Getting started

Creating a payment window V3

A simple example of how to create a payment window v3.

Read more about the fields here: https://manage.onpay.io/docs/paymentwindow_v3.html

<?php 
require_once 'vendor/autoload.php';

$paymentWindow = new \OnPay\API\PaymentWindow();
$paymentWindow->setGatewayId("YourGatewayId");
$paymentWindow->setSecret("YourSecret");
$paymentWindow->setCurrency("DKK");
$paymentWindow->setAmount("123400");
// Reference must be unique (eg. invoice number)
$paymentWindow->setReference("UniqieReferenceId");
$paymentWindow->setAcceptUrl("https://example.com/payment?success=1");
$paymentWindow->setDeclineUrl("https://example.com/payment?success=0");
$paymentWindow->setType("payment");
$paymentWindow->setDesign("DesignName");
// Force 3D secure
$paymentWindow->setSecureEnabled(true);
// Set payment method to be card
$paymentWindow->setMethod(\OnPay\API\PaymentWindow::METHOD_CARD);
// Enable testmode
$paymentWindow->setTestMode(true);
$paymentWindow->setLanguage("en");

// Add additional info
$paymentInfo = new \OnPay\API\PaymentWindow\PaymentInfo();
$paymentInfo->setName('Test Pærsån');
$paymentInfo->setEmail('emil@example.com');
// And so on, a lot more fields should be set if data available for it

$paymentWindow->setInfo($paymentInfo);

?>

<?php if($paymentWindow->isValid()) { ?>
<form method="post" action="<?php echo $paymentWindow->getActionUrl(); ?>" accept-charset="UTF-8">
    <?php
        foreach ($paymentWindow->getFormFields() as $key => $value) { ?>
            <input type="hidden" name="<?php echo $key;?>" value="<?php echo htmlspecialchars($value, ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML401, 'UTF-8');?>">
    <?php } ?>
    <input type="submit" value="Make payment">
</form>

<?php } else { ?>
    <h1>Payment window is not configured correct</h1>
<?php } ?>

You can create a transaction automatically when creating a new subscription using the following functions for the $paymentWindow variable:

$paymentWindow->setType("subscription");
$paymentWindow->setSubscriptionWithTransaction(true);

Verifying a payment from the acceptment page can easily be done as following:

$payment = new \OnPay\API\PaymentWindow();
$payment->setSecret('YourSecret');

if($payment->validatePayment($_GET)) {
    echo "Payment was successfull";
} else {
    echo "There was an error with the payment";
}

Using the API

A simple usage example looks like:

<?php

require_once __DIR__ . '/vendor/autoload.php';

class TokenStorage implements \OnPay\TokenStorageInterface {
    protected $token;
    protected $fileName;

    public function __construct($filename) {
        $this->fileName = $filename;
        if (file_exists($filename)) {
            $this->token = file_get_contents($this->fileName);
        }
    }

    public function getToken() {
        return $this->token;
    }

    public function saveToken($token) {
        $this->token = $token;
        file_put_contents($this->fileName, $token);
    }
}

// TODO: It is extremely important that the .token.bin file is not accessible from the internet.
// It gives complete API access to anyone that gets a hold of it, treat it like a database password!
$tokenStorage = new TokenStorage(__DIR__ . '/.token.bin');

$onPayAPI = new \OnPay\OnPayAPI($tokenStorage, [
    'client_id' => 'example.com', // It is recommended to set it to the domain name the integration resides on
    'redirect_uri' => 'http://localhost/onpay-php-sdk/example2.php?auth',
    'gateway_id' => '1234', // Should be set to the gateway id you are integrating with
]);

// Special handling if we are about to auth against the API
if (isset($_GET['auth'])) {
    if (!isset($_GET['code'])) {
        $authUrl = $onPayAPI->authorize();
        header('Location: ' . $authUrl);
    } else {
        $onPayAPI->finishAuthorize($_GET['code']);
        echo 'Authorized :tada:' . PHP_EOL;
    }
    exit;
}

// Check if we need to authenticate
if (!$onPayAPI->isAuthorized()) {
    echo 'Not authorized for the API! ' . PHP_EOL;
    echo '<a href=?auth>Click here to initiate authorization</a>' . PHP_EOL;
    exit;
}

// Execute API method
var_dump($onPayAPI->ping());
