Hilt Pay uses X-Hilt-Key authentication, checks the connection with GET /v1/products?limit=1, lets merchants choose Hilt checkouts from GET /v1/products, and creates hosted checkout handoffs through POST /v1/products/{product_id}/handoff-link. Mapped Hilt templates should use the configured WooCommerce identity type, which defaults to CUSTOM.

Checkout Blocks
The plugin declares Cart and Checkout Blocks compatibility and registers a no-build Checkout Blocks payment method bridge. It delegates processing to the WooCommerce payment gateway and expects WooCommerce to follow the returned offsite redirect URL.
