How to send multiple sms from Node.js
The simple way to send SMS from Node.Js is to use the built in HTTP/Rest SMS api of Ozeki SMS Gateway. When you use this API, you will send SMS messages by issuing a HTTP Post request to the SMS gateway. The HTTP Post request will contain a message formatted in json format. The SMS gateway will send this SMS to the recipient phone, and it will return a HTTP 200 OK response to your request.
JavaScript code to send sms to mobile
The JavaScript sms code sample below demonstrates how you can send SMS using the http rest sms api of Ozeki SMS Gateway using the JavaScript Ozeki.Libs.Rest library. This library is provided to you free of charge, and you may use it and modify it in any of your projects.
SendMultipleSms.mjs
import { Configuration, Message, MessageApi } from './Ozeki.Libs.Rest.js';
var configuration = new Configuration();
configuration.Username = "http_user";
configuration.Password = "qwe123";
configuration.ApiUrl = "http://127.0.0.1:9509/api";
var msg1 = new Message();
msg1.ToAddress = "+36201111111";
msg1.Text = "Hello world 1";
var msg2 = new Message();
msg2.ToAddress = "+36202222222";
msg2.Text = "Hello world 2";
var msg3 = new Message();
msg3.ToAddress = "+36203333333";
msg3.Text = "Hello world 3";
var messages = new Array();
messages.push(msg1);
messages.push(msg2);
messages.push(msg3);
var api = new MessageApi(configuration);
const result = await api.Send(messages);
console.log(result.toString());
How to use the JavaScript sms example:
You can use the Message class to create the SMS and you can use the MessageApi class to send the SMS to the SMS gateway. The SMS gateway will forward your message to the mobile network either through a wireless connection or through the Internet.

How to send SMS from Node.Js (Quick steps)
To send sms from Node.Js:
- Install Ozeki SMS Gateway
- Connect Ozeki SMS Gateway to the mobile network
- Send a test sms from Ozeki GUI
- Create a HTTP sms api user
- Apache NetBeans
- Download the example project above
- Create the SMS by creating a new Message object
- Create an api to send your message
- Use the Send method to send your message
- Read the response message on the console
- Check the logs in the SMS gateway
Install Ozeki SMS Gateway and create an HTTP API user
To be able to send SMS from Node.Js, first you need to install Ozeki SMS Gateway. The SMS gateway can be installed on the same computer, where you develop your JavaScript code in Visual Studio Code or any other code editor. After installation, the next step is to connect Ozeki SMS Gateway to the mobile network. You can send a test sms from the Ozeki GUI to verify, that your mobile network connection works. The final step to prepare your environment is to create a HTTP sms api user. Create a user with a username of "http_user", and with a password of "qwe123" to make the example work without modification.
After the environment is setup, you can run your JavaScript code.
HTTP API url to use send sms from Node.Js
To send SMS from Node.Js, your JavaScript will have to issue an HTTP request to the SMS gateway. The API url is shown below. Note that the IP address (127.0.0.1) should be replaced to the IP address of your SMS gateway. If Ozeki SMS Gateway is installed on the same computer where the JavaScript sms application is running, this can be 127.0.0.1. If it is installed on a different computer, it should be the IP address of that computer.
http://127.0.0.1:9509/api?action=rest
HTTP authentication to use send sms from JavaScript
To authenticate the Node.Js sms client, you need to send the username and password in a base64 encoded string to the server in a HTTP request. The format used is: base64(username+":"+password). In JavaScript you can use the following code to do this encoding:
var usernamePassword = username + ":" + password;
return `Basic ${Base64.encode(usernamePassword)}`;
For example, if you encode the username 'http_user' and the password 'qwe123', you will get the following base64 encoded string: aHR0cF91c2VyOnF3ZTEyMw==. To send
HTTP request header to send SMS from JavaScript
To send the SMS messages, you need to include the following lines as headers in the HTTP request. Note that we include a content type and an Authorization header.
Content-Type: application/json Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
HTTP request to send SMS from Node.Js
To submit the SMS, your Node.Js application will send an HTTP request similar to the one below. Note, that this request contains a HTTP header part and a http body part. The HTTP body is a JSON encoded data string. It contains the recipient's number and the message's text.
POST /api?action=sendmsg HTTP/1.1
Connection: close
Content-Length: 932
Content-Type: application/json
Accept: */*
Accept-Encoding: gzip,deflate
Authorization: Basic aHR0cF91c2VyOnF3ZTEyMw==

HTTP response received by the JavaScript sms example
Once the SMS gateway receives this request, it will generate a HTTP response. The HTTP response will contain a status code, to indicate whether the SMS submit request was successful or not. It will also return a JSON encoded structure to provide you useful details about the message's submission.
HTTP/1.1 200 OK
