Answer 1

You can use a custom function hooked in woocommerce_order_status_completed hook, this way:

add_action( 'woocommerce_order_status_completed', 'custom_wc_order_complete', 10, 2 );
function custom_wc_order_complete( $order_id, $order ) {
    // Here comes your code (doing something), optionally using the $order_id argument
}

This function will be triggered when the order status will become "completed" for a specific $order_id (argument).

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
