The OpenPayU PHP library provides integration access to the REST API 2.1
PHP >= 5.3 with extensions cURL and hash
Full implementation guide: English, Polish.
To process operations such as:
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:
In both cases you will find orderId using this statement: $response->getResponse()->orderId
.
To install with Composer, simply add the requirement to your composer.json file:
{
"require" : {
"openpayu/openpayu" : "2.3.*"
}
}
Then install by running
composer.phar install
Obtain the latest version of openpayu_php SDK with:
git clone https://github.com/PayU/openpayu_php.git
If you are using Composer use autoload functionality:
include "vendor/autoload.php";
Or simply add this lines anywhere in your application:
require_once 'lib/openpayu.php';
require_once realpath(dirname(__FILE__)) . '/../../config.php';
Important: SDK works only with 'REST API' (Checkout) points of sales (POS). If you do not already have PayU merchant account, please register in Production or please register in Sandbox
Example "Configuration keys" from Merchant Panel
To configure OpenPayU environment you must provide a set of mandatory data in config.php file.
For production environment:
//set Production Environment
OpenPayU_Configuration::setEnvironment('secure');
//set POS ID and Second MD5 Key (from merchant admin panel)
OpenPayU_Configuration::setMerchantPosId('145227');
OpenPayU_Configuration::setSignatureKey('13a980d4f851f3d9a1cfc792fb1f5e50');
//set Oauth Client Id and Oauth Client Secret (from merchant admin panel)
OpenPayU_Configuration::setOauthClientId('145227');
OpenPayU_Configuration::setOauthClientSecret('12f071174cb7eb79d4aac5bc2f07563f');
For sandbox environment:
//set Sandbox Environment
OpenPayU_Configuration::setEnvironment('sandbox');
//set POS ID and Second MD5 Key (from merchant admin panel)
OpenPayU_Configuration::setMerchantPosId('300046');
OpenPayU_Configuration::setSignatureKey('0c017495773278c50c7b35434017b2ca');
//set Oauth Client Id and Oauth Client Secret (from merchant admin panel)
OpenPayU_Configuration::setOauthClientId('300046');
OpenPayU_Configuration::setOauthClientSecret('c8d4b7ac61758704f38ed5564d8c0ae0');
If you want to use sandbox environment, register at this link https://secure.snd.payu.com/cp/register?lang=en
SDK supports two PayU OAuth grant types: client_credentials
and trusted_merchant
. Default is client_credentials
.
If you want to change grant type use:
OpenPayU_Configuration::setOauthGrantType('grant_type');
grant_type can be one of the following OauthGrantType::CLIENT_CREDENTIAL
or OauthGrantType::TRUSTED_MERCHANT
Parameters needed for client_credentials
//set Oauth Client Id and Oauth Client Secret (from merchant admin panel)
OpenPayU_Configuration::setOauthClientId('300046');
OpenPayU_Configuration::setOauthClientSecret('c8d4b7ac61758704f38ed5564d8c0ae0');
Parameters needed for trusted_merchant
//set Oauth Client Id and Oauth Client Secret (from merchant admin panel)
OpenPayU_Configuration::setOauthClientId('clent_id');
OpenPayU_Configuration::setOauthClientSecret('clent_secret');
//set Oauth Email and Oauth Ext Customer Id
OpenPayU_Configuration::setOauthEmail('email');
OpenPayU_Configuration::setOauthExtCustomerId('ext_customer_id');
OpenPayU_Configuration::setProxyHost('address');
OpenPayU_Configuration::setProxyPort(8080);
OpenPayU_Configuration::setProxyUser('user');
OpenPayU_Configuration::setProxyPassword('password');
OpenPayU library automatically stores OAuth authentication data in the Cache.
OpenPayU library has two classes implemented to manage the Cache:
OauthCacheFile
- data is stored in the file system.
This is a default and automatic Cache method which stores the data in lib/Cache
folder.
ATTENTION: for security reasons it is recommended to change the Cache folder, so it would not be accessible from the web browser.
Configuration:
OpenPayU_Configuration::setOauthTokenCache(new OauthCacheFile($directory));
$directory
- absolute path to the data folder; if the parameter is missing, the folder is lib/Cache
OauthCacheMemcached
- data is stored in Memcached
This method requires Memcached (https://memcached.org/) to be installed on the server along with Memcached PHP module (http://php.net/manual/en/book.memcached.php)
Configuration:
OpenPayU_Configuration::setOauthTokenCache(new OauthCacheMemcached($host, $port, $weight));
$host
- Memcached server address - localhost
by default
$port
- Memcached server port - 11211
by default
$weight
- Memcached server priority - 0
by default
It is possible to implement another method to manage cache. In such a case it needs to implement OauthCacheInterface
Remember: All keys in "order array" must be in lowercase.
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/'; //customer will be redirected to this page after successfull payment
$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'; //must be unique!
$order['products'][0]['name'] = 'Product1';
$order['products'][0]['unitPrice'] = 1000;
$order['products'][0]['quantity'] = 1;
$order['products'][1]['name'] = 'Product2';
$order['products'][1]['unitPrice'] = 2200;
$order['products'][1]['quantity'] = 1;
//optional section buyer
$order['buyer']['email'] = 'dd@ddd.pl';
$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.
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 orderId
File with working example: examples/v2/order/OrderTransactionRetrieve.php
You can retrieve transactions for order by its PayU order_id
$response = OpenPayU_Order::retrieveTransaction('Z963D5JQR2230925GUEST000P01'); //as parameter use orderId
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 orderId
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);
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');
$data = trim($body);
$response = OpenPayU_Order::consumeNotification($data);
$response->getResponse()->order->status; //NEW PENDING CANCELED REJECTED COMPLETED WAITING_FOR_CONFIRMATION
header("HTTP/1.1 200 OK");
}
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
'ext-customer-id', // External submerchant ID, required only for marketplace
'ext-refund-id' // External refund ID, required only for marketplace
);
File with working example: examples/v2/retrieve/RetrievePaymethods.php
You can retrieve pay methods from POS
$response = OpenPayU_Retrieve::payMethods();
You can add optional parameter lang
to payMethods()
$response = OpenPayU_Retrieve::payMethods('en');
File with working example: examples/v2/token/TokenDelete.php
You can delete user's card token.
Token deletion is possible only for trusted_merchant
grant type.

You can retrieve shop data.
$shop = OpenPayU_Shop::get(
'PUBLIC_SHOP_ID' // Shop ID from Merchant Panel
);
