Accept crypto payments on Shopify

How it fits into Shopify

Add a manual payment method named “Crypto / USDT” in Settings → Payments → Manual payment methods. When an order comes in with that method, your backend (a small Shopify app, a Flow automation, or an order-webhook handler) calls the CryBit API to create an invoice and sends the customer the payment link by email or on the order status page.

Shopify Plus stores with checkout extensibility can instead call the API from a checkout UI extension and redirect straight to the CryBit payment page, skipping the manual-method step.

Create the invoice on order creation

app.post('/webhooks/orders-create', verifyShopifyHmac, async (req, res) => {
  const order = req.body
  const inv = await fetch('https://api.crybit.net/api/v1/payments', {
    method: 'POST',
    headers: {
      'X-Public-Key': process.env.CRYBIT_PUBLIC_KEY,
      'X-Private-Key': process.env.CRYBIT_PRIVATE_KEY,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      amount: order.total_price,
      currency: order.currency,
      order_id: String(order.id),
      purpose: 'Shopify order #' + order.order_number,
      return_url: order.order_status_url,
    }),
  }).then(r => r.json())
  // отправьте письмо/уведомление со ссылкой inv.callback_url
  res.sendStatus(200)
})

Confirm the order by webhook

Point the CryBit webhook (merchant settings, event payment.paid) at an endpoint that marks the Shopify order as paid via the Shopify Admin API (POST /orders/{id}/transactions.json with kind capture), keyed by your order_id.
