Shopify

Requirements

An app in your store with scopes read_products, write_products (to write anchor prices to metafields) and optionally write_online_store_pages (for the Cjenici page).

Path A — an existing custom app (Admin API token)

If your store already has a custom app (Settings → Apps and sales channels → Develop apps), copy the Admin API access token (shpat_…) and, for instant updates, the API secret key.

Path B — a new app from the Dev Dashboard

1. Open the Shopify Dev Dashboard → Create app.
2. Enable the scopes above in the app version and release it.
3. Install the app on your store.
4. Copy the Client ID and Client secret from the app settings.

With Client ID and secret, Sidro obtains access tokens itself (client credentials).

Connecting in Sidro

Data sources → Shopify: yourstore.myshopify.com, the token or Client ID + secret, and Write anchor prices to metafields. Sidro then reads all variants, writes custom.sidrena_cijena (money) and custom.sidrena_datum (date) to every variant and, with a client secret, registers a products/update webhook.

Theme display (Liquid)

{%- assign v = product.selected_or_first_available_variant -%}
{%- if v.metafields.custom.sidrena_cijena -%}
  <p class="sidrena-cijena" data-sidro-sifra="{{ v.sku }}">
    Sidrena cijena ({{ v.metafields.custom.sidrena_datum.value | date: '%-d. %-m. %Y.' }}):
    <strong>{{ v.metafields.custom.sidrena_cijena.value | money }}</strong>
  </p>
{%- endif -%}

For themes that switch variants without reloading, add the widget too.
