Depending on the payment provider you integrate with, there may be additional payment data that you want to send. If so, you can include this data in the createOrder REST request. Each payments object in the request can include a customProperties subobject that you can use to send additional data as key/value pairs. For example:
...
"payments": [
{
"endYear": 2018,
"cardTypeName": "Visa",
"nameOnCard": "Fred Smith",
"customProperties": {
"MonthlyCharge": "$77",
"NumberOfPayments": "12"
},
"cardCVV": "123",
"type": "card",
"cardType": "visa",
"endMonth": "02",
"cardNumber": "4055011111111111"
}
],
...
