get customer payment ids from CIM

Question

How can I get customer payment method ids from AuthorizeNetCIM_Response object?

There's a method in AuthorizeNetCIM_Response which is supposed to return payment method ids

public function getCustomerPaymentProfileIds()
{
    $ids = (array)$this->xml->customerPaymentProfileIdList;
    return $ids["numericString"];
}

but calling this function results in error

Notice: Undefined index: numericString

The response object outputs as:

AuthorizeNet_AuthorizeNetCIMResponse Object

                                )
                        )
                )
        )

and I supposed to get the array of paymentProfiles as

$response->xml->profile->paymentProfiles;

but it only returning the first element of paymentProfiles not an array.

Answer 1

Since there can be more then one, as per your example, you need to loop through each profile to get that information:

$paymentProfileIds = array();
foreach ($response->xml->profile->paymentProfiles AS $profile) {
    $paymentProfileIds[] = (string) $profile->customerPaymentProfileId;
}

print_r($paymentProfileIds);
