In laravel you can use Observers , please see this

observer code sample:

<?php

namespace App\Observers;

use App\Models\Payment;

class PaymentObserver
{
    public function created(Payment $payment)
    {
        $wallet = $payment->wallet;
        $wallet->balance = $payment->price;
        $wallet->save();
    }

    public function updated(Payment $payment)
    {
        if($payment->wasChanged('price')){
            $wallet = $payment->wallet;
            $wallet->balance = $payment->price;
            $wallet->save();
        }
        
    }
}
