How to Use the Merchant Center Feed Attribute Repair Prompt to Clear GTIN and Shipping Rejections
Turn Merchant Center product feed rejections into a repair plan: fix GTIN, MPN, and brand identity rules, image policy failures, shipping and return attributes, then produce a supplemental feed patch sheet merchandisers can upload without guessing column names.
Merchant Center rejections often look like a mysterious red badge when the real problem is a bad GTIN, a tiny image, or shipping attributes that never made the feed. The Google Merchant Center Product Feed Attribute Repair Planner: GTIN MPN Brand Rules, Image Requirements, Shipping Attributes, and a Supplemental Feed Patch Sheet prompt is an attribute repair planner: triage issue codes, apply GTIN MPN brand rules for your vertical, fix image and shipping fields, and emit a supplemental feed patch sheet your merchandiser can upload.
What the prompt produces
- An issue triage table mapping each rejected offer to a root cause and fix.
- A GTIN MPN brand rule card for apparel, media, or hard goods.
- An image fix list tied to failing offers with confirm flags for current specs.
- Shipping attribute guidance for your markets and return URL.
- A supplemental feed patch sheet with Google column headers and corrected rows.
- A revalidation checklist so you do not request review too early.
- Prevention notes for Shopify or your feed source so the next sync stays clean.
- A FAQ that bans fake GTINs and magical white background myths.
How to fill the inputs
FeedSource should say how the primary feed is built. App sync versus Content API versus CSV changes the prevention advice.
RejectedOffers needs real item ids, titles, brand, GTIN, MPN, image links, and the issue codes from Merchant Center.
ShippingAndReturns should describe table rates or carrier calculated shipping and a returns URL if you have one.
ProductVertical changes identifier rules. Hard goods and apparel are not identical.
TargetMarkets keeps shipping(country:...) attributes honest.
Reading the example output
The sample repairs a brass lamp missing GTIN with a small image and a serum with an invalid GTIN plus missing shipping.
- Fake GTINs are refused; brand plus MPN is the fallback when no GTIN exists.
- Supplemental columns override the primary feed for the two ids.
- Prevention maps Shopify barcode and vendor fields so the app feed stops reintroducing blanks.
Tips for better results
- Patch supplemental first to clear the fire, then fix the primary source of truth.
- Verify check digits with packaging before reupload.
- Align account level shipping services so every offer does not need a one off shipping attribute.
Mistakes to avoid
- Do not invent GTINs to clear missing_gtin.
- Do not delete shoppable offers just to empty the issue list.
- Do not confuse this attribute repair planner with a generic account disapproval triage if your problem is domain verification or misrepresentation suspensions.

Supplemental versus primary feed
Use the supplemental patch to stop the bleeding on a handful of SKUs, then fix the primary feed so tomorrow's sync does not reopen the same issues. Merchandisers who only patch supplemental forever end up with two sources of truth and a spreadsheet nobody trusts.
When identifier_exists is the right tool, document why the product has no GTIN in your PIM notes. Marketplaces and ads surfaces still expect honesty about identifiers. A cleared issue that returns after the next Shopify sync usually means barcode or vendor fields were never updated in admin.
Image and shipping gotchas
Image overlays with prices or "sale" banners are a frequent silent fail. Export a clean hero image before you blame the feed connector. Shipping gaps often mean account level services were never configured for the target country, so every offer looks incomplete even when the product row is fine.
After upload, wait until Merchant Center shows the attribute update before you click request review. Reviewing a feed that still displays the old GTIN wastes a cycle.
