Stripe Webhooks not working

I'm implementing a stripe checkout for my client who's a limousine booking company. I need to insert data into the database after a successful Stripe transaction but it appears that my webhook is not being called at all. I've been trying to figure this out for 5 hours but couldn't. Any help is much appreciated! As far as code, here is my endpoint in web.php:

Route::post('/stripe/webhook', [StripeWebHookHandler::class, 'handleWebhook']);

Here's my function in my BookingController:

  public function bookRide(Request $request)
{

    /*
    These prices are for if the user selects point-to-point 
    the prices are:
    sedan  add that to the price of the sedan per mile + 20% 
    mini suv: , 
    suv: 0,  
    For the van, no matter what service, the customer needs to call you email notification 

    */
    $admin = User::find(1); 
    $data = $request->only([
        'first_name', 'last_name', 'email', 'phone_number', 'service_type',
        'pickup_date_time', 'pickup_location', 'dropoff_location',
        'num_passengers', 'num_luggage', 'vehicle', 'calculated_distance', 
        'calculated_duration',
        'booster_seat_addon',
    ]);

    $validate = $this->validateBooking($data);

    if ($validate->fails()) {
        return redirect()->route('reservation')->withErrors($validate);
    }

    $product = $this->stripe->products->retrieve($request->vehicle);
    $prices = $this->stripe->prices->all(['product' => $product->id]);
    $price = $prices->data[0]->unit_amount;
    $distance = floatval($request->calculated_distance);
    $totalPrice = 0;
    $surCharge = 0.20; // 20% surcharge 
    // Calculate pricing based on requested pricing model 
    $basePrice = 0; // initialize to <?php

I have also imported the stripe webhook controller into my BookingController class like so: use App\Http\Controllers\StripeWebhookHandler;

Here is my stripe webhook handler class:
