omnipay - AuthorizeNet_CIM - omnipay

Question

I am trying to setup a payment processor using omnipay-authorizenet AuthorizeNet_CIM. Not a lot of documentation on this.
Step 1) I create the gateway object successfully and can make requests to the authorize.net sandbox server.
Step 2) is to "create a card" for future use with Token Billing: $gateway->createCard() . This is successful.
From the General Omnipay Token Billing documentation:
"... createCard($options) - returns a response object which includes a cardReference, which can be used for future transactions..."
I don't see a specific 'cardReference' in the above createCard() response object.
So I create a $cardRef array and grab the returned response CustomerProfileId and CustomerPaymentProfileId .
$profileResult['customerProfileId']=$response->getCustomerProfileId();
$profileResult['paymentProfileId']=$response->getCustomerPaymentProfileId();
Step 3) is a function to generate the purchase which fails:
function create_transaction($cardRef,$amount,$description,$invoice_number){
global $status, $gateway;
try {
// Send purchase request
$response = $gateway->purchase(
array(
'cardReference' => $cardRef ,
'amount' => $amount,
'currency' => 'USD',
'description' => $_POST['description'],
'transactionId' => $invoice_number
)
)->send();
if ($response->isSuccessful()) {
// Payment was successful
$status.='Success: '.$response->getMessage();
} elseif ($response->isRedirect()) {
// Redirect to offsite payment gateway
$response->redirect();
} else {
// Payment failed
$status.='Transaction Failure: '.$response->getMessage();
}
} catch (Exception $e) {
$status.='<strong>Error:</strong> '.$e->getMessage(). "<br/>";
}
}
The purchase fails and when I look at the Response object it seems the Request is not populating the cardReference object.
[cardReference] => Omnipay\AuthorizeNet\Model\CardReference Object
(
[customerProfileId:Omnipay\AuthorizeNet\Model\CardReference:private] =>
[paymentProfileId:Omnipay\AuthorizeNet\Model\CardReference:private] =>
[shippingProfileId:Omnipay\AuthorizeNet\Model\CardReference:private] =>
)
I am obviously not passing the correct cardReference data to the purchase method.
Any help would be greatly appreciated.
Thanks

Answer 1

I apparently needed to use the undocumented Omnipay method;
$response->getCardReference();
to get a cardReference object to pass to my create_transaction() function.
All fixed.
