FBAInventoryReimbursement breakdowns listTransactions

FBAInventoryReimbursement breakdowns listTransactions focuses on migration mapping and reconciliation evidence, not generic API copy. Use it to turn a vague migration into a reviewable test case.

Official status

Amazon documentation lists FBA reimbursement event buckets as in-scope for this migration. Use the official source before code freeze because deadlines and replacement details can change.

Production Finances validation plan

Finances migration must protect accounting completeness. The validator evidence should be paired with a manifest that proves windows, nextToken pagination, recursive breakdowns and expected totals for representative close periods.

Validation areaProduction proof to collect
Date windowsSplit requests into 180-day-or-smaller UTC windows and record the generated ranges.
PaginationContinue on empty pages when nextToken exists and preserve postedAfter/postedBefore on every token request.
BreakdownsReconcile recursive amounts with deterministic decimals instead of floats.
IdentifiersValidate order, settlement and transaction identifiers against expected ledger joins.

Mapping table

FBAInventoryReimbursement breakdowns listTransactions should be implemented as a small, reviewable mapping table before release.

Old field or behaviorNew field or behaviorValidation rule
transactionTypeFBAInventoryReimbursement-style transactionClassify reimbursement separately from shipment or refund.
totalAmounttransaction totalPreserve even when item breakdowns are null.
transaction breakdownsbreakdowns[]Use transaction-level breakdowns before item-level fallback.

Validation scenario

Use one reimbursement sample where transaction-level totals exist and item-level breakdowns are null.

Input evidenceExpected proof
Source scan findingAMZ-FIN-BREAKDOWN-001, AMZ-FIN-RECON-001 points to the old implementation.
Sample dataThe migration sample covers the field, status, amount or identifier in this page.
Reviewer outputA short reconciliation note explains every accepted delta.

Parser or reconciliation example

Use this as the shape of the unit test or review snippet; adjust names to your codebase.

if (txn.transactionType.includes('Reimbursement')) {
  reconcile(txn.totalAmount, txn.breakdowns ?? [], txn.items ?? []);
}

What breaks

AreaBreakage
Code patternCode still assumes FBA reimbursement event buckets.
Payload or schemaThe migration target is listTransactions reimbursement transactions with totalAmount and breakdowns, so shape, naming or grouping changes.
Permission or data accessField visibility, role access or accounting availability can differ by marketplace and workflow.
Pagination, status or field mappingMapping mistakes can hide under successful HTTP responses unless samples are reconciled.

Before/after example

The example is intentionally small so the migration shape is visible in a code review.

Before:
// Old assumption
FBA reimbursement event buckets

After:
if (txn.transactionType.includes('Reimbursement')) {
  reconcile(txn.totalAmount, txn.breakdowns ?? [], txn.items ?? []);
}

FAQ

What should FBAInventoryReimbursement breakdowns listTransactions prove?

It should prove that FBA reimbursement event buckets maps safely to listTransactions reimbursement transactions with totalAmount and breakdowns for the tested workflow.

What evidence belongs in the ticket?

The source finding, mapping table result, sample input, normalized output and reconciliation note.

Can the page replace production validation?

No. It gives the mapping contract and sample gate; production rollout still needs staged validation.

How does the scanner help?

It flags AMZ-FIN-BREAKDOWN-001, AMZ-FIN-RECON-001 evidence and links findings to the relevant mapping or validator page.
