Laravel Cashier single Charge for api

Hello Everyone. I am using laravel cashier for payments. and i have implemented it on web side here is what it looks like

public function payment(Request $request)
{
    $intent = auth()->user()->createSetupIntent();
    return view('page.payment', compact('intent'));
}

public function submitPayment(Request $request)
{
    $user          = auth()->user();
    $paymentMethod = $request->input('payment_method');

    try {
        $user->createOrGetStripeCustomer();
        $user->updateDefaultPaymentMethod($paymentMethod);
        $user->charge(3 * 100, $paymentMethod);
    } catch (\Exception $exception) {
        return back()->with('error', $exception->getMessage());
    }
    return redirect()->back()->with('success', 'Payment done.');
}

This thing is working fine. Now the Problem is i want to create a payment API in Laravel for mobile. And i have no idea how to do that should i send intent and they will give me Payment method or some thing else.

Also, I Just read online somewhere that you will receive few fields from api include Number, Expiry Year, Expiry Month, CVC and Name using these fields you can create a stripe Token and use that for Payment.

So i ended up like This but Not Working. Here is the Code.

public function apiSubmitPayment(Request $request)
{	
	$stripe = array(
    	"secret_key"      => config('services.stripe.stripe_key')
        "publishable_key" => config('services.stripe.stripe_secret')
	);

    \Stripe\Stripe::setApiKey($stripe['secret_key']);
    $stripeToken = Token::create(array(
    	"card" => array(
        	"number"    => $request->get('number'),
            "exp_month" => $request->get('exp_month'),
            "exp_year"  => $request->get('exp_year'),
            "cvc"       => $request->get('cvc'),
            "name"      => $request->get('name')
		)
	));

	$user = auth()->user();

	try {
    	$user->createOrGetStripeCustomer();
		$user->updateDefaultPaymentMethod($stripeToken);
        $user->charge(3 * 100, $stripeToken);
	} catch (\Exception $exception) {
    	return $this->response(Response::HTTP_OK, $exception->getMessage(), []);
	}

	return $this->response(Response::HTTP_OK, 'Data fetched Successfully', [
    	'advert' => new AdvertResource($advert),	
	]);
}

Any Help would be great full please help me out of this i really need a solution for this.
