Topic summary

A developer is working on a Shopify theme extension and needs to find a product using its global ID (GID) format: gid://shopify/Product/8789. They want to know how to locate this product in Liquid and convert it properly.

Response provided:

  • The solution depends on which page the product ID is needed
  • On Product Pages: Access directly using {{ product.id }}
  • On Collection Pages: Loop through products:
    {% for c in collection.products %}
  {% assign pId = c.id %}
  {{ pId }}
{% endfor %}

On which page you need to find the product ID?

Example:-

  1. On Product Page
    You get directly by using {{ product.id }}

  2. On Collection Page
    Here you will get by looping through
    f{% for c in collection.products %}
    {% assign pId = c.id %}
    {{ pId }}
    {% endfor %}
