Description: This tutorial demonstrates you on how to integrate FraudLabs Pro fraud detection into BluePay payment.
PHP
Create a new table to store the transaction value of FraudLabs Pro and BluePay payment processing. This table will be used during the settlement, void or refund process.
CREATE TABLE `fraudlabs_pro` ( `flp_transaction_id` CHAR(15) NOT NULL, `flp_status` VARCHAR(10) NOT NULL, `bluepay_transaction_id` VARCHAR(15) NOT NULL, PRIMARY KEY (`flp_transaction_id`) ) COLLATE='utf8_general_ci' ENGINE=MyISAM;

Integrate FraudLabs Pro fraud detection logic with your BluePay code. This code will perform a simple validation check of one credit card purchase and perform the appropriate action based on the fraud validation result.
// Include FraudLabs Pro library
require_once 'PATH_TO_FRAUDLABSPRO/lib/FraudLabsPro.php';
// Include BluePay library
require_once 'PATH_TO_BLUEPAY/lib/BluePayPayment_BP10Emu.php';
// Create a free user account at http://www.fraudlabspro.com, if you do not have one
FraudLabsPro\Configuration::apiKey('your_fraudlabspro_api_key');
// Check this transaction for possible fraud. FraudLabs Pro support comprehensive validation check,
// and for this example, we only perform the IP address, BIN and billing country validation.
// For complete validation, please check our developer page at http://www.fraudlabspro.com/developer
$orderDetails = [
'order' => [
'amount' => $_POST['amount'],
'paymentMethod' => FraudLabsPro\Order::CREDIT_CARD,
],
'card' => [
'number' => $_POST['cardNumber'],
],
'billing' => [
'country' => $_POST['country'],
],
];
// Sends the order details to FraudLabs Pro
$fraudResult = FraudLabsPro\Order::validate($orderDetails);
// This transaction is legitimate, let's submit to BluePay
if($fraudResult->fraudlabspro_status == 'APPROVE'){
$payment = new BluePayPayment_BP10Emu(
'your_bluepay_account_id',
'your_bluepay_secret_key',
'TEST' // Use TEST for development and LIVE for production
);
$payment->setCustomerInformation(
$_POST['firstName'],
$_POST['lastName'],
$_POST['address1'],
$_POST['address2'],
$_POST['state'],
$_POST['zipCode'],
$_POST['country']
);
$payment->setCCInformation(
$_POST['cardNumber'],
$_POST['cardMonthYear'],
$_POST['cardCVV']
);
$payment->sale($_POST['amount']);
$payment->process();
// Payment approved
if($payment->getStatus() == "APPROVED"){
// Capture the payment
$capture = new BluePayPayment_BP10Emu(
'your_bluepay_account_id',
'your_bluepay_secret_key',
'TEST' // Use TEST for development and LIVE for production
);
$capture->capture($payment->getTransID());
$capture->process();
}
}
// Transaction has been rejected by FraudLabs Pro based on your custom validation rules.
elseif($fraudResult->fraudlabspro_status == 'REJECT'){
/*
Do something here, try contact the customer for verification
*/
}
// Transaction is marked for a manual review by FraudLabs Pro based on your custom validation rules.
elseif($fraudResult->fraudlabspro_status == 'REVIEW'){
// Authorize this order with BluePay first
$payment = new BluePayPayment_BP10Emu(
'your_bluepay_account_id',
'your_bluepay_secret_key',
'TEST' // Use TEST for development and LIVE for production
);
$payment->setCustomerInformation(
$_POST['firstName'],
$_POST['lastName'],
$_POST['address1'],
$_POST['address2'],
$_POST['state'],
$_POST['zipCode'],
$_POST['country']
);
$payment->setCCInformation(
$_POST['cardNumber'],
$_POST['cardMonthYear'],
$_POST['cardCVV']
);
$payment->sale($_POST['amount']);
$payment->process();
// Payment approved
if($payment->getStatus() == "APPROVED"){
try{
// Initial MySQL connection
$db = new PDO('mysql:host=your_database_host;dbname=your_database_name;charset=utf8', 'your_database_user', 'your_database_password');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// Store the transaction information for decision making
$st = $db->prepare('INSERT INTO `fraudlabs_pro` VALUES (:flpId, :flpStatus, :bluepayId)');
$st->execute(array(
':flpId'=>$fraudResult->fraudlabspro_id,
':flpStatus'=>$fraudResult->fraudlabspro_status,
':bluepayId'=>$payment->getTransID()
));
}
catch(PDOException $e){
// MySQL error
die($e->getFile() . ':' . $e->getLine() . ' ' . $e->getMessage());
}
}
}
Now, we are going to create a callback page to receive the review action, APPROVE or REJECT, performed by the merchant.
Note: You need to configure the callback URL at the FraudLabs Pro merchant area->settings page. It has to be pointed to the location where you hosted this “fraudlabspro-callback.php” file. Below is the sample code for fraudlabspro-callback.php
$id = (isset($_POST['id'])) ? $_POST['id'] : '';
$action = (isset($_POST['action'])) ? $_POST['action'] : '';
if($id && in_array($action, array('APPROVE', 'REJECT'))){
try{
// Initial MySQL connection
$db = new PDO('mysql:host=your_database_host;dbname=your_database_name;charset=utf8', 'your_database_user', 'your_database_password');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// Get the BluePay Transaction ID
$st = $db->prepare('SELECT * FROM `fraudlabs_pro` WHERE `flp_transaction_id`=:flpId AND `flp_status`=\'REVIEW\'');
$st->execute(array(
':flpId'=>$id
));
if($st->rowCount() == 1){
$row = $st->fetch(PDO::FETCH_ASSOC);
require_once 'PATH_TO_BLUEPAY/lib/BluePayPayment_BP10Emu.php';
if($action == 'REJECT'){
// Merchant rejected the order. Void the transaction in BluePay
$void = new BluePayPayment_BP10Emu(
'your_bluepay_account_id',
'your_bluepay_secret_key',
'TEST' // Use TEST for development and LIVE for production
);
$void->void($row['bluepay_transaction_id']);
$void->process();
}
else{
// Merchant approved the order. Capture the transaction
$capture = new BluePayPayment_BP10Emu(
'your_bluepay_account_id',
'your_bluepay_secret_key',
'TEST' // Use TEST for development and LIVE for production
);
$capture->capture($row['bluepay_transaction_id']);
$capture->process();
}
// Update database
$st = $db->prepare('UPDATE `fraudlabs_pro` SET `flp_status`=:action WHERE `flp_transaction_id`=:flpId');
$st->execute(array(
':flpId'=>$id,
':action'=>$action
));
}
}
catch(PDOException $e){
// MySQL error
die($e->getFile() . ':' . $e->getLine() . ' ' . $e->getMessage());
}
}
If there is a need to issue a refund of a settled transaction, below is the sample code of how to accomplish it.
try{
// Initial MySQL connection
$db = new PDO('mysql:host=your_database_host;dbname=your_database_name;charset=utf8', 'your_database_user', 'your_database_password');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// Get the BluePay transaction ID based on the FraudLabs Pro ID
$st = $db->prepare('SELECT * FROM `fraudlabs_pro` WHERE `flp_transaction_id`=:flpId');
$st->execute(array(
':flpId'=>$_POST['flpId']
));
if($st->rowCount() == 1){
$row = $st->fetch(PDO::FETCH_ASSOC);
require_once 'PATH_TO_BLUEPAY/lib/BluePayPayment_BP10Emu.php';
$refund = new BluePayPayment_BP10Emu(
'your_bluepay_account_id',
'your_bluepay_secret_key',
'TEST' // Use TEST for development and LIVE for production
);
$refund->capture($row['bluepay_transaction_id']);
$refund->process();
// Update database
$st = $db->prepare('UPDATE `fraudlabs_pro` SET `flp_status`=\'REFUNDED\' WHERE `flp_transaction_id`=:flpId');
$st->execute(array(
':flpId'=>$_POST['flpId']
));
}
}
catch(PDOException $e){
// MySQL error
die($e->getFile() . ':' . $e->getLine() . ' ' . $e->getMessage());
}
