Product feeds
Path: Admin > Products > Feeds (/admin/products/feeds)
A product feed is a file with your catalog that price comparison sites and shopping platforms fetch regularly (Google Shopping, Heureka, Zboží.cz, and now also ChatGPT Shopping). A feed puts your products where customers are searching.
Creating a feed
- Open Admin > Products > Feeds and click + Create feed.
- Pick a platform (e.g. Heureka, Google Merchant, OpenAI / ChatGPT Shopping).
- Choose a format and an update frequency.
- Fill in the platform-specific settings (below) and save.
A feed has its own public URL. You can optionally protect it with a username and password (HTTP Basic) — note that a protected feed is never linked in llms.txt (see AI Visibility).
Products without a price or image
A product (or variant) without a regular price or without an image is not included in the feed and is skipped. Make sure your prices and images are filled in.
OpenAI / ChatGPT Shopping
The new "OpenAI / ChatGPT Shopping" platform builds a feed to the OpenAI merchant spec (see chatgpt.com/merchants) so your products can appear in ChatGPT Shopping. Supported formats: CSV, JSON and XML.
Platform settings:
| Setting | Default | Meaning |
|---|---|---|
| Brand Name | — | Fallback brand for products that have none of their own. |
| Enable search | On | Products may appear in ChatGPT Shopping results. |
| Enable checkout | Off | In-chat purchasing — requires OpenAI checkout onboarding. Leave off until you are approved. |
| Variant Handling | Grouped | Group variants (include item_group_id) or export each variant as a standalone product (no item_group_id). |
| Return / Privacy / Terms URLs | — | Links to your policies; recommended for approval. |
If a product has no brand of its own, the "Brand Name" from settings is used; if that is empty, the feed's default brand is used. If a product has variants, only the variants go into the feed (not the parent product).
Other platforms
Merzio also supports feeds for Heureka (SK/CZ), Zboží.cz and Google Merchant. The Google Merchant feed is also the foundation for AI assistant recommendations — see the AI shopping checklist in AI Visibility.
