Migration assurance
listTransactions migration: migration guide and scanner checklist
listTransactions migration explains what replaces Finances v0 event lists, the removal date, the migration risks to validate, and how API Migration Guard detects the pattern.
- Target keyword: listTransactions migration
- Removed: Finances v0 event lists
- Replacement: listTransactions request, page and breakdown model
- Removal date: August 27, 2027
TL;DR
| Deprecated item | Removal date | Replacement | Migration risk | Scanner detection |
|---|---|---|---|---|
| Finances v0 event lists | August 27, 2027 | listTransactions request, page and breakdown model | listTransactions requires a new reconciliation contract, not just endpoint replacement. | AMZ-FIN-OP-001 |
Official status
Amazon documentation lists Finances v0 event lists 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. |
Removed resource and replacement
| Old resource | Replacement | Deadline | Validation outcome |
|---|---|---|---|
| Finances v0 event lists | listTransactions request, page and breakdown model | August 27, 2027 | listTransactions requires a new reconciliation contract, not just endpoint replacement. |
What breaks
| Area | Breakage |
|---|---|
| Code pattern | Finances v0 event-list call or endpoint usage for Finances v0 event lists. |
| 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:
const events = await listFinancialEvents({ PostedAfter: start });
After:
const pages = await collectListTransactions({ postedAfter: start, postedBefore: end });Scanner detection
| Rule ID | Severity | Evidence pattern | False positive condition | Validation step |
|---|---|---|---|---|
| AMZ-FIN-OP-001 | BLOCKER or HIGH depending on source evidence | Finances v0 event lists | 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 migration?
listTransactions request, page and breakdown model
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.
