Integrations
Accept crypto payments in OpenCart
OpenCart payment extensions follow a fixed structure (a controller, a model and a template under extension/crybit/payment). The controller creates a CryBit invoice for the order total and sends the customer to the payment page.
Confirm handler
PHP (extension/crybit/payment/crybit.php)
public function confirm() {
$order = $this->model_checkout_order->getOrder($this->session->data['order_id']);
$ch = curl_init('https://api.crybit.net/api/v1/payments');
curl_setopt_array($ch, [
CURLOPT_POST => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => ['X-Public-Key: ' . $this->config->get('crybit_public_key'), 'X-Private-Key: ' . $this->config->get('crybit_private_key'), 'Content-Type: application/json'],
CURLOPT_POSTFIELDS => json_encode([
'amount' => (float) $order['total'],
'currency' => $order['currency_code'],
'order_id' => (string) $order['order_id'],
'return_url' => $this->url->link('checkout.success'),
]),
]);
$inv = json_decode(curl_exec($ch), true);
$this->response->redirect($inv['callback_url']);
}Order status on payment
A small controller behind the CryBit webhook verifies the signature and calls addOrderHistory() with your “processing” status id, matched by order_id.
FAQ
Is there an extension in the OpenCart Marketplace?
Not yet — the controller above is the direct path today, built on the same public API as every other integration.
