Turn Merchant API migration risk into a repeatable agency service.

Use checklist mode for sales calls and source-limited clients, Code mode for targeted snippets, and ZIP mode only for approved focused folders.

Group blockers by merchant admin, vendor, agency developer, ads specialist, and platform app.

Deliver rule IDs, severity, confidence, evidence, remediation, validation steps, source deletion proof, and NOT_VERIFIED gaps.

Keep paid claims out of proposals until payment, legal, and production evidence pass.

Use follow-up scans to prove regression risk is reduced after client fixes.
