Getting started

Download the SDK

Download the archive with the latest version of the library and unpack it into your project.

Connect the files

Add it via Composer (path repository) or a plain require — instructions are in the README inside the archive.

Start the integration

Create a client with your API key and call methods for invoices, statuses and webhooks.

Usage example

checkout.php

use Crynova\CrynovaClient;

$crynova = new CrynovaClient('sk_live_your_api_key');

$invoice = $crynova->createInvoice([
    'currency'    => 'USD',          // fiat or crypto (BTC, USDT_TRC20, …)
    'amount'      => 49.90,
    'order_id'    => 'ORDER-1024',
    'description' => 'Pro plan — 1 month',
    'expires_in'  => 60,             // minutes
], idempotencyKey: 'ORDER-1024');

header('Location: ' . $invoice['checkout_url']);

// ── Verify a webhook ──────────────────────────────
use Crynova\Webhook;

$payload   = file_get_contents('php://input');
$signature = $_SERVER['HTTP_X_CRYNOVA_SIG'] ?? '';
$event     = Webhook::parse($payload, $signature, $webhookSecret);

if ($event['event'] === 'invoice.paid') {
    // fulfil the order
}
