{%- assign product-id = "variant-id" -%}{%- comment -%}The format of the product IDs in the feed. 3 accepted values "sku" (SKU of the variant e.g. aga-012), "variant-id" (variant ID e.g. 21283160948841), or "product-id_variant-id" (product ID underscore then variant ID e.g. 28541777444969_21283160948841).{%- endcomment -%}
{%- assign product-id-prefix = "" -%}{%- comment -%}Prefix to product-id. Leave blank if there's no prefix. This is likely needed if product-id_variant-id is selected so 123456_789012 becomes shopify_AU_28541777444969_21283160948841.{%- endcomment -%}
{%- assign price-decimal-fs = false -%}{%- comment -%}If the decimal separator is a full stop like in USD and AUD currencies, set to true. If it is a comma like in some European countries, set to false.{%- endcomment -%}
{%- comment -%}Change dimension1, dimension2, and dimension3 on line 15 to match your custom dimension number in Google Analytics.{%- endcomment -%}
