhoo
Right now my goal is to just get the number of the caller(client).
exports.handler = function(context, event, callback) {
console.log(event);
//const request = require('request');
//const client = require('twilio');
const res = new Twilio.Response();
res.appendHeader('Access-Control-Allow-Origin', '*');
res.appendHeader('Access-Control-Allow-Methods', 'OPTIONS POST');
res.appendHeader('Content-Type', 'application/json');
res.appendHeader('Access-Control-Allow-Headers', 'Content-Type');
const fetch = require("node-fetch");
var phoneNumber = event.From; //|| [ "+63XXXXXXXXXX" ];
const apiUrl = "https://myapiurl.com/contact-details.php?number="+phoneNumber;
fetch(apiUrl,{
method: 'GET',
headers: { 'Content-Type': 'application/x-www-form-urlencoded'}
})
.then( response =>{
return response.json();
})
.then(json=>{
console.log(json);
res.setBody(json);
callback(null,res);
})
.catch(error=>{
console.log(error);
callback();
});
};
Also let me know if there is a better way to do it.

Your code shows you getting event.From. This is the number of the person calling, so you have already done it!
I have Twilio Studio calling a Twilio Function and need it to send email to a variable list (small list) of emails. This question is mostly around looping through them as I can pass variables just fine. I have an array of emails to send a text to and am in a Twilio Function. But all examples I find online are about sending to just ONE. Part of me thinks this needs to be a Twilio Function calling another Twilio function (one loops, the other sends Emails)... but I can't figure out a way to do that. If I could contain it to one Twilio function, that would be great.
I have Twilio Studio calling a Twilio function. I need to keep this all on Twilio... so looping through via PHP and running functions one at a time through there doesn't work. I need this to run on Twilio's serverless setup.
Here's an example of what I have that works:
exports.handler = function(context, event, callback) {
// using SendGrid's v3 Node.js Library
// https://github.com/sendgrid/sendgrid-nodejs
const sgMail = require('#sendgrid/mail');
sgMail.setApiKey(context.SENDGRID_API_KEY);
const msg = {
to: 'me#example.com',
from: 'noreply#example.com',
templateId: 'my-id-goes-here',
dynamic_template_data: {
recipient_name: 'John Smith'
}
};
sgMail.send(msg).then(response => {
let twiml = new Twilio.twiml.MessagingResponse();
callback(null, twiml);
})
.catch(err => {
callback(err);
});
};
Here's me trying to loop through in similar fashion and failing
exports.handler = function(context, event, callback) {
const sgMail = require('#sendgrid/mail');
sgMail.setApiKey(context.SENDGRID_API_KEY);
var responder_emails = 'me#example.com,me+test1#example.com';
var emails_a = responder_emails.split(',');
emails_a.forEach(function(responder_email) {
const msg = {
to: responder_email,
from: 'noreply#example.com',
templateId: 'my-id-goes-here',
dynamic_template_data: {
recipient_name: 'John Smith'
}
};
sgMail.send(msg);
});
callback();
};
I can pass in multiple emails into a Twilio function... I'm just not sure how to loop through correctly.
Heyo. Twilio Evangelist here. 👋
In your first example, you rightfully waited for the send call to be done by using then. In your second example, you missed that. You run several send calls but immediately call callback without waiting.
A fixed (roughly prototyped version) could look as follows.
exports.handler = function(context, event, callback) {
const sgMail = require('#sendgrid/mail');
sgMail.setApiKey(context.SENDGRID_API_KEY);
var responder_emails = 'me#example.com,me+test1#example.com';
var emails_a = responder_emails.split(',');
Promise.all(emails_a.map(function(responder_email) {
const msg = {
to: responder_email,
from: 'noreply#example.com',
templateId: 'my-id-goes-here',
dynamic_template_data: {
recipient_name: 'John Smith'
}
};
return sgMail.send(msg);
})).then(function() {
callback();
}).catch(function(e) {
callback(e);
})
});
You have already an array of emails because you called split. You can use this array in combination with Array.map and Promise.all.
Map basically iterates over your array and lets you create a new array with whatever you return from the function inside of map. What the code above does is that it transforms [email, email] to [Promise, Promise]. The promises are the return value of sgMail.send.
Now, that you have an array holding promises that will resolve when sendgrid accepted your call, you can use Promise.all. This method waits for all the promises to be resolved (or rejected) and returns itself a new promise which you can use then with. When all sendgrid calls are done it's time to finish the function by calling the function callback.
Side note: this "map/Promise.all" trick performs all send grid calls in parallel. There might be situations where you want to call them one after another (saying you are doing a lot of calls and run into rate limiting).
Hope that helps and let me know how it goes. :)
I have created a Twilio function that I would like to use to send my affiliate referral link to subscribers of an application that come through my channel.
It works fine with a static to / from number, however I would like to make the "to" field a dynamic variable that can be manipulated via a HTTP/Webhook POST when a Zapier detects a new subscriber to my Mailchimp mailing list and pass their phone number as the variable.
I am also unclear what I need to do to authenticate the client (Zapier) that is making the POST as I do not want the function open to the world to use, if any insights can be shared on this it would be sincerely appreciated - I am a very inexperienced programmer trying to learn very quickly!
#philnash - thanks for your suggestion, implementing it slowly!
Many thanks in advance!
exports.handler = function(context, event, callback) {
const appCodes = ['code1', 'code2', 'code3', 'code4']
var smsBody = refCode ();
function refCode () {
return appCodes[Math.floor((Math.random() * appCodes.length))];
};
context.getTwilioClient().messages.create({
to: '+11112223333', // How do I make this dynamic from HTTP/Zapier Webhook POST???
from: '+1444555666',
body: `Get the App: ${smsBody}`
}).then(msg => {
callback(null, msg.sid);
}).catch(err => callback(err));
}

I presume the Zapier webhook is sending the details, including the phone number, as the body of the POST request.
All the parameters in a request body appear on the event object that is passed into your handler. You probably want to run a test where you print out the contents of the event object to see what you are being passed. You can do this with:
exports.handler = function(context, event, callback) {
for (let key in event) {
console.log(`${key}: ${event[key]}`);
}
// ... rest of the function
}
Then, when you figure out what parameter is storing the number, you can use that in the call to create the message.
Let me know if that helps at all.
Try this:
exports.handler = function(context, event, callback) {
for (let key in event) {
console.log(`${key}: ${event[key]}`);
}
// ... rest of the function
callback(null, 'complete');
};
Thanks everyone for your input, it was sincerely appreciated! I was able to solve this with the following code:
exports.handler = function(context, event, callback) {
const appCodes = ['code1', 'code2', 'code3', 'code4']
var smsBody = refCode ();
var subNum = event.primaryPhone || 'There is no subscriber number'; // primaryPhone sent via HTTP post to twilio function
function refCode () {
return appCodes[Math.floor((Math.random() * appCodes.length))];
};
context.getTwilioClient().messages.create({
to: `${subNum}`, // parameters & values recieved from HTTP POST are available within the twilio functions "event" context
from: '+1444555666',
body: `Get the App: ${smsBody}`
}).then(msg => {
callback(null, msg.sid);
}).catch(err => callback(err));
}
I'm trying to implement a Twilio function to (1) forward calls to my personal phone, (2) send a "heads up" SMS just before, and (3) say a whisper prior to connecting. I've been able to set up Twilio to do any 2 of the previous 3 things but never the 3 at the same time!
exports.handler = function(context, event, callback) {
// Get an initialized Twilio API client
const client = context.getTwilioClient();
twilioClient.messages.create({
to: 'PERSONAL_PHONE',
from: 'TWILIO_PHONE',
body: 'Incoming!!!'
}).then(function() {
const twiml = new Twilio.twiml.VoiceResponse();
twiml.dial.number({ url: WHISPER_URL }, 'PERSONAL_PHONE');
callback(null, twiml);
});
};
When implementing this, it sends the SMS but the call never connects (and the calling party hears an error message).
Would really appreciate a lesson here :)
Thank you!
Btw, I found a solution:
exports.handler = function(context, event, callback) {
// Get an initialized Twilio API client
const client = context.getTwilioClient();
twilioClient.messages.create({
to: 'NUMBER',
from: 'TWILIO_PHONE',
body: 'Incoming!!!'
}).then(function() {
const twiml = new Twilio.twiml.VoiceResponse();
const dialobj = twiml.dial();
dialobj.number({url:'WHISPER_URL'},'NUMBER');
callback(null, twiml);
});
};
I'm trying to set up messages delivery status check with twilio. For some reasons twilio statusCallback doesn't fire. Could you please help me to find an error?
Here is a file where I do initialization and send messages:
const Twilio = require('twilio');
const {
TWILIO_ACCOUNT_SID,
TWILIO_AUTH_TOKEN,
TWILIO_PHONE_NUMBER
} = require('config');
const client = new Twilio(TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN);
module.exports = {
send: (body, phoneNumber) => client.messages.create({
body,
to: phoneNumber,
from: TWILIO_PHONE_NUMBER,
statusCallback: 'http://postb.in/b/XXXXXXXX'
})
.then((message) => {
console.log(message.sid);
return message.sid;
})
};
Here is a test where I call message sending after initialization:
const { expect } = require('chai');
const smsUtility = require('utils/sms');
describe('Sms utility', () => {
it('should send a message and return message sid', (done) => {
const body = 'Body';
const number = '+XXXXXXXXXXX';
smsUtility.send(body, number)
.then((messageSid) => {
expect(typeof messageSid).to.equal('string');
return done();
})
.catch((err) => {
console.log(err);
return done();
});
});
});
I use test credentials, but when I replace it with real twilio credentials, I successfully receive a message, so this part works fine. Also, when I try to ping postb.in url manually (with curl), it also works OK. Only statusCallback doesn't work.
Thanks.

It looks to me like you have everything set up nicely aside from your Postbin URL.
I noticed you show your URL as http://postb.in/b/XXXXXXXX. But the /b/ version of the URL is the dashboard for your Postbin. Requests to the dashboard won't show up on the dashboard.
Instead, you should use the URL that looks like: http://postb.in/XXXXXXXX. Try that and let me know if it's working.
