IP address block/unblock via Cloudflare’
Cloudflare has upgraded their API to version 4 some while ago. https://api.cloudflare.com/#user-level-firewall-access-rule-properties I want to use the new APIs to block IP addresses using fail2ban. Using curl directly is a bit cumbersome, so I created a few php helper scripts. They can also be used in other projects.
