Hello forum, we are trying to create the SO which will be paid by credit card chosen out of all the credit cards on file for specific customer.

To get list of credit cards on file we are loading customer record:
nlapiLoadRecord("customer", 281);

But in customer object the array we are getting for credit cards for some reason doesn't show their internalIDs:

--------------------------
"creditcards": [
{
"cardstate": {
"name": "Expired",
"internalid": "EXPIRED"
},
"ccdefault": false,
"ccexpiredate": "10/2009",
"ccnumber": "************8527",
"paymentmethod": {
"name": "Master Card",
"internalid": "4"
}
},
{
"cardstate": {
"name": "Unknown",
"internalid": "UNKNOWN"
},
"ccdefault": false,
"ccexpiredate": "11/2016",
"ccnumber": "************2300",
"paymentmethod": {
"name": "Master Card",
"internalid": "4"
}
},
{
"cardstate": {
"name": "Unknown",
"internalid": "UNKNOWN"
},
"ccdefault": true,
"ccexpiredate": "01/2016",
