Help with payment gateway payment with tokenization

[hsnuwaninfo]

I included the our payment gateway providers iframe in merchantgateway.php. And I capture the token inside callback according to the WHMCS payment gateway sample code. Initial payment is working and a token is returned. I tried to test recurring payment by changing the next due date to yesterday date and run the cron. But the automatic recurring payment does not happen. I tried to implement whmcs hook on callback to do the recurring payment. Am going the right direction? I would be much grateful to you if could help on this

 

My code is given below

 

payment module

 

<?php

function paybank_config()
{
$configarray = array(
"FriendlyName" => array("Type" => "System", "Value" => "XXXX Bank"),
);
return $configarray;
}

function paybank_link($params)
{

$client_hash = 'xxxxxxxxxxxxxxxxxxxxxxxx';

$code = '<iframe id="showEntry" width="100%" height="350" src="https://[payment-gateway-url]?clientIdHash='.$client_hash.'&paymentAmount='.$params['amount'].'"></iframe>';

$_SESSION['paybank_amount'] = $params['amount'];
$_SESSION['paybank_invoiceid'] = $params['invoiceid'];

return $code;

}

function paybank_refund($params)
{

# Gateway Specific Variables
$gatewayusername = $params['username'];
$gatewaytestmode = $params['testmode'];

# Invoice Variables
$transid = $params['transid']; # Transaction ID of Original Payment
$amount = $params['amount']; # Format: ##.##
$currency = $params['currency']; # Currency Code
# Client Variables
$firstname = $params['clientdetails']['firstname'];
$lastname = $params['clientdetails']['lastname'];
$email = $params['clientdetails']['email'];
$address1 = $params['clientdetails']['address1'];
$address2 = $params['clientdetails']['address2'];
$city = $params['clientdetails']['city'];
$state = $params['clientdetails']['state'];
$postcode = $params['clientdetails']['postcode'];
$country = $params['clientdetails']['country'];
$phone = $params['clientdetails']['phonenumber'];

# Card Details
$cardtype = $params['cardtype'];
$cardnumber = $params['cardnum'];
$cardexpiry = $params['cardexp']; # Format: MMYY
$cardstart = $params['cardstart']; # Format: MMYY
$cardissuenum = $params['cardissuenum'];

# Perform Refund Here & Generate $results Array, eg:
$results = array();
$results["status"] = "success";
$results["transid"] = "12345";

# Return Results
if ($results["status"] == "success")
{
return array("status" => "success", "transid" => $results["transid"], "rawdata" => $results);
}
elseif ($gatewayresult == "declined")
{
return array("status" => "declined", "rawdata" => $results);
}
else
{
return array("status" => "error", "rawdata" => $results);
}
}
