Automate Cloudflare DNS with Python

Managing DNS records manually can be time-consuming, especially for large-scale applications. Automating this process using Cloudflare's API and Python can save you time and reduce errors. In this tutorial, we’ll walk you through the steps to automate DNS record creation on Cloudflare.

Prerequisites

Before you begin, ensure you have the following:

A Cloudflare account with administrative access
Python 3.x installed on your system
The requests library installed (pip install requests)
Your Cloudflare API token (available in your Cloudflare dashboard)

Step 1: Obtain Your Cloudflare API Token

Log in to your Cloudflare account.
Navigate to My Profile > API Tokens.
Click Create Token and select the template Edit zone DNS.
Specify the zones you want to manage and generate the token.
Save the token securely, as it won’t be displayed again.

Step 2: Install Required Python Libraries

Ensure you have the requests library installed. If not, run:

bash
pip install requests

Step 3: Write the Python Script

Below is a Python script to automate DNS record creation:

python
import requests

## Cloudflare API credentials
api_token = 'YOUR_API_TOKEN'
zone_id = 'YOUR_ZONE_ID'

## DNS record details
record_data = {
    'type': 'A',  # Record type (A, CNAME, etc.)
    'name': 'example.com',  # Record name
    'content': '192.0.2.1',  # Record content (IP address or domain)
    'ttl': 3600,  # Time to live (optional)
    'proxied': False  # Whether to proxy through Cloudflare (optional)
}

## API endpoint
url = f'https://api.cloudflare.com/client/v4/zones/{zone_id}/dns_records'

## Headers
headers = {
    'Authorization': f'Bearer {api_token}',
    'Content-Type': 'application/json'
}

## Send the request
response = requests.post(url, json=record_data, headers=headers)

## Check the response
if response.status_code == 200:
    print('DNS record created successfully!')
    print(response.json())
else:
    print('Failed to create DNS record.')
    print(response.text)

Step 4: Customize the Script

Replace the following placeholders with your actual data:

YOUR_API_TOKEN: Your Cloudflare API token
YOUR_ZONE_ID: Your Cloudflare zone ID (found in the Cloudflare dashboard)
record_data: Adjust the record type, name, content, and other parameters as needed.

Step 5: Run the Script

Save the script as create_dns_record.py and run it using Python:

bash
python create_dns_record.py

Step 6: Verify the DNS Record

Conclusion

Automating DNS record creation on Cloudflare using Python and their API can significantly streamline your workflow. This tutorial provided a step-by-step guide to get you started. You can extend this script to handle multiple records or integrate it into larger automation workflows.

For more advanced use cases, refer to the Cloudflare API documentation.
