How to send SMS masive in Twilio with Nodejs?

Question

I would like to know how I can send a message to different numbers. I mean, send SMS as notifications to different numbers in the same String Array. Something like:

body: "Hello Word!"
number:["+2222", "+2222", "+2222"]

Is it possible to do this with twilio?

It should be possible, if it is possible with mail, how is it done with telephone numbers?

I am using nodeJs and had something like:

updated code

    const sendBulkMessages = async(req, res) => {
    let messageBody = req.body;
    let numberList = req.body;
    var numbers = [];
    for (i = 0; i < numberList.length; i++) {
        numbers.push(JSON.stringify({
            binding_type: 'sms',
            address: numberList[i]
        }))
    }


    const notificationOpts = {
        toBinding: numbers,
        body: messageBody,
    };

    const response = await client.notify
        .services(SERVICE_SID)
        .notifications.create(notificationOpts)
        .then(notification => console.log(notification.sid))
        .catch(error => console.log(error));

    console.log(response);

    res.json({
        msg: 'Mensaje enviado correctamente'
    });
}

But it tells me an error that I did not send the body, when clearly I do.

Someone could help me? Please

It looks like you are trying to send these messages via a post request to an Express application. The issue is that you are not extracting the data from the body of the request correctly.

If your POST request body is a JSON object that looks like this:

{
  "toBinding": ['+222', '+222'],
  "body": 'Hello'
}

Then you will need to make sure you are parsing the body of the request as JSON, normally by adding the Express body parser JSON middleware , and then extract the data from the request body like this:

let messageBody = req.body.body;
let numberList = req.body.toBinding;

Here's the full script:

const sendBulkMessages = async(req, res) => {
    let messageBody = req.body.body;
    let numberList = req.body.toBinding;
    var numbers = [];
    for (i = 0; i < numberList.length; i++) {
        numbers.push(JSON.stringify({
            binding_type: 'sms',
            address: numberList[i]
        }))
    }


    const notificationOpts = {
        toBinding: numbers,
        body: messageBody,
    };

    const response = await client.notify
        .services(SERVICE_SID)
        .notifications.create(notificationOpts)
        .then(notification => console.log(notification.sid))
        .catch(error => console.log(error));

    console.log(response);

    res.json({
        msg: 'Mensaje enviado correctamente'
    });
}

Having inspected your repo , it appears that your function was actually correct, but the way you were exporting and requiring functions wasn't.

You can't export functions like this:

 module.exports = sendMessage, sendMessageWhatsapp, sendBulkMessages;

That only exports the first function, the others are ignored. So I updated it to this:

module.exports = { sendMessage, sendMessageWhatsapp, sendBulkMessages };

This exports an object containing the three functions. Then, when you require the functions, you can't do this:

const sendMessage = require('./message');
const sendMessageWhatsapp = require('./message');
const sendBulkMessages = require('./message');

That requires the same function three times. With the update above, you can now do this:

const {
  sendMessage,
  sendBulkMessages,
  sendMessageWhatsapp,
} = require("./message");
