PHP SDK

Use the official PonponPay PHP SDK to create orders, query status, and verify webhook callbacks in Laravel, WordPress, WHMCS, or any custom PHP application.

If you need raw HTTP endpoints instead of the SDK wrapper, see the API Key guide.

Installation

composer require ponponpay/php-sdk

Initialize the client

use PonponPay\PonponPay;

$ponponpay = new PonponPay('your-api-key', [
    'api_url' => 'https://api.ponponpay.com',
    'timeout' => 30,
]);

Create an order

$order = $ponponpay->createOrder([
    'mch_order_id' => 'ORDER_' . time(),
    'currency'     => 'USDT',
    'network'      => 'tron',
    'amount'       => 10.00,
    'notify_url'   => 'https://your-site.com/webhook.php',
    'redirect_url' => 'https://your-site.com/success',
]);

echo $order->tradeId;
echo $order->paymentUrl;
echo $order->address;

Query an order

$order = $ponponpay->getOrderByTradeId('T20240101120000123456');

echo $order->status;
echo $order->txHash;

Verify webhook callbacks

The SDK includes HMAC-SHA256 verification with timestamp window checks and nonce-based replay protection. For the full security model, also review Webhook Security.

use PonponPay\PonponPay;
use PonponPay\WebhookHandler;
use PonponPay\Exception\SignatureException;

$ponponpay = new PonponPay('your-api-key');

try {
    $data = $ponponpay->webhook()->handle();
    $status = WebhookHandler::resolveStatus($data);

    if ($status === 'paid') {
        // update your business order here
    }

    http_response_code(200);
    echo 'OK';
} catch (SignatureException $e) {
    http_response_code($e->getHttpStatus());
    echo $e->getMessage();
}
