How to send multiple sms from R
The simplest way to send multiple SMS from R 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's phone, and it will return a HTTP 200 OK response to your request.
R code to send multiple sms messages to mobile
The R sms code sample below demonstrates how you can send SMS using the http rest sms api of Ozeki SMS Gateway using the R 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.Rlibrary(Ozeki.Libs.Rest) configuration <- Ozeki.Libs.Rest::Configuration$new( username = "http_user", password = "qwe123", api_url = "http://127.0.0.1:9509/api" ) msg1 <- Ozeki.Libs.Rest::Message$new() msg1$to_address <- "+36201111111" msg1$text <- "Hello world 1" msg2 <- Ozeki.Libs.Rest::Message$new() msg2$to_address <- "+36202222222" msg2$text <- "Hello world 2" msg3 <- Ozeki.Libs.Rest::Message$new() msg3$to_address <- "+36203333333" msg3$text <- "Hello world 3" api <- Ozeki.Libs.Rest::MessageApi$new(configuration) result <- api$send(list(msg1, msg2, msg3)) print(result$to_string())
How to use the R sms example:
This R sms example can be used in any R application. To use it, you must download the Ozeki.Libs.Rest library. After the library is downloaded, you need to add a reference to it in your R 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 R (Simple guidelines)
To send SMS from R:
- Install a HTTP API user
- Enable Log communication events on the Advanced tab
- Setup Visual Studio
- Download then extract the SendMultipleSms.R.zip file
- Launch Ozeki SMS Gateway app
- Run SendMultipleSms.R R code using the command prompt
- 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 R, first you need to install Ozeki SMS Gateway. The SMS gateway can be installed on the same computer, where you develop your R code in any text editor, such as windows notepad. 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 R code.
HTTP API url to use send sms from R
To send SMS from R, your R 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 R 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 R
To authenticate the R 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 R you can use the following code to do this encoding:
username_password <- paste(username, ":", password, sep="")
username_password_encoded <- base64enc::base64encode(charToRaw(username_password))
return (paste("Basic", username_password_encoded, sep=" "))
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 R
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 R
To submit the SMS, your R 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 numbers and the texts for the message's we sent.
POST /api?action=sendmsg HTTP/1.1
Content-Length: 962
Content-Type: application/json
Accept: application/json
Accept-Encoding: deflate, gzip
Authorization: Basic aHR0cF91c2VyOnF3ZTEyMw==

HTTP response received by the R 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
