CHATGPT SHOPPING · PRODUCT FEED & AGENTIC COMMERCE
WHAT WE HANDLE
In ChatGPT a product search does not end on a category page but on a handful of specific items. Which ones is decided not by your shop design but by the quality of your product data. That is exactly where we work.
WHERE THE LINES SIT
They get confused often. The difference decides what you actually need to prepare.
A labelled ad next to the answer, billed on CPM or CPC. Works from day one, ends with the budget. See the page →
Your content gets named as a source inside the answer. No click price, but weeks to months of lead time. See the page →
Your individual items appear in the product results because OpenAI knows your catalogue. Not an ad, not copy — a data problem.
HOW IT WORKS TECHNICALLY
The specification is manageable. Keeping it clean over time is the hard part.
| Topic | Requirement |
|---|---|
| Required fields | item_id, title, description, url, brand, seller_name, image_url, availability, price |
| Price format | Amount and currency, for example 79.99 EUR |
| Availability | in_stock, out_of_stock, pre_order, backorder, unknown |
| GTIN | Exactly 8, 12, 13 or 14 digits — with a valid check digit |
| Formats | parquet preferred (ideally with zstd); also jsonl.gz, csv.gz, tsv.gz — always UTF-8 |
| Delivery | Two routes, recommended in combination: SFTP for the full snapshot once a day, API for changes during the day. Small catalogues can run entirely through the API. Promotions are only ever sent via the API. |
| Shards | Up to 500,000 items per shard, files under roughly 500 MB. Products are matched by item_id, not by filename. |
| Retention | A product missing from a snapshot does not vanish at once: the last processed record is retained for up to 14 days. |
| API endpoints | POST /product_feeds creates the feed, PATCH /product_feeds/{id}/products upserts items. Bearer-token auth, with Idempotency-Key and API-Version headers. |
| Prohibited goods | Among others alcohol, nicotine, gambling, weapons, prescription-only medication and unlicensed financial products. We check this before the effort, not after. |
| Access | Currently by application; per OpenAI documentation, initially limited to approved partners |
Based on OpenAI’s public commerce documentation, as of September 2026. The standard behind buying inside the chat is the Agentic Commerce Protocol — it governs checkout, payment and callbacks between shop, AI and payment provider.
