ADDED Item Alerts API Campaign Recommendations API Enhancements

Until now, there hasn’t been a programmatic way to detect item-level issues affecting your advertisers’ campaigns. Campaigns could continue serving against items that were out of stock, disabled, or declining in listing quality — with no signal to act on.

The itemAlerts recommendation type under the Campaign Recommendations API now exposes item-level issues, giving you the information you need to take action on behalf of your advertisers.

Use Item Alerts to:

  • Alert advertisers to item issues before they impact performance
  • Automate remediation workflows based on issue type and priority
  • Surface actionable recommendations directly within your platform

Previously available only for Target ROAS campaigns, itemAlerts is now supported across all campaign types for third-party advertisers.

New and updated alert types in this release:

  1. Item Disablement DISABLEMENT
  2. Price Increase PRICE_INCREASE
  3. Buy Box Win Rate Drop BUYBOX_WIN_RATE_DROP
  4. Listing Quality Score Drop OLQ_SCOREDROP
  5. Low Listing Quality Score OLQ_SCORELOW

Listing quality score now provides granular diagnostics across five dimensions:

  • Content quality
  • Shipping performance
  • Price competitiveness
  • Published and in-stock status
  • Ratings & reviews

Item alerts are refreshed daily. Item alerts are only applicable to Marketplace advertisers.

UPDATED Item Health Snapshot V2 Enhancements

The Item Health Snapshot V2 report now includes additional listing quality metrics, giving you deeper visibility into the factors driving item health and their downstream impact on campaign performance.

New Metrics Available

The following listing quality score metrics are now returned in the report:

  1. Rating and Review Score ratingAndReviewScore
  2. Shipping Score shippingScore
  3. Published And InStock Score publishedAndInStockScore
  4. Price Competitiveness Score priceCompetitivenessScore

Use these signals to identify declining item health earlier and help your advertisers take corrective action before performance is impacted.

Action required — Metric Deprecations

ratingScore and offerScore now return a placeholder value of 0.0 and will be deprecated in a future release. We recommend migrating away from these metrics now to avoid disruption when deprecation is finalized. Use the new listing quality score metrics above as replacements.
