CounterpartyPayoutSent
Fired when the payout has been sent to the bank. The funds have left, but the payment is not yet reconciled — a payout can sit in this state for a few days depending on the rail, and can still be returned afterwards. Wait for CounterpartyPayoutCompleted before treating the money as delivered.
The included payload mirrors the payout resource — payoutId, counterpartyId, amount (in cents), currency, status, description, and effectiveDate — so you can act on the event without re-reading the payouts API.

Changes
Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
