The OpenAI product feed spec, explained

Every required field, the control flags, and the mistakes that quietly cost you eligibility.

The product feed is the core artifact of ChatGPT Shopping — the file OpenAI reads to know your products, prices and stock. Here is the specification in practical form.

File format
UTF-8; Parquet preferred, gzipped JSONL, CSV or TSV accepted; a stable filename overwritten with each daily snapshot. One header row, lowercase_underscore field names, one product variant per row. Delivered by SFTP or the feeds API after approval — OpenAI does not pull from a URL.
Required fields, every row
item_id (stable, ≤100 chars) · title (≤150, plain text) · description (≤5,000, plain text, no HTML) · url (must resolve 200) · image_url (JPEG/PNG) · brand (≤70) · price as “amount CURRENCY” · availability (in_stock / out_of_stock / pre_order / backorder / unknown) · seller_name · target_countries.
The control flags
is_eligible_search — appear in ChatGPT answers. is_eligible_checkout — marks a row checkout-ready (requires search=true plus live seller_privacy_policy and seller_tos URLs); ChatGPT does not currently run in-chat checkout for merchants. is_ads_eligible — ads feeds only.
What actually trips stores up
Variants not expanded to their own rows with group_id + variant_dict · HTML left inside descriptions · prices without a currency code · missing GTIN/MPN without identifier_exists=no · sale prices not lower than list price · policy URLs that 404. Malformed rows are rejected; variants without group_id are treated as separate single listings, which weakens how they display.
Freshness
OpenAI asks for a full snapshot at least daily, with API updates in between; availability and price are ranking factors. We regenerate and push on schedule for connected stores.
