How to Delete an SMS in Python

The simplest way to delete SMS from Python 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 contain the ids of the messages we want to delete, formatted in JSON format. The SMS gateway will return the ids of the messages which have been successfully deleted, and it will also return with an HTTP 200 OK response to your request.

Python code to delete sms

The Python sms code sample below demonstrates how you can delete SMS using the http rest sms api of Ozeki SMS Gateway using the Python ozekilibsrest library. This library is provided to you free of charge, and you may use it and modify it in any of your projects.

DeleteSms.py

		from ozekilibsrest import Configuration, Message, MessageApi, Folder
		
		configuration = Configuration(
		    username="http_user",
		    password="qwe123",
		    api_url="http://127.0.0.1:9509/api"
		)
		
		msg = Message(
		    message_id="e2259da4-e806-4ce2-b02b-e47905772625"
		)
		
		api = MessageApi(configuration)
		
		result = api.delete(Folder.Inbox, msg)
		
		print(result)
	

How to use the Python sms example:

This Python sms example can be used in any Python application. To use it, you must install the ozekilibsrest package with the pip install ozekilibsrest command. After the package is installed, you must put the from ozekilibsrest import Configuration, Message, MessageApi directive into the header section of your Python source code. This will allow you to use the classes provided by the ozekilibsrest 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 delete sms from Python (Quick steps)

To delete sms from Python:

1. Download and install Python
2. Install the ozekilibsrest library using pip or codna
3. Download the DeleteSms.py.zip file
4. Extract the .zip file from Downloads folder
5. Open the DeleteSms.py file in any text editor
6. Launch Ozeki SMS Gateway
7. Create a HTTP API user in Ozeki
8. Run DeleteSms.py code using the command prompt to send the test SMS messages
9. 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 Python, first you need to install Ozeki SMS Gateway. The SMS gateway can be installed on the same computer, where you develop your Python 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 Python code.

HTTP API url to use send sms from Python

To send SMS from Python, your Python 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 Python 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 Python

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

	    def create_authorization_header(username, password):
	        username_password = f'{ username }:{ password }'
	        return f'Basic { b64encode(username_password.encode()).decode() }'
	

For example, if you encode the username 'http_user' and the password 'qwe123', you will get the following base64 encoded string: aHR0cF91c2VyOnF3ZTEyMw==.

HTTP request header to send SMS from Python

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 Python

To submit the SMS messages, your Python application will send an HTTP request similar to the one below. Note, that this request contains a HTTP header part, and an HTTP body part. The body part contains the ids of the messages we would like to delete.

POST /api?action=deletemsg HTTP/1.1
Host: 127.0.0.1:9509
User-Agent: python-requests/2.26.0
Accept-Encoding: gzip, deflate
Accept: */*
Connection: keep-alive
Authorization: Basic aHR0cF91c2VyOnF3ZTEyMw==
Content-Type: application/json
Content-Length: 76

{
	"folder": "inbox",
	"message_ids": [
		"af5819d4-e32f-4653-a6d4-8fb49017164e"
	]
}
	

HTTP response received by the Python 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
Transfer-Encoding: chunked
Content-Type: application/json; charset=utf8
Last-Modified: Fri, 17 Sep 2021 09:14:01 GMT
Server: 10/10.3.124 Microsoft-HTTPAPI/2.0
User-Agent: OZEKI 10.3.124 (www.myozeki.com)

{
  "http_code": 200,
  "response_code": "SUCCESS",
  "response_msg": "",
  "data": {
    "folder": "inbox",
    "message_ids": [
      "af5819d4-e32f-4653-a6d4-8fb49017164e"
    ]
  }
}
