A Cloudflare wrapper to bulk add / edit your WAF custom rules using Cloudflare's API.

This library is a wrapper that aims to easily create, modify, delete security rules. It also provides a way to import & export new rules in your domain's firewall.

If you have several rules that you want to duplicate among your domains, this package is made for you!

Cloudflare's Security Rules are available in a domain in the Security > Security Rules tab, by default, you have a free plan with 5 custom rules available.

The official documentation is available here: https://developers.cloudflare.com/waf/custom-rules/

Domain Security Rules

📥 Installation

pip install cf_rules

# OR

git clone https://github.com/QuentiumYT/Cloudflare-Firewall-Rules.git
cd Cloudflare-Firewall-Rules/
pip install .

🚀 Usage

You have 2 auth methods available:

A Global API Key or a specific API Token generated from here: https://dash.cloudflare.com/profile/api-tokens

Cloudflare Global API Key

Cloudflare Key

Using a Global API Key, you will have access to everything allowed by a Cloudflare account. It can access all domains from every account you have, this might be overpowered...

Cloudflare API Token

An API token is recommended to keep control of specific domains only. You will need to give the correct permissions for Cloudflare's WAF Custom rules to work.

The required permissions are "Zone.Zone, Zone.Firewall Services"

Cloudflare Token

Here is a token creation example:

Cloudflare Token

💨 Quickstart

You can use any example scripts in the examples folder, just create a .env file

I might add more examples in the future, but everything is in the docs :)


Create any Python file in the cloned directory and paste these lines

from cf_rules import Cloudflare

cf = Cloudflare()
cf.auth_key("<your-address@email.com>", "<your-global-api-key>")
# OR
cf.auth_token("<your-specific-bearer-token>")

domains = cf.domains[0].name

print(domains)
# >>> ['example.com']

cf.export_rules("example.com")
# Creates a text file for every rule you have on your domain

cf.create_rule("example.com", "My Bad Bots FW rule", "Bad Bots", "challenge")
# Create a new rule with the content of the "Bad bots.txt" file with the challenge action

cf.update_rule("example.com", "My Bad Bots FW rule", "Bad Bots lib")
# Change the rule's expression to the content of the "Bad bots lib.txt" file
