Export all CloudFlare DNS Zone IDs and Domain names in a CSV

#!/bin/bash

# Set CloudFlare API credentials
CF_API_EMAIL="YOUR_CLOUDFLARE_EMAIL"
CF_API_KEY="YOUR_CLOUDFLARE_API_KEY"

# Set output file name
OUTPUT_FILE="cloudflare_dns_zones.csv"

# Get all DNS zones for the account
DNS_ZONES=$(curl -s -X GET "https://api.cloudflare.com/client/v4/zones" \
     -H "X-Auth-Email: ${CF_API_EMAIL}" \
     -H "X-Auth-Key: ${CF_API_KEY}" \
     -H "Content-Type: application/json")

# Extract zone ID and domain name and write to output file
echo "Zone ID,Domain" > "${OUTPUT_FILE}"
for row in $(echo "${DNS_ZONES}" | jq -r '.result[] | @base64'); do
    zone_id=$(echo ${row} | base64 --decode | jq -r '.id')
    domain=$(echo ${row} | base64 --decode | jq -r '.name')
    echo "${zone_id},${domain}" >> "${OUTPUT_FILE}"
done

echo "All DNS zones have been exported to ${OUTPUT_FILE}."

Make sure you have jq installed. To use this script, replace the YOUR_CLOUDFLARE_EMAIL and YOUR_CLOUDFLARE_API_KEY with your actual API credentials, and specify the output file name in the OUTPUT_FILE variable.

Save the script in a file with a .sh extension (e.g. export_cloudflare_dns_zones.sh), make it executable (chmod +x export_cloudflare_dns_zones.sh), and run it using ./export_cloudflare_dns_zones.sh.

The script will create a CSV file with the zone ID and domain name for each DNS zone in your CloudFlare account. The file will be saved in the same directory as the script.
