Certificate Metafields

When a valuation generates a certificate, we write the certificate URL back onto the matching Shopify product as a metafield. You can then surface it on the storefront.

What we write

Namespace jewel_value, key certificate, type url, value the public certificate URL. We also write jewel_value.certificate_generated_at (datetime).

Showing on the product page

In your theme:

{% if product.metafields.jewel_value.certificate %}
  <a href="{{ product.metafields.jewel_value.certificate }}" target="_blank">
    Download Valuation Certificate
  </a>
{% endif %}

Variant-level certificates

For products with size variants where each variant has its own valuation, we write metafields per variant rather than per product. The Liquid above becomes variant.metafields.jewel_value.certificate.

Customer notifications

If you've enabled the Email certificate to customer option, the certificate is also sent in the order confirmation email and the standard Shopify customer-account view.

Disabling

If you don't want metafields written, switch off Sync to product metafields in Settings > Integrations > Shopify. Existing metafields are not removed; new valuations stop writing them.
