It executes headless „ghost transactions“ on a configurable schedule to verify that your store’s entire checkout pipeline — from cart addition through payment processing — is fully functional. **Core Features:** * **Ghost Runner Engine** — Automatically creates a synthetic $0.00 test product, adds it to cart, and processes a full checkout cycle using an internal mock payment gateway. * **Configurable Scheduling** — Choose from 9 automated test intervals (ranging from every 5 minutes up to 24 hours) powered by WordPress Cron. * **Instant Email Alerts** — Receive a high-priority HTML email notification the moment a checkout failure is detected. * **Last 30 Checks Timeline** — Visual status timeline showing your checkout health over the past 30 check cycles. * **Auto-Cleanup Protocol** — All synthetic test data (products, orders, cart items) is permanently purged immediately after each test to protect your store analytics. * **HPOS Compatible** — Fully compatible with WooCommerce High-Performance Order Storage. * **Zero External Dependencies** — No CDN calls, no tracking scripts, no external API connections. Everything runs locally. **How It Works:** 1. CheckOO creates a hidden, $0.00 virtual product on the fly. 2. It adds this product to an internal cart session. 3. It processes checkout through a hidden mock payment gateway that only responds to internal test requests. 4. It verifies the order was created successfully in the database. 5. It immediately purges all synthetic data — the test product, the order, and all associated metadata. 6. If any step fails, an alert email is dispatched to the store administrator. **Who Is This For?** * WooCommerce store owners who want automated confidence that their checkout works. * Agencies managing multiple client stores who need proactive monitoring. * Developers who want to catch checkout-breaking changes before customers do. ### Third-Party Services This plugin does not connect to or rely on any third-party external services, APIs, or CDNs. All operations are performed entirely within your WordPress installation. No data is transmitted externally. ## Screenshots [⌊CheckOO dashboard overview with status cards and uptime timeline.⌉⌊CheckOO dashboard overview with status cards and uptime timeline.⌉[ CheckOO dashboard overview with status cards and uptime timeline.

No. CheckOO creates a temporary $0.00 virtual product and a synthetic order that are immediately and permanently deleted after each test cycle. Your sales reports, revenue analytics, and stock counts are never affected. ### Will customers see the test payment gateway? No. The internal mock gateway is programmatically filtered out of the public-facing checkout page. It is only activated during internal test cycles and is invisible to shoppers. ### Does this plugin make any external API calls? No. CheckOO operates entirely within your WordPress installation. It does not connect to any external services, CDNs, or APIs. All processing is done locally. ### What happens if a test fails? CheckOO immediately sends a high-priority HTML email to the configured alert address with the failure details, timestamp, and a direct link to the CheckOO dashboard. ### Is this compatible with WooCommerce HPOS? Yes. CheckOO declares full compatibility with WooCommerce High-Performance Order Storage (Custom Order Tables) and uses CRUD methods for all order operations. ### Can I run a test manually? Yes. The CheckOO dashboard includes a „Run Test Now“ button that executes an immediate checkout test and displays the result. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “CheckOO – Checkout Monitor & Uptime Tracker for WooCommerce” is open source software.
