Audit engagement
API Transaction Audit Review
A structured review of how payment, ledger, and partner API calls move money and records across your stack — with findings tied to control gaps, not feature wish lists.
Who this is for
Fintech compliance leads, treasury operations managers, and engineering managers who need an independent reading of transaction trails before a regulator visit, partner diligence, or a major release.
Outcome
A written audit pack covering sampled transaction paths, control weaknesses, evidence gaps, and a prioritized remediation sequence your team can act on within a fixed engagement window.
Included
- Scoped inventory of in-scope API endpoints that create, reverse, or settle transactions
- Sampling of live and historical request/response trails against your stated controls
- Reconciliation checks between API outcomes and ledger or settlement records you provide
- Written findings report with severity ranking and remediation owners
- Closing walkthrough with your compliance and engineering contacts in Taiwan time zone
Not included
- Ongoing monitoring subscriptions or hosted dashboards
- Source-code rewrite or production incident response retainers
- Legal opinions or formal regulatory filings
- Penetration testing outside the agreed transaction paths
How we work
-
Brief and boundary
We confirm systems in scope, time window, sample size, and the controls you claim to enforce on API-originated transactions.
-
Trail collection
Your team shares logs, settlement files, and access for read-only review; we map each sampled path from call to ledger effect.
-
Finding and challenge
We document mismatches, missing approvals, silent retries, and weak segregation — then challenge them with your operators before final wording.
-
Delivery
You receive the audit pack and a scheduled walkthrough so owners leave with clear next steps.
