Place a hold on the credit card and charge using Stripe paymentIntent

Question

I want to build the process below

1. When a client presses the Book button, we need to place a hold on the credit card for the amount of the transaction

I think the hold does not charge the card, ie the money does not leave the card The hold just checks that the money is available and reserves it for a few days

2. Within these 7 days, I call another API to complete the charge, to cancel the hold, or just let the hold expire.

3. If a client books an appointment, the money goes on hold and then, after a day or so, he cancels, the hold should be released I checked the Stripe API doc, but I am not sure how to do this process. I think it must to using the paymentIntent API. Please explain to me what process I must do.

            $stripe = new \Stripe\StripeClient(env('STRIPE_SECRET_KEY'));
   
            $getPaymentMethod = $stripe->paymentMethods->all([
                'customer' => $request->customerId,
                'type' => 'card',
            ]);
            $createIntent = $stripe->paymentIntents->create([
                'amount' => $request->price * 100,
                'currency' => 'usd',
                'payment_method' => $getPaymentMethod->data[0]->id,
                'payment_method_types' => [$request->paymentType],
                'customer' => $request->customerId,
                'capture_method' => 'manual',
                'description' => 'The payment of the appointment',
            ]);
   
            $confirmPaymentIntent = $stripe->paymentIntents->confirm(
                $createIntent->id,
                ['payment_method' => $getPaymentMethod->data[0]->id]
            );
   
            $captureIntent = $stripe->paymentIntents->retrieve($confirmPaymentIntent->id);
   
            $results = $captureIntent->capture($confirmPaymentIntent->id);
   
            return $results;
   

I tried this code so it is working and the payment capture. But it didn't charge the money on the stripe and the balance is $0.00. I am not sure it is correct and how to do next step for complete. Please help me. what should I?
