Woocommerce which hook to use for order status changes - wordpress

Question

In my custom plugin I need to catch every time an order status changes from wc_on_hold to wc_completed so I tried to write down:
function so_status_completed( $order_id, $old_status, $new_status ) {
// if user is active , then get order amount and do all other personal calculations
global $wpdb;
$order = wc_get_order( $order_id );
//$payment_method = $order->get_payment_method(); //returns payment method bacs,cheque,cod etc
$user_id = $order->get_user_id();
$total = $order->get_total();
$order_data = $order->get_data();
//$order_total = $order->get_formatted_order_total();
$order_total = $order->get_total();
echo '<script>console.log("Debug Objects: Check order_total ' . $order_total. '");</script>';
}
add_action('woocommerce_order_payment_status_changed','so_status_completed',10,1);
But when I tried to change an order test from suspended to completed, I couldn't get on Chrome's Console that echo giving me the order price.....maybe using add_action isn't the right way to put a listener to that event?
Plus, since I am just here, I am using $order-get_total() which I searched on the net about his functionality but no deep docs found so I want to ask you if that method is the right one to retrieve order amount without fee applied?
Thanks! Cheers!!!

"I need to catch every time an order status changes from wc_on_hold to wc_completed"
You would need to change your hook to woocommerce_order_status_changed.
"I couldn't get on Chrome's Console that echo giving me the order price"
You can't use javascript and console.log in this hook. You would need to either use the die function or the error_log function to log it to your debug.log file.
Using die function
add_action('woocommerce_order_status_changed', 'so_status_completed', 10, 3);
function so_status_completed($order_id, $old_status, $new_status)
{
$order = wc_get_order($order_id);
//$order_total = $order->get_formatted_order_total();
$order_total = $order->get_total();
die($order_total);
}
Using error_log function
dd_action('woocommerce_order_status_changed', 'so_status_completed', 10, 3);
function so_status_completed($order_id, $old_status, $new_status)
{
$order = wc_get_order($order_id);
//$order_total = $order->get_formatted_order_total();
$order_total = $order->get_total();
error_log(print_r('order total: ' . $order_total, true));
}
Second question
"since I am just here, I want to ask you if $order-get_total() is the right one to retrieve order amount without fee applied?"
You might want to take a look at the $order->get_subtotal() for the totals before shipping, coupons and taxes:
