Merchant has the option to mask the inputs on the payment page fields for PAN and CSC, so that card-holders in public environments can feel more secure entering their card information.
maskPaymentInfo is the flag that can be used to mask PAN and CSC. When "true" it enables the masking, when "false" or deleted it does not mask the PAN.
While creating an order pass the following to mask the PAN and CSC:
{
"action": "PURCHASE",
"amount" : {
"currencyCode" : "AED",
"value" : 399
},
"merchantAttributes": {
"maskPaymentInfo" : true
}
}
