Hello. I’m trying to create a custom application for sending SMS from Airtable. Actually there already exist an app like that

but for some reasons I can’t use Twilio service. So I’ve got a code from telecom provider which I’m working with, and this code is working when I run it on my own computer, it sends SMS.

So I wrote the function in my Airtable custom app with this code, but it’s doesn’t work when I trying to call this function

function sendSMS(){

    const https = require('https');



    const data = JSON.stringify({

        auth: {apikey: 'API key'},

        data: {

            message: 'TEST.',

            sender: {text:'TEST'},

            recipients: r{phonenr:'+421XXXXXXXXX'}]

        }

    });



    const options = {

        hostname: 'api-tls12.smstools.sk',

        port: 443,

        path: '/3/send_batch',

        method: 'POST',

        headers: {

            'Content-Type': 'application/json;charset=UTF-8',

            'Content-Length': data.length

        }

    };



    const req = https.request(options, res => {

        console.log(`statusCode: ${res.statusCode}`)

        res.on('data', d => {

            process.stdout.write(d)

            console.error(data)

        })

    });



    req.on('error', error => {console.error(error)});

    req.write(data);

    req.end()

}

What’s wrong with it?
