WooCommerce: need hook when admin manually creates order

Question

One of my sites uses WooCommerce. The client wants to manually create orders occasionally from within order admin (WooCommerce > Orders > Add Order). I need to do some add

Answer 1

I've recently found that WooCommerce documentation is basically non-existent in a practical sense. However, have you tried either the woocommerce_admin_order_actions_end or woocommerce_admin_order_actions_start hooks?

Answer 2

It looks like woocommerce_process_shop_order_meta will work for me,

add_action( 'woocommerce_process_shop_order_meta', 'woocommerce_process_shop_order', 10, 2 );
function woocommerce_process_shop_order ( $post_id, $post ) {
        // my code here
}
