This hook is triggered on synchronizing custom product data for every product property and metadata, to perform custom actions when a product is being synced from the origin site to the child sites. Developers can use this hook to ensure custom fields, third-party plugin data, or specific business logic runs its own action and custom processing.

Below is an example of how you might use this action to further process when a custom meta field (_custom_shipping_time):

add_action( 'woogc/ps/synchronize_product/synchronize_product_data', 'my_sync_custom_shipping_time', 10, 5 );

function my_sync_custom_shipping_time( $prop_title, $prop_value, $child_product, $main_product_data, $origin_product_blog_ID ) {
    if ( $prop_title === '_custom_shipping_time' ) {
        // Assuming _custom_shipping_time is a meta field in the original product
        $child_product->update_meta_data( '_custom_shipping_time', $prop_value );
        $child_product->save(); // Don't forget to save the product after updating
    }
}
