listTransactions 180-day window: migration guide and scanner checklist
listTransactions 180-day window explains what replaces Finances date ranges over 180 days, the removal date, the migration risks to validate, and how API Migration Guard detects the pattern.
- Target keyword: listTransactions 180-day window
- Removed: Finances date ranges over 180 days
- Replacement: Chunked listTransactions windows of 180 days or fewer
- Removal date: August 27, 2027
TL;DR
| Deprecated item | Removal date | Replacement | Migration risk | Scanner detection |
|---|---|---|---|---|
| Finances date ranges over 180 days | August 27, 2027 | Chunked listTransactions windows of 180 days or fewer | A too-large range can return empty results and hide missing financial data. | AMZ-FIN-WINDOW-001 |
Official status
Amazon documentation lists Finances date ranges over 180 days 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 area | Production proof to collect |
|---|---|
| Date windows | Split requests into 180-day-or-smaller UTC windows and record the generated ranges. |
| Pagination | Continue on empty pages when nextToken exists and preserve postedAfter/postedBefore on every token request. |
| Breakdowns | Reconcile recursive amounts with deterministic decimals instead of floats. |
| Identifiers | Validate order, settlement and transaction identifiers against expected ledger joins. |
UTC window split with replay overlap
The safest 180-day migration is deterministic: split in UTC, keep the end boundary exclusive, and replay a small overlap during validation so boundary transactions can be deduplicated by transactionId instead of silently dropped.
| Step | Rule |
|---|---|
| Normalize | Convert postedAfter and postedBefore to UTC instants before splitting. |
| Split | Emit windows of 180 days or fewer, using [start, end) semantics. |
| Overlap validation | Replay a 5-minute overlap in the test manifest and deduplicate by transactionId. |
| Recent-data guard | Keep postedBefore more than two minutes before request time for production jobs. |

let cursor = startUtc;
while (cursor < endUtc) {
const next = min(addDays(cursor, 180), endUtc);
yield { postedAfter: cursor.toISOString(), postedBefore: next.toISOString() };
cursor = next;
}
}

| Old resource | Replacement | Deadline | Validation outcome |
|---|---|---|---|
| Finances date ranges over 180 days | Chunked listTransactions windows of 180 days or fewer | August 27, 2027 | A too-large range can return empty results and hide missing financial data. |
What breaks
| Area | Breakage |
|---|---|
| Code pattern | Finances v0 event-list call or endpoint usage for Finances date ranges over 180 days. |
| Payload or schema | listTransactions uses transaction objects, recursive breakdowns and Currency object amounts. |
| Permission or data access | Recent data and date-window behavior need operational validation before financial close. |
| Pagination, status or field mapping | Windows 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 listTransactions({ postedAfter: '2026-01-01T00:00:00Z', postedBefore: '2026-12-31T00:00:00Z' });
After:
for (const window of splitInto180DayWindows(start, end)) await listTransactions(window);Scanner detection
| Rule ID | Severity | Evidence pattern | False positive condition | Validation step |
|---|---|---|---|---|
| AMZ-FIN-WINDOW-001 | BLOCKER or HIGH depending on source evidence | Finances date ranges over 180 days | Documentation, comments, generated clients or test fixtures can require manual review. | Replace the v0 financial-event call with listTransactions and preserve request arguments on token pages. |
Migration checklist
- Replace the v0 financial-event call with listTransactions and preserve request arguments on token pages.
- Split postedAfter..postedBefore ranges into 180-day-or-smaller UTC windows.
- Validate a request manifest and page samples in the Finances Reconciliation Validator.
- Compare recursive breakdown totals and duplicate transaction IDs before using the output for accounting.
Common mistakes
- Stopping on an empty transactions array while nextToken still exists.
- Sending a token-only follow-up request without original listTransactions arguments.
- Flattening recursive breakdown totals with floats instead of deterministic decimals.

FAQ
What replaces listTransactions 180-day window?
Chunked listTransactions windows of 180 days or fewer
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.
