How to send sms from Javascript
The simplest way to send SMS from JavaScript 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.

How to use the JavaScript sms example:
This JavaScript sms example can be used in any web application. To use it, you must add the Ozeki.Libs.Rest.js to your project. After it is added to your project, you must put the import {MessageApi, Message, Configuration} from './Ozeki.Libs.Rest.js'; directive into the header section of your JavaScript source code. This will allow you to use the classes provided by the Ozeki.Libs.Rest library. You can use the Message class to create the SMS. 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.

Install Ozeki SMS Gateway and create an HTTP API user
To be able to send SMS from JavaScript, 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. 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 JavaScript
To send SMS from JavaScript, 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 JavaScript 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:
// You can find the Base64 encoder in the Ozeki.Libs.Rest.js file
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 JavaScript
To submit the SMS, your JavaScript 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: 418
Content-Type: text/plain;charset=UTF-8

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.
