    "amount" : AMOUNT,
    "api" : "ENTER_YOUR_OWN_API_KEY",
    "type" : "P2P"/"avdpg"
}'// Here in type P2P for only UPI payments, 
and avdpg have UPI Netbanking all types of cards and 
also EMI option with advance Gateway.

$apiUrl = 'https://smartinfinitypay.com/process/checkjson.php';
$apiKey = 'ENTER_YOUR_OWN_API_KEY';

$data = array(
    'orderid' => 'ORDER_ID',
