FAQ

What records does halfin keep for me?

halfin keeps a durable, attributable record of everything that moves value through your account: invoices and the deposits that settle them, payouts and their approvals, balance conversions, refunds, and an operator audit trail of who did what. Together these are your source records for accounting and reconciliation — the same objects you see in the dashboard, read over the API, and receive as signed webhooks. They are one source of truth, not three views that can disagree, which is what lets your books, your integration, and the platform line up.
