wp-woocommerce

Use when building, extending, or debugging a WooCommerce plugin — custom product types, payment gateways (WC_Payment_Gateway, process_payment(), process_refund()), shipping methods (WC_Shipping_Method, calculate_shipping()), CRUD via WC_Product / WC_Order / WC_Customer (wc_get_product, wc_create_order, wc_get_orders, get_meta, update_meta_data), HPOS compatibility (FeaturesUtil::declare_compatibility, wc_get_orders instead of WP_Query on posts), REST API extensions (woocommerce_rest_prepare, woocommerce_rest_pre_insert, Store API woocommerce_store_api_register_endpoint_data), cart/checkout blocks (registerCheckoutFilters, extensionCartUpdate, SlotFills), key hooks (woocommerce_cart_calculate_fees, woocommerce_checkout_fields, woocommerce_order_status_changed, woocommerce_payment_gateways), or WooCommerce subscription/coupon/webhook logic. Triggers: \"WooCommerce extension\", \"custom product type\", \"payment gateway\", \"hook into WooCommerce checkout\", \"WC_Order\", \"wc_create_order()\", \"wc_get_product()\", \"add a shipping method\", \"WooCommerce REST API\", \"HPOS compatible\", \"FeaturesUtil::declare_compatibility\", \"cart block\", \"checkout block filter\", \"woocommerce_payment_gateways\", \"WC_Product CRUD\", \"Store API endpoint\", \"extend WooCommerce\", \"woocommerce_cart_calculate_fees\", \"woocommerce_checkout_fields\", \"process_payment()\", \"process_refund()\", \"woocommerce_rest_prepare_product\", \"registerCheckoutFilters\", \"WC webhook HMAC\", \"WC coupon CRUD\", \"wc_get_orders HPOS\". Not for: Freemius monetisation — use wp-freemius; plain WordPress post/taxonomy work without WooCommerce.
