Klaviyo Signals JS in Additional Scripts

// Klaviyo "Signals" onsite identify/track script tags injected via
// Additional Scripts stop running Aug 26. The sandbox-correct replacement is
// the same Klaviyo Client Events API call as the Placed Order template,
// fired at the point identity is known (checkout_contact_info_submitted) so
// the profile identify happens as early in checkout as the old Signals
// script did, not only at completion.
analytics.subscribe('checkout_contact_info_submitted', (event) => {
  const { checkout } = event.data;
  if (!checkout || !checkout.email) return;

  fetch('https://a.klaviyo.com/client/profiles/?company_id=KLAVIYO_PUBLIC_API_KEY', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json', revision: '2024-10-15' },
    keepalive: true,
    body: JSON.stringify({
      data: { type: 'profile', attributes: { email: checkout.email } },
    }),
  });
});
