Official status

Amazon documentation lists listFinancialEventsByGroupId 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.

FINANCIAL_EVENT_GROUP_ID filter proof

Group-level migration is risky because settlement or close-period rollups can look plausible while filtering the wrong identifier. Make the manifest prove the group ID filter, page chain and totals together.

CheckExpected evidence
Request filterrelatedIdentifierName=FINANCIAL_EVENT_GROUP_ID with the original group ID as relatedIdentifierValue.
Window contextpostedAfter and postedBefore match the finance close period being validated.
PaginationnextToken pages keep the same group ID arguments and do not switch to token-only requests.
RollupBreakdown totals reconcile to the expected group-level amount before the old call is removed.

What breaks

AreaBreakage
Code patternFinances v0 event-list call or endpoint usage for listFinancialEventsByGroupId.
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:
await finances.listFinancialEventsByGroupId(groupId);

After:
await finances.listTransactions({ postedAfter, postedBefore, relatedIdentifierName: 'FINANCIAL_EVENT_GROUP_ID', relatedIdentifierValue: groupId });

FAQ

What replaces listFinancialEventsByGroupId replacement?

listTransactions with relatedIdentifierName=FINANCIAL_EVENT_GROUP_ID

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.
