Why Your Klaviyo WooCommerce Integration Keeps Breaking (And How to Fix It)
The Klaviyo WooCommerce integration breaks repeatedly for thousands of stores—every few weeks, Placed Order events stop tracking and revenue disappears from dashboards. The causes are consistent: caching plugins block API requests, single-page checkout bypasses event tracking, security plugins rate-limit Klaviyo’s webhooks, and WooCommerce HPOS migration disrupts existing integrations. The Klaviyo plugin relies on client-side JavaScript and webhooks that fail silently when any of these conflicts occur. Server-side tracking bypasses these issues entirely by firing events directly from WooCommerce hooks on your server—no browser JavaScript, no webhook dependencies, no caching conflicts.
