Presequence

Getting API access

Namecheap has certain requirements for activation to prevent system abuse. In order to have API enabled for your account, you should meet one of the following requirements:

• have at least 20 domains under your account;
• have at least $50 on your account balance;
• have at least $50 spent within the last 2 years.

Credentials

Use of this plugin requires a configuration file containing Namecheap API credentials, obtained from your Namecheap account's API Managenment page.

# Namecheap API credentials used by Certbot
dns_namecheap_username=my-username
dns_namecheap_api_key=my-api-key

The path to this file can be provided by using the --dns-namecheap-credentials command-line argument.

Important

• Not recommended usage If you know what you're doing install the plugin into the same python environment like certbot.

• Recommended usage work in isolated enviroment use this routine by creating speacial command as I will show in steps:

• install virtual modules

sudo apt install python3-venv python3-pip

• start virtual env and install the package

python3 -m venv ~/certbot-venv
source ~/certbot-venv/bin/activate
pip install .

• Check that certbot discovers the plugin:

certbot plugins

you must see the package name certbot-dns-namecheap in the list

• Now run the command:

certbot certonly \
  -a dns-namecheap \
  --dns-namecheap-credentials=/namecheap.ini \
  --agree-tos \
  -email "[email protected]" \
  -d example.com \
  --test-cert

if it works that mean you had success installing and use

• Deactivate the virtual environment

deactivate

• creat auto use for the virtual enviroment

nano /usr/local/bin/certbot-namecheap

#bash
#!/bin/bash
# Activate the virtual environment
source /path/to/certbot-venv/bin/activate

# Run Certbot with all arguments passed to the script
