NAB Transact driver for the Omnipay PHP payment processing library

Omnipay is a framework agnostic, multi-gateway payment processing library for PHP. This package implements NAB Transact support for Omnipay.

Compatibility

• PHP ^7.2 || ^8.0
• omnipay/common:^3

Installation

Omnipay is installed via Composer. To install, simply require league/omnipay and sudiptpa/omnipay-nabtransact with Composer:

composer require league/omnipay sudiptpa/omnipay-nabtransact

Start Here: Choose the Right Integration Flow

• SecureXML (server-to-server):
  • Use NABTransact_SecureXML
  • Main methods: authorize(), purchase(), capture(), refund(), echoTest()
• DirectPost (redirect + callback):
  • Use NABTransact_DirectPost
  • Start methods: purchase() or authorize()
  • Callback methods: completePurchase(), completeAuthorize()
• DirectPost operations API (server-to-server):
  • Use capture(), refund(), void(), store(), createEMV3DSOrder()
• Hosted Payment Page:
  • Use NABTransact_HostedPayment
  • Methods: purchase(), completePurchase()
• UnionPay:
  • Use NABTransact_UnionPay
  • Methods: purchase(), completePurchase()

Basic Usage

The following gateways are provided by this package:

• NABTransact_DirectPost (NAB Transact Direct Post v2)
• NABTransact_SecureXML (NAB Transact SecurePay XML)
• NABTransact_HostedPayment (NAB Hosted Payment Page)
• NABTransact_UnionPay (UnionPay via NAB Transact)

NAB Transact SecureXML API

    use Omnipay\Omnipay;
    use Omnipay\Common\CreditCard;

    $gateway = Omnipay::create('NABTransact_SecureXML');
    $gateway->setMerchantId('XYZ0010');
    $gateway->setTransactionPassword('abcd1234');

    } else {
        echo sprintf('Transaction %s failed: %s', $response->getTransactionReference(), $response->getMessage());
    }

For general usage instructions, please see the main Omnipay repository.

Framework-Agnostic Transport Option

Omnipay support remains the default behavior. SecureXML requests can now also use a framework-agnostic cURL transport:

use Omnipay\NABTransact\Transport\CurlTransport;

$request = $gateway->purchase([
    'amount' => '10.00',
    'transactionId' => 'ORDER-1000',
    'card' => $card,
]);

$request->setTransport(new CurlTransport());
$response = $request->send();

DirectPost server-to-server operations (capture, refund, void, createEMV3DSOrder) can use the same transport injection pattern.

See ARCHITECTURE.md for design details and extension points.
