Query: Adding Credit Card type and expiry date in FOP in Fare_PricePNRWithBookingClass request

[skills-up]

Hello,

I'm trying to add credit card type and expiry date in form of payment for Fare_PricePNRWithBookingClass as below:

            $options['formOfPayment'] = [
                new FormOfPayment([
                    'type' => FormOfPayment::TYPE_CREDIT_CARD,
                    'creditCardNumber' => '123456789012345678',
                    'creditCardType' => 'VI',
                    'vendorCode' => 'VI',
                    'expiryDate' => '1231',
                ]),
            ];

However, the resultant information has only this information:

<ns1:pricingOptionGroup>
  <ns1:pricingOptionKey>
    <ns1:pricingOptionKey>FOP</ns1:pricingOptionKey>
  </ns1:pricingOptionKey>
  <ns1:formOfPaymentInformation>
    <ns1:formOfPayment>
      <ns1:type>CC</ns1:type>
      <ns1:creditCardNumber>123456789012345678</ns1:creditCardNumber>
    </ns1:formOfPayment>
  </ns1:formOfPaymentInformation>
</ns1:pricingOptionGroup>

Neither creditCardType nor vendorCode works. expiryDate doesn't get added either.

How should I specify the form of payment here to include complete credit card details?

Or, should I use some alternative mechanism to add these details? The reason I want to add it during pricing is to get any credit card fee included in response.
