Metric top items
Lists the items behind one Shop Performance Score metric. itemType says what the rows are: products for NRR and NBFR, logistics_providers for OTDR, and aftersales_types for AHT. A metric TikTok adds later comes back as unknown. Rows use camelCase keys from TikTok’s fields, for example productId, productName, deliveredOrderCount, negativeOrderCount and topReviewReasons for products.
The list isn’t paged. TikTok has no top items for SFCR or IM_DSAT, so those codes are rejected; use Metric problem details for them. US shops only. Read live from TikTok.
Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Path Parameters
SPS metric code, case-insensitive. TikTok's codes today: NRR (negative review rate), NBFR (non-buyer-fault return and refund rate), SFCR (seller-fault cancellation rate), OTDR (on-time delivery rate), AHT (after-sales handling time), IM_DSAT (chat dissatisfaction rate). TikTok says the list may grow, so other code-shaped values pass through.
