How to retrieve GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2

Official status

Amazon documentation lists Flat File V2 settlement report retrieval as in-scope for this migration. Use the official source before code freeze because deadlines and replacement details can change.

Production Settlement validation plan

Settlement migration is a finance parser rebuild. The production gate is not simply requesting the new report type; it is proving that amount rows, currencies, descriptions and totals reconcile under realistic sample files.

Quick answer

How to retrieve GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 usually means the team knows the report type but not the safe sequence for report discovery, document retrieval and parser validation. The fastest check is: Trace how reportId is obtained before the parser sees a TSV file.

Why this happens

This troubleshooting page is tied to Flat File V2 settlement report retrieval, not a generic SP-API failure.

How to detect it in your code

Search the source, scheduled jobs, generated clients, report configuration and sample fixtures before assuming the issue is only live data.

const report = await findSettlementReport({ reportType: 'GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2', settlementId });
const doc = await getReportDocument(report.reportId);
const rows = parseFlatFileV2(doc);

Fix checklist

• Document the source of reportId for current and historical settlements.
• Keep getReport and getReportDocument calls separate in code review.
• Validate decompression and character encoding before parsing rows.
• Parse by header name and keep amount-type, amount-description, amount and currency together.
• Reconcile one closed settlement against finance expectations.
• Re-scan for createReport misuse and legacy report constants.

Migration risk

A retrieval pipeline can appear migrated while the reportId discovery or document-download step is still manual and fragile.

How API Migration Guard checks it

API Migration Guard scans for exact operation names, report type constants, endpoint strings, query parameters, parser assumptions and token/window loops. Paid reports add file-level findings, remediation notes, sample validation steps, CSV/JSON/SARIF exports and an evidence package.

What breaks

Before/after example

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

Before:
const report = await findSettlementReport({ reportType: 'GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2', settlementId });
const doc = await getReportDocument(report.reportId);
const rows = parseFlatFileV2(doc);

After:
// Fix path: Find the available reportId, download the report document and parse by header name
// Validate with API Migration Guard, sample evidence and a re-scan.

Migration checklist

• Document the source of reportId for current and historical settlements.
• Keep getReport and getReportDocument calls separate in code review.
• Validate decompression and character encoding before parsing rows.
• Parse by header name and keep amount-type, amount-description, amount and currency together.
• Reconcile one closed settlement against finance expectations.
• Re-scan for createReport misuse and legacy report constants.

Common mistakes

• Treating How to retrieve GET_V2_SETTLEMENT_REPORT_DATA_FLAT_FILE_V2 as a transient Amazon outage before checking the request shape.
• Changing code without preserving a sample request, response and report evidence.
• Closing the ticket without re-scanning source and validating the affected sample.
