refundId uniquely identifies the refund itself, while paymentId identifies the payment being
refunded. A payment can have several partial refunds, so use refundId to tell them apart and to
process refund webhooks idempotently. It matches the id returned by the
View Refund Information for Payment
endpoint. The same field is present on the Refund Complete, Refund Failure, and
Refund Returned events.
Advanced: Disbursement Events
Coinflow decouples disbursement (sending the funds to the merchant on-chain) from settlement. The Disbursed Funds event fires as soon as a USDC or Credits disbursement transaction succeeds and a transaction signature is available β which may be before or independent of the Settled event.
Use Disbursed Funds when you need the on-chain transaction signature for every disbursement. Unlike Settled, this event always includes the signature.
1 // Sent when funds are successfully disbursed on-chain (USDC or Credits) and the transaction signature is available 2 { 3 "eventType": "Disbursed Funds", 4 "category": "Purchase", 5 "created": "2025-04-28T20:11:07.608Z", 6 "data": { 7 "id": "0197a7e7-54e4-74c9-b708-1632923c1bf0", 8 "merchantId": "testtest", 9 "signature": "3zP3VcWM6rKF1izpnWn5rJ7XJucoEicwncQ9hvGR7Q7FuGvDPenfBrfLUVc4fjbYghnzauTDfY4c8Jc2Nb5y1AWm", 10 "settlementType": "USDC", 11 "blockchain": "solana", 12 "amount": { 13 "cents": 546, 14 "currency": "USD" 15 }, 16 "disbursedAt": "2025-04-28T20:11:07.608Z" 17 } 18 }

Unknown Wire Payment Events
An Unknown Wire Payment Received event fires exactly once when an incoming wire cannot be matched to a pending payment (token, memo, and fuzzy match all fail) and is recorded as an unknown wire on your account. The payload includes enough detail for you to look up the wire in your own systems and initiate reconciliation or a return.
