Twilio integration with React Native and Node.js backend

Updated: Feb 9, 2023


In today’s world, voice calling is becoming increasingly popular, and it is becoming increasingly important for businesses to incorporate voice calling into their products. Twilio is a popular cloud-based voice-calling service that allows developers to easily add voice-calling capabilities to their applications. In this article, we’ll look at how to integrate Twilio Voice Call Service with a Node.js backend and a React Native mobile app.


To get started, you’ll need to create a Twilio account and obtain your account credentials. Once you have your credentials, you’ll need to install the Twilio Node.js SDK. This SDK will allow you to interact with the Twilio API and make voice calls.


Once the SDK is installed, you’ll need to set up a Node.js server. This server will act as the backend for your application and will be responsible for making requests to the Twilio API. You can use any web framework, such as Express or Koa.


Once your server is set up, you’ll need to create an endpoint that will handle incoming requests from your React Native mobile app. This endpoint will take the phone number of the person you want to call and use the Twilio SDK to make the call. Here’s an example of how this endpoint might look:


// Handle incoming request from React Native app

app.post('/make-call', (req, res) => {

// Get the phone number from the request

const phoneNumber = req.body.phoneNumber;

// Use the Twilio SDK to make the call

twilioClient.calls.create({ URL: 'http://myapp.com/call-handler', to: phoneNumber, from: TWILIO_NUMBER }) .then(call => console.log(call.sid)) .catch(err => console.log(err)); });


The above code uses the Twilio SDK to call the specified phone number. The “url” parameter is a URL that points to a handler that will receive events related to the call (e.g. when the call is answered, when it ends, etc.).


Once you have your endpoint set up, you’ll need to create a React Native mobile app allowing users to make voice calls. This app will need to make a request to the endpoint you created in the previous step, passing in the phone number of the person they want to call. Here’s an example of how this might look:


// Make a request to the `/make-call` endpoint

const response = await fetch('http://myapp.com/make-call', { method: 'POST', body: JSON.stringify({ phoneNumber: '+15555555555' }) });


Once the request is sent, the backend will make the call using the Twilio SDK. The user will then be able to hear the call and be able to answer it or hang up.


Integrating Twilio Voice Call Service with a Node.js backend and a React Native mobile app is relatively straightforward. By following the steps outlined in this article, you should be able to easily add voice-calling capabilities to your application.
