Payment Gateway Redirects Are Swallowing Your WooCommerce Purchase Events
WooCommerce stores using off-site payment gateways like PayPal, Klarna, and 3DS lose an estimated 15-30% of purchase events because customers leave the payment success screen before the thank-you page fires the tracking pixel (WordPress.org support forums, 2026). The problem compounds with ad blockers, consent rejection, and broken Enhanced Conversions setups — creating a data gap that client-side tracking cannot close. Server-side tracking captures purchase events from the WooCommerce order webhook, bypassing the redirect entirely.
