const webhookEvent = await stripe.verifySignature({
  signature: sign,
  secret: "PUT YOUR WEBHOOK SECRET HERE",
  body: await c.req.text(),
});

if ("error" in webhookEvent) throw new Error(webhookEvent.error.message);

switch (webhookEvent.event.type) {
  case "checkout.session.async_payment_succeeded":
    break;

  default:
    break;
}

// LemonSqueezy
