​
What this audit checks

​
Authentication & access

  • Partner refresh token present and exchangeable at /oauth/token (no expired-grant errors)
  • Granted scopes cover seller_read, listing_read, order_read
  • /v1/seller/account returns a resolvable seller_id matching the configured credential

​
Account health & policy compliance

  • Seller account status is ACTIVE (not RESTRICTED or SUSPENDED) on /v1/seller/account
  • Seller rating at or above 4.7 and response_rate within healthy band
  • No open policy strikes or prohibited-item flags against the account

​
Listing quality & suppression

  • Suspended listings count is zero on /v1/listings (status=SUSPENDED)
  • Brand attribute filled on at least 80% of active listings (search filter coverage)
  • Condition grade set on every listing (NEW / LIKE_NEW / GOOD / FAIR / POOR)
  • Listings within the 7-day freshness boost window above the re-list threshold
  • Featured-offer (search-rank boost) win rate at or above target across active listings
  • Smart Pricing floor not breached - no listings holding at smart_pricing_floor
  • Average listing age under 14 days so freshness boost is not eroded

​
Order defect & feedback

  • Return rate under 8% over trailing 30 days on /v1/orders
  • No grading-drift signal - returns on GOOD / LIKE_NEW items with condition-mismatch reason
  • Ships-within-3-days rate at or above 90% to hold the Fast Shipper badge
  • No orders past ship_deadline currently in PAID state

​
Cross-channel inventory & pricing parity

  • No ON_SALE Mercari listing for an item sold or zero-stock on a BigCommerce / Depop / Vinted sibling
  • Same item priced within 15% across Mercari and Depop / Vinted siblings (title_hash match)
  • Mercari order synced to BigCommerce / Shopify order within 24h (order_ref match)
