1. Set up your special offers/sales
To set up special offers / sales, fill in the following fields:
- sale_price: the current, discount price of your products
- price: the regular price of your products
-
sale_price_start_date: required when "sale_price" is present.
Example: '2025-07-01' -
sale_price_end_date: required when "sale_price" is present.
Example: '2025-07-15'
2. Delivery cost
Complete the following attributes to set your shipping options:
-
"shipping": enter the shipping cost.
Expected format: country:region:service:price (ex: 'FR:-:Standard:4.90 EUR'; 'FR:-:Express:9.90 EUR')
Use ISO 3166 country codes (e.g., FR, ES, DE).
Use ISO 4217 currency codes (e.g., EUR, USD).
If no region applies, use - (dash).
Separate multiple shipping options with ; (semicolon).
3. Variation values
To correctly display products with variations, you need to define both the variant category (name) and its specific value using the following attributes:
-
"custom_variant1_category": Defines the type of variation.
Example: 'Fit_Type'
Rules: Free text, the naming must remain consistent across your catalogue (e.g., always use 'Fit_Type' for fit variations). -
"custom_variant1_option": Defines the value of that variation.
Example: 'Wide'
Rules: The value must match the declared category meaning (e.g., if the category is 'Fit_Type', the option could be 'Slim', 'Regular', or 'Wide').
 Multiple Variations
đź’ˇ If your products have multiple variation levels (e.g., size and colour), you can also use "custom_variant2_category" and "custom_variant2_option" following the same structure. Make sure you also complete the new "listing_has_variations" and "variant_dict" fields mapped to ChatGPT's new structure.
Manage your Exclusions
Configure exclusions to exclude the products you don't want to publish on this channel.
Parent products must be excluded from the feed, if your catalogue contains any.
