Description: This tutorial demonstrates how to integrate FraudLabs Pro fraud detection service into Paysafe payment process. We show you the step-by-step instructions using the PHP language in the below section.
Using PHP
Create a new table to store the transaction value of FraudLabs Pro and Paysafe 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, `paysafe_transaction_id` VARCHAR(30) NOT NULL, `paysafe_amount` DECIMAL(12,2) NOT NULL, `paysafe_settlement_id` VARCHAR(30) NOT NULL, PRIMARY KEY (`flp_transaction_id`) ) COLLATE='utf8_general_ci' ENGINE=MyISAM;

Integrate FraudLabs Pro fraud detection logic with your Paysafe 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 Paysafe library
require_once('../source/paysafe.php');
use Paysafe\PaysafeApiClient;
use Paysafe\Environment;
use Paysafe\CardPayments\Authorization;
$paysafeApiKeyId = 'your_paysafe_api_key_id';
$paysafeApiKeySecret = 'your_paysafe_api_key_secret';
$paysafeAccountNumber = 'your_paysafe_api_account_number';
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['number'],
],
'billing' => [
'country' => $_POST['country'],
],
];
// Sends the order details to FraudLabs Pro
$fraudResult = FraudLabsPro\Order::validate($orderDetails);
// This transaction is legitimate, let's submit to Paysafe
if ($fraudResult->fraudlabspro_status == 'APPROVE') {
$client = new PaysafeApiClient($paysafeApiKeyId, $paysafeApiKeySecret, Environment::TEST, $paysafeAccountNumber);
$auth = $client->cardPaymentService()->authorize(new Authorization(array(
'merchantRefNum' => $_POST['merchant_ref_num'],
'amount' => $_POST['amount'],
'settleWithAuth' => false,
'card' => array(
'cardNum' => $_POST['number']
)
)));
}
// Transaction has been rejected by FraudLabs Pro based on your custom validation rules.
elseif ($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') {
$client = new PaysafeApiClient($paysafeApiKeyId, $paysafeApiKeySecret, Environment::TEST, $paysafeAccountNumber);
try {
$auth = $client->cardPaymentService()->authorize(new Authorization(array(
'merchantRefNum' => $_POST['merchant_ref_num'],
'amount' => $_POST['amount'],
'settleWithAuth' => true,
'card' => array(
'cardNum' => $_POST['number']
)
)));
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` (flp_transaction_id, flp_status, paysafe_transaction_id, paysafe_amount) VALUES (:flpId, :flpStatus, :paysafeId, :paysafeAmount)');
$st->execute(array(
':flpId'=>$fraudResult->fraudlabspro_id,
':flpStatus'=>$fraudResult->fraudlabspro_status,
':paysafeId'=>$auth->id,
':paysafeAmount'=>$_POST['amount']
));
}
catch(PDOException $e){
// MySQL error
die($e->getFile() . ':' . $e->getLine() . ' ' . $e->getMessage());
}
} catch (Paysafe\PaysafeException $e) {
var_dump($e->getMessage());
if ($e->fieldErrors) {
var_dump($e->fieldErrors);
}
if ($e->links) {
var_dump($e->links);
}
}
}
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.
// Include Paysafe library
require_once('../source/paysafe.php');
use Paysafe\PaysafeApiClient;
use Paysafe\Environment;
use Paysafe\CardPayments\Authorization;
$id = (isset($_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 Paysafe 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);
$paysafeApiKeyId = 'your_paysafe_api_key_id';
$paysafeApiKeySecret = 'your_paysafe_api_key_secret';
$paysafeAccountNumber = 'your_paysafe_api_account_number';
$client = new PaysafeApiClient($paysafeApiKeyId, $paysafeApiKeySecret, Environment::TEST, $paysafeAccountNumber);
$authorizationId = $row['paysafe_transaction_id'];
if($action == 'REJECT'){
// Merchant rejected the order. Void the transaction in Paysafe
try {
$authReversal = new AuthorizationReversal(array(
'merchantRefNum' => $_POST['merchant_ref_num'],
'amount' => $row['paysafe_amount'],
'authorizationID' => $authorizationId
));
$client->cardPaymentService()->reverseAuth($authReversal);
// 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 (Paysafe\PaysafeException $e) {
// This will print the detailed information on the exception.
echo $e->getMessage();
}
}
else{
// Merchant approved the order. Submit for settlement
try {
$response = $client->cardPaymentService()->settlement(new Settlement(array(
'merchantRefNum' => $_POST['merchant_ref_num'],
'authorizationID' => $authorizationId
)));
$settlementID = $response->id;
// Update database
$st = $db->prepare('UPDATE `fraudlabs_pro` SET `flp_status`=:action, `paysafe_settlement_id`=:settlementId WHERE `flp_transaction_id`=:flpId');
$st->execute(array(
':flpId'=>$id,
':settlementId'=>$settlementID,
':action'=>$action
));
} catch (Paysafe\PaysafeException $e) {
// This will print the detailed information on the exception.
echo $e->getMessage();
}
}
}
}
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.
// Include Paysafe library
require_once('../source/paysafe.php');
use Paysafe\PaysafeApiClient;
use Paysafe\Environment;
use Paysafe\CardPayments\Authorization;
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 Paysafe 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);
$paysafeApiKeyId = 'your_paysafe_api_key_id';
$paysafeApiKeySecret = 'your_paysafe_api_key_secret';
$paysafeAccountNumber = 'your_paysafe_api_account_number';
$client = new PaysafeApiClient($paysafeApiKeyId, $paysafeApiKeySecret, Environment::TEST, $paysafeAccountNumber);
$settlementId = $row['paysafe_settlement_id'];
try {
// Process a refund
$response = $client->cardPaymentService()->refund(new Refund(array(
'merchantRefNum' => $_POST['merchant_ref_num'],
'settlementID' => $settlementId
)));
// Update database
$st = $db->prepare('UPDATE `fraudlabs_pro` SET `flp_status`=\'REFUNDED\' WHERE `flp_transaction_id`=:flpId');
$st->execute(array(
':flpId'=>$_POST['flpId']
));
} catch (Paysafe\PaysafeException $e) {
// This will print the detailed information on the exception.
echo $e->getMessage();
}
}
}
catch(PDOException $e){
// MySQL error
die($e->getFile() . ':' . $e->getLine() . ' ' . $e->getMessage());
}
