const stripe = new PaySync.Stripe(process.env.STRIPE_SECRET_KEY!);

const signatureHeader = context.req.header("Stripe-Signature");
if (!signatureHeader) throw new Error("No Signature");

const webhookPayload = {
  signatureHeader: signatureHeader,
  webhookSecret: process.env.STRIPE_WEBHOOK_SECRET!,
  requestBody: await context.req.text(),
};

const webhookEvent = await stripe.validateWebhookSignature(webhookPayload);

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

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