Authorize.Net API: Define a default credit card for charging - asp.net

Question

I have saved multiple Payment Profiles for a single customer in authorize.net. Each Payment Profile contains a credit card information.
I have two questions
1) Which credit card will be charge, When I am charging a transaction of customer who have multiple Payment Profile.
2) Is there any way to define a default credit card to charge.
Thanks

Answer 1

Currently there is no way to create a default payment profile for payments. One must always be passed with each createCustomerProfileTransactionRequest call.

Answer 2

in updateCustomerPaymentProfileRequest page , I see this content:
defaultPaymentProfile : When set to true, this field designates the payment profile as the default payment profile.
When a default payment profile has been designated, you can use getCustomerPaymentProfileRequest with customerProfileId as the only parameter.

Answer 3

it will work 100% to set default payment profile
$paymentprofile = new AnetAPI\CustomerPaymentProfileExType();
$paymentprofile->setCustomerPaymentProfileId($payment_detail['payment_profile_id']);
$paymentprofile->setBillTo($billto);
$paymentprofile->setPayment($paymentCreditCard);
$paymentprofile->setDefaultPaymentProfile($payment_detail['default_payment']);

Answer 4

All the other answers don't allow for UPDATING an existing payment profile but only CREATING a new payment profile. I know this is PHP but hopefully it will help someone, since I couldn't find anything related to this.
function paymentProfileUpdateDefault($profile_id, $payment_profile_id) {
$success = false;
$message = '';
$error_message = '';
// Create a merchantAuthenticationType object with authentication details
$merchantAuthentication = new AnetAPI\MerchantAuthenticationType();
$merchantAuthentication->setName($GLOBALS["authorizeNet"]["login_id"]);
$merchantAuthentication->setTransactionKey($GLOBALS["authorizeNet"]["transaction_key"]);

$refId = 'ref' . time();
$request = new AnetAPI\GetCustomerPaymentProfileRequest();
$request->setMerchantAuthentication($merchantAuthentication);
$request->setRefId($refId);
$request->setCustomerProfileId($profile_id);
$request->setCustomerPaymentProfileId($payment_profile_id);
$controller = new AnetController\GetCustomerPaymentProfileController($request);
// Get the response
$response = $controller->executeWithApiResponse($GLOBALS["authorizeNet"]["api_endpoint"]);
if (($response != null) && ($response->getMessages()->getResultCode() == "Ok") ){
$billto = $response->getPaymentProfile()->getbillTo();
$old_billto_obj = json_encode($billto, JSON_FORCE_OBJECT);
$old_billto_arr = json_decode($old_billto_obj, true);
$billto->setFirstName($old_billto_arr['firstName']);
$billto->setLastName($old_billto_arr['lastName']);
$old_paymentprofile = $response->getPaymentProfile();
$old_paymentprofile_obj = json_encode($old_paymentprofile, JSON_FORCE_OBJECT);
$old_paymentprofile_arr = json_decode($old_paymentprofile_obj, true);

$paymentCreditCard->setCreditCard($creditCard);
