FAQ

How does an instant payout avoid double-paying on a retry?

Each payout carries a caller-supplied idempotency key derived from your ledger — for example the affiliate's account id joined with the earnings period or a unique earnings-event id. If a request times out ambiguously and your client retries, the same key returns the original payout instead of creating a second one. The single-payout case uses exactly the same mechanism a batch run does.
