WooCommerce Data — Orders, Products & APIs

Reference for HPOS-compatible data access, product/customer CRUD, Store API, and REST API integration.

1. HPOS (High-Performance Order Storage)

Since WooCommerce 8.2, HPOS is the default order storage for new installs. Orders are stored in custom tables, not wp_postmeta.

Accessing Order Data (HPOS-Compatible)

// Always use CRUD methods — never direct SQL or get_post_meta().
$order = wc_get_order( $order_id );
