When WooCommerce Checkout Blocks are broken, the checkout may fail differently from the classic shortcode checkout. The page can render, but the Store API, block scripts, payment method area or validation state can stop the buyer before an order exists.
The useful split is whether the failure lives in Store API responses, block hydration, shipping recalculation, payment method rendering, extension compatibility, cache or a JavaScript error that only appears after the checkout state changes.
Evidence should answer these questions:
- Does the checkout block render but miss payment methods? - Does Store API return cart, shipping and payment data consistently? - Does the failure appear after country, coupon or shipping changes? - Is a block extension or payment integration failing after hydration? - Does the buyer reach confirmation, or only a broken block state?
CashFlowCanary treats broken Checkout Blocks as a conversion incident when a controlled journey reaches the block checkout without a usable final path. The report keeps only the technical signals required to reproduce the break, excluding buyer identity, payment information and precise cart contents.

This guide complements WooCommerce no payment methods available, WooCommerce checkout validation error, WooCommerce checkout stuck and WooCommerce checkout 500 error. Together they separate Checkout Blocks failures from missing payment methods, validation, frozen checkout and server errors.
