At a glance
Listings Failing Feedonomics Feed Validation is the share of items pushed through Feedonomics that Walmart rejects at ingestion. Rejected listings never reach the catalogue, so they stay hidden and earn nothing until the feed is cleaned. A rising rejection rate is an early sign that a feed mapping or attribute rule has broken, which is why this is a hero card.
Calculation
The value is derived by comparing the number of Feedonomics-distributed listings rejected at Walmart ingestion against the total submitted through the feed in the window, then expressing the result as a percentage. It is a cross-platform measure that depends on the feed pipeline being linked. See the At a glance summary for the window and unit, and the worked example below for how the figure reads in practice.Worked example
A representative reading of Listings Failing Feedonomics Feed Validation for a typical merchant on Walmart Marketplace. On 12 Mar 26 a seller pushing about 800 items through Feedonomics in the trailing 7 days sees the rejection rate climb to 7.5%, around 60 items, over the alert line. The rejections cluster on a single category where a required attribute mapping was dropped in the latest feed template. The action is to fix the mapping in Feedonomics, resubmit the affected batch, and confirm the rate falls back so the hidden items return to the catalogue.
