How to Delete an SMS in Javascript

The simplest way to delete SMS from JavaScript is to use the built in HTTP/Rest SMS api of Ozeki SMS Gateway. When you use this API, you will delete SMS messages by issuing a HTTP POST request to the SMS gateway. The HTTP POST request will return a HTTP 200 OK response to your request, and the id(s) of the message(s) which has been deleted.

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, 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.

  1. Install a HTTP API user
  2. Enable Log communication events on the Advanced tab
  3. Setup WampServer
  4. Download then extract the DeleteSms.js.zip file
  5. Put the contents of the zip file into the \www\ folder of the wampserver: C:\wamp64\www

  8. After you have opened the website, you can send an SMS by clicking on the DownloadIncoming button
  9. Check the logs to see if the SMS sent

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 delete 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 delete 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 delete 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 body part. The body part contains the folder which contains our message(s), and the id(s) of the message(s) in JSON string. 

POST /api?action=deletemsg HTTP/1.1
Connection: Keep-Alive
Content-Length: 73
Content-Type: application/json
Authorization: Basic aHR0cF91c2VyOnF3ZTEyMw==
Host: 127.0.0.1:9509
  
{
    "folder":  "inbox",
    "message_ids": [
        "3a922414-458f-4866-a8ee-f053d1132a6b"
    ]
}

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
User-Agent: OZEKI 10.3.116 (www.myozeki.com)
Content-Type: application/json; charset=utf8
Last-Modified: Mon, 07 Jun 2021 14:10:25 GMT
Server: 10/10.3.116
Transfer-Encoding: chunked
{
    "http_code": 200,
    "response_code": "SUCCESS",
    "response_msg": "",
    "data": {
        "folder": "inbox",
        "message_ids": [
            "3a922414-458f-4866-a8ee-f053d1132a6b"
        ]
