4 Different Ways To Send Text Messages (SMS) with Node.js

SMS notifications are widely used in modern web and mobile applications. Applications can engage with clients effectively and programmatically to facilitate fundamental user interactions in your app, such as two-factor authentication, password resets, user phone number verification, etc.

You can use an SMS API to enable SMS notifications in your applications. There are multiple options available, and this article will discuss four different ways of sending SMSs with Node.js to help you decide which option is best for your needs.

1. Using Twilio API

Twilio's Programmable SMS API allows you to integrate powerful messaging capabilities into your apps with Node.js. You can send and receive SMS messages, track their delivery, schedule SMS messages to transmit at a later time, and access and edit message history using this REST API.

As prerequisites to use Twilio with Node.js, you will need :

  • A Twilio account, either free or paid.
  • Node.js installed on your machine
  • SMS-enabled phone number (you can search for and buy one in the Twilio console).

Twilio uses webhooks to notify your app when events like receiving an SMS message occur. Twilio sends an HTTP request (typically a POST or a GET) to the URL you specified for the webhook when an event happens. The event's information, such as the incoming phone number or the body of an incoming message, will be included in Twilio's request. Some webhooks are just informative, while others expect your web app to respond. You must notify Twilio API to which URL these webhooks are sent in all of these cases.

Advantages of using Twilio SMS API

  1. Support of multiple programming languages.
  2. On-demand billing.
  3. Good documentation and community support.

Disadvantages of using Twilio SMS API

  1. Not mobile-friendly
  2. Expensive compared to other APIs.
  3. Hard to get started without a software development background.

Tutorial: How to send SMS using Twilio SMS API

The following is the base for all URLs in the Twilio documentation.

1 https://api.twilio.com/2010-04-01

Sending a text message with the Twilio API is straightforward, requiring ten lines of code roughly.

Twilio simplifies the process by providing a helper library. To begin, use npm to install the twilio-node library from the terminal.

1 npm install twilio

Next, create a file (sms.js) and open it in the text editor. Load the twilio-node helper library at the top of the file and use it to create a Twilio REST client. Dotenv is then used to populate your environment variables with your account credentials. You can find the credentials you need for this step in the Twilio Console.

1 2 3 4 5 const twilio = require('twilio'); require('dotenv').config(); const accountSid = process.env.TWILIO_ACCOUNT_SID; const authToken = process.env.TWILIO_AUTH_TOKEN;

Then all you have to do is start a new Twilio client instance and send an SMS from your Twilio phone number to your phone number. Ensure the phone numbers are replaced with your Twilio and cell phone numbers.

1 2 3 4 5 client.messages.create({ from: process.env.TWILIO_PHONE_NUMBER, to: process.env.CELL_PHONE_NUMBER, body: "Send SMS using Twilio Api in Node.js!" }).then((message) => console.log(message.sid));

Then, by running the following command in the terminal, you can receive the SMS in seconds.

1 run sms.js

Likewise, you can now successfully send some messages with the Twilio Programmable SMS API and the Node.js helper library.

2.Using MessageBird API

MessageBird provides a variety of SMS delivery options. You can, for example, send SMS via email or an API connection. In addition, users can always check the status of their messages because each one is assigned with a unique random ID, allowing users always to check the status.

The SMS API has an HTTP, a RESTful endpoint structure, and an access key for API authorization. The request and response payloads are formatted as JSON with UTF-8 encoding and URL encoded values.

As prerequisites, you should have:

  • NodeJS development environment.
  • Project directory with the MessageBird SDK (This helper library helps interactions between your Node.js application's code and the MessageBird API)
  • MessageBird Account.

Advantages of using MessageBird API

  • User-friendly dashboard with features like flow builder.
  • Cost-effective pricing.
  • Can be easily integrated with native apps.

Disadvantages of using MessageBird API

  • Deliverability problems with some phone numbers.
  • Lack of plugins.

Tutorial: How to send SMS using MessageBird API

The base URL for all URLs in MessageBird's SMS API documentation is as follows.

1 https://rest.messagebird.com/messages

Create a file (sms.js) and open it in a text editor as the next step. Then, using require, you can include the MessageBird SDK ().

1 var messagebird = require('messagebird')('YOUR-API-KEY');

The SDK only accepts one argument, which is your API key. The string YOUR-API-KEY can then be replaced.

Then you can create a new instance of the MessageBird client via messages.create()and feed it to the originator (the sender), receivers (the phone numbers who will receive the message), and body (the message's content). You can use the number you purchased as the originator. The message's body will be limited to 160 characters; otherwise, it will be divided into many pieces. Make sure to replace the values in the sample code with actual data when testing.

1 2 3 4 5 messagebird.messages.create({ originator : '31970XXXXXXX', recipients : [ '31970YYYYYYY' ], body : 'Hello World, I am a text message and I was hatched by Javascript code!' }

If everything goes properly, you'll get a response; if something goes wrong, you'll get an error response. As shown below, a callback function is used to manage this.

1 2 3 4 5 6 7 8 9 function (err, response) { if (err) { console.log("ERROR:"); console.log(err); } else { console.log("SUCCESS:"); console.log(response); } });

3. Using Plivo API

Plivo API makes it easier to integrate communications into your code by allowing you to send messages to any phone number using HTTP verbs and standard HTTP status codes. Other use cases include sending alerts and receiving delivery status updates.

Advantages of using Vonage SMS API

  1. Anyone can easily get started.
  2. User-friendly UI/UX.
  3. Seamless customization.

Disadvantages of using Vonage SMS API

  1. Documentation is a bit challenging to understand.
  2. Lack of error messages.

Tutorial: How to send SMS using Vonage SMS API

1 https://api.plivo.com/{version}/

Prerequisites for Plivo are:

  • Plivo account.
  • Plivo phone number
  • NodeJS development environment.
  • Plivo's Node SDK.

To begin, create a new js file (sms.js) and use npm to install Express and the Plivo Node.js SDK.

1 $ npm install express plivo

Then you can create a new instance of the Plivo client via messages.create() and feed it the src(the sender id ), dst (the phone numbers who will receive the message), and text (the content of the message).

You can use the Plivo console to replace the auth placeholders with your authentication credentials. Actual phone numbers should be substituted for the placeholders (src and dst). Make sure that it's in E.164 format.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 var plivo = require('plivo'); (function main() { 'use strict'; var client = new plivo.Client("<auth_id>", "<auth_token>"); client.messages.create( { src: "<sender_id>", dst: "<destination_number>", text: "Hello, from Node.js!", } ).then(function (response) { console.log(response); }); })();

Keeping your credentials in the auth id and auth token environment variables will be much safer. It will allow you to start the client with no arguments, and Plivo will automatically fetch the information from the environment variables.

Finally, save and execute the program to see if you received an SMS on your phone.

1 $ node SMS.js

You can also keep track of the status of your outbound messages with Plivo. First, you have to send a request to the server endpoint specifying its URL and HTTP method to set up a server endpoint. Then Plivo will call this endpoint with the latest message details as and when the message status changes.

4. Using Multi-Channel Notification API

Apart from the methods mentioned above, you can use a multi-channel notification service like Courier to send SMS, which helps you reach your customers on more than one channel using a uniform API.

With the modern application requirements, using a multi-channel notification service like Courier can streamline your notification flow by creating all the relevant channels with them a single API.

Advantages of using a Multichannel Notification Service

  • You can notify users across different notification channels using a single API.
  • You won't have to manage a large codebase since all channels use the same API.
  • You can add more notification channels without modifying your code.
  • As a result, your notification service can be managed by any non-technical user.

Disadvantages of using a Multichannel Notification Service

  • Consuming many notification channels can be costly.
  • The maximum number of notifications you can receive per month limits you.

Tutorial: How to send SMS using a Multichannel Notification Services

For this demonstration, I will be using Courier since it supports some well-known SMS providers like Twillio, Plivo, MessageBird, etc.

Creating a Courier account

You can easily create a free Courier account using the following link - https://app.courier.com/signup.

Creating a New Channel

After login into the account, you need to create a new channel. For that, select the Channels tab from the Courier dashboard. You will see a list of SMS providers there, and you can select one from the list. For this example, I have selected MessageBird.

MessageBird Send SMS

Then, you will be asked to enter an Originating Number and an Access Key. After that, click the Install Provider button.

Creating a Notification

After creating the channel, select the Designer tab from the Courier dashboard and click the Create Notification button. There, select SMS as the channel and MessageBird as the provider.

Send SMS Notification

Then, click the Publish Changes button and move to the Preview tab. There, click the Create Test Event button to create a new event.

Send TXT Message Node.js

Install Courier SDK

After creating the event, you can find the auto-generated code to configure Courier with your project in the Send tab.

Then, you need to install Courier SDK using the npm install @trycourier/courier command and copy the auto-generated code to your project.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 import { CourierClient } from "@trycourier/courier"; const courier = CourierClient({ authorizationToken: "pk_prod_Y2Y3BK4MAM40YTN029MVR64YFKR0" }); const { requestId } = await courier.send({ message: { to: { phone_number: "5558675309", }, template: "NEDRQK62TWM70MHT84S6FKSXM4VT", data: { test: "test", }, }, });

Note: You can customize the above code based on your requirements. Please refer to Courier documentation for more details.
