Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it. **Card class:** [Hero](/nerve-centre/overview#card-classes-explained) • **Category:** [Marketplace](/nerve-centre/connectors#connectors-by-type) ## 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. | | | | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ | | **What it counts** | The percentage of Feedonomics-distributed listings rejected at Walmart Marketplace ingestion in the window. | | **Sample type** | Backend API data from Walmart Marketplace, refreshed on the standard data refresh. | | **Why it matters** | Rejected items stay hidden until corrected, so a higher rate means sellable inventory is sitting offline and revenue is being left on the table. | | **Reading the value** | Lower is better; a rising percentage points to a feed mapping or data quality problem. | | **Currency** | percent | | **Time window** | `7D` | | **Alert trigger** | `>5% feed rejection rate` | | **Sentiment key** | `wal_xc_feed_rejection_vs_listings` | | **Roles** | owner, operations, engineering | ## 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-channel 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.

For divergence investigations, use Vortex Mind. ## Known limitations / merchant FAQs **Q: How often does Listings Failing Feedonomics Feed Validation update?** The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard. **Q: Why does my Walmart Seller Center show a different number?** Seller Center reports ingestion results per feed submission and over its own window, while Vortex IQ measures rejections as a rate across the rolling 7-day window. Aligning the period and counting the same submissions usually reconciles the two. **Q: Does a successful resubmission clear an item from this rate?** Once a corrected item passes validation on resubmission, it no longer counts as rejected at the next refresh. Persistent failures mean the underlying mapping or attribute issue is still present. **Q: Can I customise the alert threshold?** Yes, sensitivity thresholds are configurable per profile in the Sensitivity tab. Adjust to match your business baseline rather than relying on the generic default. *** ### Tracked live in Vortex IQ Nerve Centre *Listings Failing Feedonomics Feed Validation* is one of hundreds of KPI pulses Vortex IQ tracks across Walmart Marketplace and 70+ other ecommerce connectors.
