ChatGPT Product Feeds for Shopify: Fields and Variants

Direct answer

A ChatGPT product feed is a structured catalog input for product discovery. In OpenAI’s current stable file-upload specification, submit one row per purchasable item or variant. Each row needs a stable item ID plus factual title, description, destination URL, brand, seller name, image URL, price, and availability. Variants need separate item IDs, a shared group ID, and their selected option values.

For Shopify, map those fields from the current product and variant records, then reconcile every row against the public destination page. A feed can make catalog facts available for discovery; acceptance does not guarantee that ChatGPT will show, cite, or recommend a product. See OpenAI’s official product feed specification and commerce setup guide.

A feed is not another product description

OpenAI’s commerce guide describes sharing a structured product feed as the starting point for product discovery integration. The feed provides catalog records that ChatGPT can use to index products, understand attributes, and present current shopping information.

A feed is designed for precise fields, not page layout. It may carry:

• stable item identity
• title and description
• destination URL
• images
• brand and identifiers
• price and availability
• variant attributes

Required discovery fields to map

OpenAI’s stable schema currently lists nine required fields for each discovery row:

Feed field	Shopify source to verify	Important constraint
item_id	variant ID or another durable catalog key	unique per item or variant; never recycle it for a different item
title	product title plus selected options where relevant	factual and concise
description	product or variant description	plain text; no invented claims
url	public product destination	stable and variant-selected when possible
brand	product vendor or verified brand field	use the real brand, not a placeholder
seller_name	merchant identity	use the real seller name
image_url	current product or variant image	direct image URL showing the item
price	current variant price and currency	major currency units, such as 89.00 CAD
availability	current sellable state	use a supported value; use unknown when stock is genuinely unavailable

This is a mapping checklist, not a claim that every Shopify store has an enabled direct feed. Feed setup, supported markets, Ads, and checkout have separate requirements and must be confirmed with OpenAI.

The Shopify source still matters

For a Shopify merchant, the product record is often the operational source for title, description, variants, inventory, price, and images. Shopify Catalog or another integration may transform that data for an AI channel.

The store owner should ask:

1. Which Shopify fields supply the feed?
2. How often do price and stock update?
3. Which market and currency does each record represent?
4. How are variants separated?
5. Where can rejected or ineligible records be seen?

Stable identity prevents catalog drift

An item_id should remain stable for the same purchasable item. GTIN and MPN can help identify products when legitimately assigned. A variant that changes item ID on every export can lose continuity.

The destination URL should resolve successfully to the intended public product. Redirecting every market to a generic homepage weakens the connection between the feed record and product evidence.

Represent Shopify variants as separate rows

Do not flatten every size or color into one generic record when price, availability, URL, or image differs. OpenAI’s schema says each variant row should have its own item_id, share a group_id, set listing_has_variations to true, and provide its selected options in variant_dict. Each row carries its own commercial facts.

{
  "item_id": "gid-shopify-variant-456",
  "group_id": "gid-shopify-product-123",
  "listing_has_variations": true,
  "variant_dict": { "Color": "Black", "Size": "10" },
  "title": "Trail shoe — Black, size 10",
  "url": "https://example.com/products/trail-shoe?variant=456",
  "price": "89.00 CAD",
  "availability": "in_stock"
}

This abbreviated example shows the variant relationship; it omits other required fields and is not a complete upload row. To expose the same selection accurately on a theme, use the Shopify product and variant Liquid guide.

Use a three-source reconciliation table

For one SKU, compare:

Fact	Shopify admin	Public page	Feed record
item identity	SKU and variant	selected option	stable item_id
title	current	current	accurate and concise
price	CAD 89	CAD 89	CAD 89
availability	available	add to cart works	in stock
URL	product handle	canonical URL	same destination

Descriptions can be formatted differently, but the commercial facts must agree.

What not to do

Do not add invented keywords, fake identifiers, unsupported claims, or a dozen near-duplicate records. Do not assume feed acceptance guarantees a ChatGPT recommendation. Product eligibility and final selection remain platform decisions.

For broader context, read Webpages, product feeds and Shopify Catalog. For an operational check, follow the Shopify price versus page JSON-LD guide and add the feed row as the third comparison source.
