listFinancialEvents replacement: migration guide and scanner checklist

listFinancialEvents replacement explains what replaces listFinancialEvents, the removal date, the migration risks to validate, and how API Migration Guard detects the pattern.

Official status

Amazon documentation lists listFinancialEvents 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.

FinancialEvents to Transactions reconciliation map

The replacement is a model migration. Teams that only rename listFinancialEvents to listTransactions often lose the relationship between transaction identity, related identifiers, recursive breakdowns and ledger totals.

v0 habitlistTransactions proofReview question
Read event buckets by event typeGroup transactions by transactionType and transactionStatus.Does the new grouping match the old close report?
Sum top-level event amountsSum totalAmount and recursive breakdown amounts separately.Can reviewers explain any delta?
Join on order ID inside event payloadsUse relatedIdentifiers and transactionId explicitly.Are duplicate or missing joins visible in the manifest?
Assume recent orders are completeKeep a close-window delay policy in the runbook.Does finance know which recent period is still settling?

What breaks

AreaBreakage
Code patternFinances v0 event-list call or endpoint usage for listFinancialEvents.
Payload or schemalistTransactions uses transaction objects, recursive breakdowns and Currency object amounts.
Permission or data accessRecent data and date-window behavior need operational validation before financial close.
Pagination, status or field mappingWindows over 180 days can return empty results; nextToken pages must preserve the original arguments.

Before/after example

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

Before:
const events = await finances.listFinancialEvents({ PostedAfter: start });

After:
const txns = await finances.listTransactions({ postedAfter: start, postedBefore: end });

FAQ

What replaces listFinancialEvents replacement?

listTransactions in Finances API v2024-06-19

Why does the 180-day window matter?

Amazon can return an empty response when the postedAfter..postedBefore range is more than 180 days.

Can a sample prove every finance total?

No. It proves the supplied pages and manifest reconcile within tested scope; production close still needs staged validation.
