Get Unmatched FNSKUs for Cost Entry
GET/api/amazon/cost-entries/:costEntry/unmatched-fnskus
For a cost entry automatically created from an Amazon storage fee report (monthly storage fees or the long-term/aged inventory surcharge), returns the per-FNSKU fee rows that could not be allocated to a product because the FNSKU has no product mapping.
Any valid API token can call this endpoint — no specific scope required. Manage tokens.
The unmatched breakdown is not persisted on the cost entry; it is recomputed on demand by re-aggregating the source report's per-FNSKU fees for the entry's source month with the same logic that built the original allocations. FNSKUs whose fee rounds to zero, or that have since been mapped to a product, are excluded.
Each row contains: fnsku, product_name (as reported by Amazon, may be null), and fee (in major currency units). Returns 404 when the cost entry was not created from an Amazon report, when it is not a storage fee entry type, or when the source report no longer exists. This endpoint is not scoped to an integration instance.

Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.
Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.

Rate limited — platform limit is 1,000 requests/min; individual tokens may carry lower limits. Honor the Retry-After header before retrying. See the Rate Limits guide.
