Stripe Webhooks

Hi.

Im trying to get my webhooks sorted on the localhost. I can receive the Webhooks and log it into the logs but when i try to use the data, like update the user etc it doesn't do anything!

Heres one Webhook::

<?php

namespace App\Http\Controllers\Webhooks;

use App\Models\Common\Ledger;
use App\Models\User;
use Laravel\Cashier\Http\Controllers\WebhookController as CashierController;
use Log;
use Stripe\Stripe;
use Illuminate\Http\Response;

class StripeWebhooksController extends CashierController
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function __construct()
    {
        Stripe::setApiKey(config('services.stripe.secret'));
    }

public function handleCheckoutSessionCompleted($payload)
    {
        if ( ! $this->eventExistsOnStripe($payload['id'])) {
            return;
        }

        \Log::alert('checkout.session.completed');
        \Log::alert(json_encode($payload['data']['object']));

        // Save the customer_id to the user table
        $client_reference_id = json_encode($payload['data']['object']['client_reference_id']);

        User::where('id', $client_reference_id)->update([
            'stripe_id' => json_encode($payload['data']['object']['customer'])
        ]);

        return new Response('Payment Session Completed', 200);
    }

Any ideas?

Many thanks This should save the customer object to the user database. If i log the client_reference_id to the Log, it is correct and it finds the user.
