Give your customers a Lab Results link that's always current.
Paste this snippet once on your product page. It shows the live certificate for that barcode, kept current by the brand — and if a product is ever recalled, the notice reaches every store carrying that barcode the same day. No re-uploading PDFs, nothing to keep track of. Free for retailers.
One rule: paste the snippet into a custom-HTML / code block on your product page — not a data field like a Shopify metafield. A data field stores text and strips out scripts; a code block actually renders it.
The snippet
Unlike a PDF link you paste once — or a QR code frozen on last year's batch — this link updates itself. When the brand re-tests, every store shows the new COA the same day, with nothing to re-upload.
In your Catalog, click Copy embed on a product. You get this, with the barcode already filled in:
<script src="https://rdrelay.com/embed.js" async></script> <span data-rd-relay-labresults data-barcode="012345678905"></span>
It renders a live “↗ Lab Results” link that always points to the current certificate for that product.
Where it goes, by platform
- Shopify. Online Store → Customize → open your product template → Add section/block → Custom Liquid → paste it there. Not a metafield — metafields strip scripts, which is the validation error you hit.
- WooCommerce / WordPress. A Custom HTML block on the product template, or a code-snippet plugin.
- Wix. Add → Embed & Social → Embed HTML / Custom Code.
- Squarespace. A Code block on the product page.
- BigCommerce. The HTML / custom-content area of the product template.
- Custom-built site. Straight into your product page template.
Do it once for your whole catalog
The copied snippet has a fixed barcode, so it only works on that one product — perfect for a test. To cover every product automatically, put it in your product template once and feed the barcode from the product data. On Shopify (in a Custom Liquid block):
<span data-rd-relay-labresults
data-barcode="{{ product.selected_or_first_available_variant.barcode }}"></span>
<script src="https://rdrelay.com/embed.js" async></script>Prefer no JavaScript? This pure-Liquid version renders the same link server-side, even if a theme blocks scripts:
{%- assign bc = product.selected_or_first_available_variant.barcode -%}
{%- if bc != blank -%}
<a href="https://rdrelay.com/c/{{ bc }}" target="_blank" rel="noopener"
style="display:inline-flex;align-items:center;gap:6px;font-weight:600;color:#1F2A1C;text-decoration:none;">
<span aria-hidden="true">↗</span> Lab Results
</a>
{%- endif -%}One requirement either way: the product's barcode must match the barcode the brand registered on rd Relay — that is what the link resolves against.
Not the one who installs code?
Send this page to your web person — the whole install is one paste. BREZ, Cypress Hemp, Sunrise Hemp, Cold Walk, and Utokia already publish on rd Relay (see the live brand list), and it runs in our own Baton Rouge stores first — this is the same embed we use.
Brand or distributor? It's the same record on your side — one barcode, one record, every store current.
