When WooCommerce order confirmation is missing, the checkout can look successful until the last signal disappears. The customer may submit payment, leave the checkout page, then never see the thank you page, order received URL or reliable confirmation marker.
This is not the same incident as a refused card or a validation message. The critical question is whether the controlled purchase path reached a safe confirmation state after the final request, payment callback or redirect.
Useful evidence should answer five questions:
- Did the checkout submit and leave the form cleanly?
- Did the gateway callback or redirect return to WooCommerce?
- Is the `order-received` URL reachable and consistent?
- Does cache, security middleware or a plugin hide the thank you page?
- Is there a durable confirmation signal without exposing customer data?
CashFlowCanary treats missing confirmation as a checkout incident only when the synthetic journey cannot prove the order-received step. It keeps the evidence filtered and avoids customer identity, payment data and cart contents. See the monitoring scope in features, compare plans, or request a free audit.
This guide complements WooCommerce checkout not working, WooCommerce place order button not working, WooCommerce payment failed and WooCommerce checkout validation error. Together they separate missing confirmation from form, payment, validation and wider broken checkout symptoms.
