Stops fake checkout orders, card testing attacks, and spam bots that bypass CAPTCHA. Works instantly with all checkout types.

== Description ==

**Checkout Shield** stops fake checkout orders and card testing attacks — the kind that bypass your CAPTCHA.

Card testing bots don't fill out your checkout form. They hit your store's checkout API directly, completely skipping any reCAPTCHA or hCaptcha you've set up. That's why CAPTCHA alone doesn't stop them.

This plugin verifies that every checkout request comes from a real browser session. Bots that can't prove they loaded your checkout page get blocked before WooCommerce processes the order.

= Why Store Owners Choose This Plugin =

* **Catches what CAPTCHA misses** — blocks bots hitting your checkout API directly
* **Works with any caching** — LiteSpeed, Cloudflare, WP Rocket, W3TC — no conflicts
* **Zero configuration** — activate and you're protected
* **No external services** — everything runs on your server, no subscriptions
* **No performance impact** — validation adds microseconds, not seconds

= Features (Free) =

* **Automatic bot blocking** — works the moment you activate, no setup needed
* **4 protection levels** — Learning, Permissive, Balanced, and Strict — choose how aggressive you want to be
* **Dashboard overview** — see blocked vs verified orders at a glance with a 7-day chart
* **Order status tracking** — know which orders were flagged, passed, or blocked
* **IP whitelist** — let trusted addresses through, supports CIDR notation
* **API key authentication** — for headless and custom checkout setups
* **Works with all checkout types** — classic, block-based, and all payment gateways
* **HPOS compatible** — works with High-Performance Order Storage
* **WooCommerce logging** — full integration with WooCommerce Status logs

= Pro Features =

Take control with advanced tools:

* **Smart logging** — choose what gets logged: nothing, blocked attempts only, or everything with full details
* **Recent blocks feed** — see the last 50 blocked attempts right on your dashboard, with email, payment method, and block reason
* **Automatic CDN/proxy detection** — correctly identifies visitor IPs behind Cloudflare, Sucuri, or Akamai without manual configuration
* **Stronger permissive mode** — adds referrer verification on top of session checks for tighter bot detection
* **Checkout details in logs** — see exactly which email and payment method bots tried to use
* **Customer blocklist** — block repeat offenders by email, name, address, phone, IP, or postal code
* **Order block metabox** — add customers to the blocklist directly from any order screen

== Frequently Asked Questions ==

= Does this slow down checkout? =

No. Validation happens locally in microseconds. No external API calls, no waiting on third-party services.

= Will this block real customers? =

Very unlikely. The default Balanced mode is tuned to avoid blocking legitimate orders. If you want to be cautious, start with Learning mode — it logs what would be blocked without actually blocking anyone.

= Does it work with Block Checkout? =

Yes. Works with both classic checkout and the newer block-based checkout.

= What about PayPal, Stripe, and other payment gateways? =

All major gateways work normally. Payment confirmations from gateways aren't affected by checkout validation.

= I run a headless store. Will this break my setup? =

Not if you configure it. Add your frontend's server IP to the whitelist, or use API key authentication. Both options let legitimate automated requests through.

= Do I still need CAPTCHA? =

Up to you. This plugin catches bots that CAPTCHA misses (the ones hitting your API directly). You can use both together, or drop CAPTCHA entirely to reduce checkout friction.

= How do I know it's working? =

Check the dashboard widget for a quick overview, or go to WooCommerce → Status → Logs and filter by "carticy-checkout-shield" for detailed logs.
