How to send sms from Perl

The most simple way to send SMS from Perl 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.

Perl code to send sms to mobile

The Perl sms code sample below demonstrates how you can send SMS using the http rest sms api of Ozeki SMS Gateawy using the Perl 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.
use Ozeki::Libs::Rest::Configuration;
use Ozeki::Libs::Rest::MessageApi;
use Ozeki::Libs::Rest::Message;

my $configuration = new Ozeki::Libs::Rest::Configuration();
$configuration->{ Username } = "http_user";
$configuration->{ Password } = "qwe123";
$configuration->{ ApiUrl } = "";

my $msg = new Ozeki::Libs::Rest::Message();
$msg->{ ToAddress } = "+36201111111";
$msg->{ Text } = "Hello world!";

my $api = new Ozeki::Libs::Rest::MessageApi($configuration);

my $result = $api->Send($msg);


How to use the Perl sms example:

This Perl sms example can be used in any Perl application. To use it, you must add the Ozeki.Libs.Rest library to your project. After the library is added, you must put the using Ozeki.Libs.Rest; directive into the header section of your Perl 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.

How to send SMS from Perl (Simple guidelines)

To send SMS from Perl:

  1. Install a HTTP API user
  2. Enable Log communication events on the Advanced tab
  3. Download then extract the file
  4. Open the file in any text editor
  5. Launch Ozeki SMS Gateway app
  6. Run Perl code in the command prompt
  7. 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 Perl, first you need to install Ozeki SMS Gateway. The SMS gateway can be installed on the same computer, where you develop your Perl code in Windows Notepad or Visual studio Code. 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 Perl code.

HTTP API url to use send sms from Perl

To send SMS from Perl, your Perl will will have to issue an HTTP request to the SMS gateway. The API url is shown below. Note that the IP address ( should be replaced to the IP address of your SMS gateway. If Ozeki SMS Gateway is installed on the same computer where the Perl sms application is running, this can be If it is installed on a different computer it should be the IP address of that computer.

HTTP authentication to use send sms from Perl

To authenticate the Perl 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 Perl you can use the following code to do this encoding:

my ($self, $Username, $Password) = @_;
my $Username_Password = "${Username}:${Password}";
my $Username_Password_encoded = encode_base64($Username_Password);
return "Basic ${Username_Password_encoded}";

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 Perl

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 Perl

To submit the SMS, your Perl application will send an HTTP request similar to the one below. Note, that this requst contains a HTTP header part and a http body part. The HTTP body is a JSON encoded data string. It contains the recipient number and the messages text.

POST /api?action=sendmsg HTTP/1.1
Connection: TE, close
Content-Length: 341
Content-Type: application/json; charset=utf8
Authorization: Basic aHR0cF91c2VyOnF3ZTEyMw==

HTTP response received by the Perl 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 messages submission.

HTTP/1.1 200 OK
User-Agent: OZEKI 10.3.123 (

Connect your SMS gateway to the mobile network and create an HTTP API user account

We assume, you have already installed Ozeki SMS Gateway, and you have connected it to the mobile network. In order to be able to send SMS to a mobile phone from Perl, you need to setup an HTTP API user account in Ozeki SMS Gateway. In this video, we are going to explain to you the process of creating a new HTTP API user account. The video will start with opening the Ozeki SMS gateway application and will take you to have the created HTTP API user. In the process, you will learn how to configure a new user and how to turn on the logging option. The video is only 30 seconds long and it explains the process in a very detailed way. You will have no problem understanding the steps.

How to check that the SMS has been accepted by the HTTP user

After the SMS has been submitted, it is a good idea to check your SMS gateway, to see what it has received. You can check the log by opening the HTTP user's details from the Ozeki SMS Gateway managment console. The following video shows you what to look for.

How to check that the SMS has been sent to the mobile network

The final step in verifying the procedure is to take a look at the logs of the mobile network connection. You might have to turn on logging in the configuration of the connection before you send the message to see the logs. If logging is enabled you will see the phone number and the text of the message you have sent.
