How to Delete an SMS in Ruby

The most simple way to delete SMS messages from Ruby 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 delete an SMS using Ruby (Quick steps)

To delete an SMS using Ruby:

  1. Download the DeleteSms.rb.zip file
  2. Extract the .zip file from Downloads folder
  3. Open the DeleteSms.rb file in any text editor like Windows Notepad
  4. Launch Ozeki SMS Gateway
  5. Create a HTTP API user in Ozeki
  6. Run DeleteSms.rb Ruby code using the command prompt
  7. Check the Sent box in Ozeki SMS Gateway

Install Ozeki SMS Gateway and create an HTTP API user

To be able to send SMS from Ruby, first you need to install Ozeki SMS Gateway. The SMS gateway can be installed on the same computer, where you develop your Ruby 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 Ruby code.

HTTP API url to use send sms from Ruby

To send SMS from Ruby, your Ruby will 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 Ruby 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 Ruby

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

username_password = username + ':' + password
username_password_encoded = Base64.encode64(username_password)
'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 Ruby

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 Ruby

To delete a message, your Ruby application will send an HTTP request similar to the one below. Note, that this requst contains a HTTP header part and a body part. The body part contains the json encoded sms ids. 

POST /api?action=deletemsg HTTP/1.1
Content-Length: 73
Content-Type: application/json
Accept: application/json
Accept-Encoding: gzip;q=1.0,deflate;q=0.6,identity;q=0.3
Authorization: Basic aHR0cF91c2VyOnF3ZTEyMw==
Host: 127.0.0.1:9509
User-Agent: Faraday v1.5.0

{	
	"folder":	"inbox",
	"message_ids":	[
		"8ddff323-a0e1-474f-b4b1-58d7fed30009"
	]
}

HTTP response received by the Ruby 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. 

User-Agent: OZEKI 10.3.123 (www.myozeki.com)
Content-Type: application/json; charset=utf8
Last-Modified: Tue, 06 Jul 2021 15:58:36 GMT
Server: 10/10.3.123
Transfer-Encoding: chunked

{
	"http_code": 200,
	"response_code": "SUCCESS",
	"response_msg": "",
	"data": {
	  "folder": "inbox",
	  "message_ids": [
	    "8ddff323-a0e1-474f-b4b1-58d7fed30009"
	  ]
	}
}
