Documentation

Full implementation guide [English][Polish].

To process operations such as:

• order status update
• order retrieve
• order cancel

You will need to provide a parameter called orderId. The value of orderId is your order identifier that is set by PayU Payment system, and it's used to invoke remote methods.

There are two ways to get orderId.

1. Inside the received notification message from PayU Payment System as a result of payment.
2. In the response from method OpenPayU_Order::create.

In both cases you will find orderId using this statement: $response->getResponse()->orderId.

Installation

Composer

To install with Composer, simply add the requirement to your composer.json file:

{
  "require" : {
    "openpayu/openpayu" : "2.0.*"
  }
}

Then install by running

composer.phar install

Manual installation

Obtain the latest version of openpayu_php SDK with:

git clone https://github.com/PayU/openpayu_php.git

Getting started

If you are using Composer:

include "vendor/autoload.php";

Or simply add this line anywhere in your application:

    require_once 'lib/openpayu.php';
    require_once realpath(dirname(__FILE__)) . '/../../config.php';

##Configure To configure OpenPayU environment you must provide a set of mandatory data in config.php file:

    OpenPayU_Configuration::setEnvironment('secure');
    OpenPayU_Configuration::setMerchantPosId('145227'); // POS ID (Checkout)
    OpenPayU_Configuration::setSignatureKey('13a980d4f851f3d9a1cfc792fb1f5e50'); //Second MD5 key. You will find it in admin panel.

##Usage

Remember: All keys in "order array" must be in lowercase.

###Creating order using REST API

File with working example: examples/v2/order/OrderCreate.php

To create an order using REST API in back-end you must provide an Array with order data:

in your controller

    $order['continueUrl'] = 'http://localhost/';
    $order['notifyUrl'] = 'http://localhost/';
    $order['customerIp'] = $_SERVER['REMOTE_ADDR'];
    $order['merchantPosId'] = OpenPayU_Configuration::getMerchantPosId();
    $order['description'] = 'New order';
    $order['currencyCode'] = 'PLN';
    $order['totalAmount'] = 3200;
    $order['extOrderId'] = '1342';

    $order['products']['products'][0]['name'] = 'Product1';
    $order['products']['products'][0]['unitPrice'] = 1000;
    $order['products']['products'][0]['quantity'] = 1;

    $order['products']['products'][1]['name'] = 'Product2';
    $order['products']['products'][1]['unitPrice'] = 2200;
    $order['products']['products'][1]['quantity'] = 1;

    $order['buyer']['email'] = '[email protected]';
    $order['buyer']['phone'] = '123123123';
    $order['buyer']['firstName'] = 'Jan';
    $order['buyer']['lastName'] = 'Kowalski';

    $response = OpenPayU_Order::create($order);

    header('Location:'.$response->getResponse()->redirectUri); //You must redirect your client to PayU payment summary page.

###Retrieving order from OpenPayU

File with working example: examples/v2/order/OrderRetrieve.php

You can retrieve order by its PayU order_id

    $response = OpenPayU_Order::retrieve('Z963D5JQR2230925GUEST000P01'); //as parameter use ORDER_ID

###Cancelling order

File with working example: examples/v2/order/OrderCancel.php

You can cancel order by its PayU order_id

    $response = OpenPayU_Order::cancel('Z963D5JQR2230925GUEST000P01'); //as parameter use ORDER_ID

###Updating order status

File with working example: examples/v2/order/OrderStatusUpdate.php

You can update order status to accept order.

    $status_update = array(
        "orderId" => 'Z963D5JQR2230925GUEST000P01', //as value use ORDER_ID
        "orderStatus" => 'COMPLETED'
    );

    $response = OpenPayU_Order::statusUpdate($status_update);

###Handling notifications from PayU

File with working example: examples/v2/order/OrderNotify.php

PayU sends requests to your application when order status changes

    if ($_SERVER['REQUEST_METHOD'] == 'POST') {
        $body = file_get_contents('php://input');
        $data = stripslashes(trim($body));

        $response = OpenPayU_Order::consumeNotification($data);
        $response->Response->Status; //NEW PENDING CANCELLED REJECTED COMPLETED WAITING_FOR_CONFIRMATION

        $rsp = OpenPayU::buildOrderNotifyResponse($response->Response->Order->OrderId);

        //you should response to PayU with special structure (OrderNotifyResponse)
        header("Content-Type: application/json");
        echo $rsp;
    }

###Refund money

File with working example: examples/v2/refund/RefundCreate.php

You can create refund to refund money on buyer account

    $refund = OpenPayU_Refund::create(
        'Z963D5JQR2230925GUEST000P01', //as a value use ORDER_ID
        'Money refund', //Description - required
        '100' //Amount - If not provided, returns whole transaction, optional
    );
