Payments with Laravel Omnipay (mollie gateway) - laravel

Question

I'm currently stuck trying to create a payment with Omnipay. I have the following libraries installed in my project:
https://github.com/barryvdh/laravel-omnipay
https://github.com/thephpleague/omnipay-mollie
But I'm having problems starting. I see in the example that I need these params:
$params = [
'amount' => $order->amount,
'issuer' => $issuerId,
'description' => $order->description,
'returnUrl' => URL::action('PurchaseController#return', [$order->id]),
];
But what's the $issuerId? I would like to have an integration with Mollie.
Does someone maybe has an example of using laravel Omnipay with Mollie?
UPDATE:
I'm trying to submit my form with an ajax call. In my PHP function I have the following code:
$gateway = Omnipay\Omnipay::create('Mollie');
$gateway->setApiKey('test_gSDS4xNA96AfNmmdwB3fAA47zS84KN');
$params = [
'amount' => $ticket_order['order_total'] + $ticket_order['organiser_booking_fee'],
'description' => 'Kapelhoek wijkfeesten',
'returnUrl' => URL::action('EventCheckoutController#fallback'),
];
$response = $gateway->purchase($params)->send();
if ($response->isSuccessful()) {
// payment was successful: update database
print_r($response); die;
} elseif ($response->isRedirect()) {
// redirect to offsite payment gateway
return $response->getRedirectResponse(); die;
} else {
// payment failed: display message to customer
echo $response->getMessage(); die;
}
But now I'm getting the following console error:
XMLHttpRequest cannot load https://www.mollie.com/payscreen/select-method/PRMtm6qnWG. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://kapelhoektickets.dev' is therefore not allowed access.
How can I fix this?

But what's the $issuerId?
Issuer ID is The issuer's unique identifier, for example ideal_ABNANL2A. When creating a payment, specify this ID as the issuer parameter to forward the consumer to their banking environment directly.
You can see a list of available issuers by calling this API url:
https://api.mollie.nl/v1/issuers
as stated in https://www.mollie.com/be/docs/reference/issuers/list
To read more about the issuer visit this part of the API-documentation:
