import {
  createCheckoutVerification,
  pollCheckoutVerification,
} from '@union-networks/verification';

const checkout = await createCheckoutVerification(
  {
    serviceId: 'example-shop',
    assertionJws,
    requiredChecks: ['age_over_18'],
    restrictedResourceIds: ['wine-001'],
    ttlSeconds: 120,
  },
  { issuerBaseUrl: 'https://issuer.egress.live' },
);

if (checkout.requiresVerification && checkout.verification) {
  renderQr(checkout.verification.qrPayload);
  const finalCheckout = await pollCheckoutVerification(
    {
      checkoutId: checkout.checkout.checkoutId,
      serviceId: 'example-shop',
      assertionJws,
    },
    { issuerBaseUrl: 'https://issuer.egress.live' },
