Get FBA Inventory Adjustment Breakdown
GET/api/amazon/unified/fba-reimbursement-reconciliation/adjustment-breakdown
Explains where each month's FBA inventory adjustment went: every lost unit's FIFO cost is placed in exactly one bucket, and whatever the loss events cannot explain is left as undetermined. Costs are your own inventory cost, so they are in your base currency (currency). target_share is the undetermined share to aim below (0.02 = 2%).
This endpoint currently requires session authentication; Personal Access Token scope support is in progress.
Query parameters (all optional):
integration_instance_ids— comma-separated Amazon integration IDs.months— how many months back to cover, including the current one (1–24, default 12).
Each month has month (YYYY-MM), total_units, total_cost, undetermined_share and buckets, each with key, label, units, cost and share of the month's cost. Bucket keys: reimbursed (paid for; cost moved to cost of goods sold), found (found again or reversed), replaced (Amazon sent a replacement unit), settling (still inside the research window), damaged (never returns and not claimable), disposed, unpaid_claimable (unpaid, claim window open), unpaid_expired (unpaid, claim window closed — a write-off), undetermined.
