Overview

Transfers track the lifecycle of money movement. Pay-ins and payouts return or reference transfer IDs, and your platform can use those IDs to check status after the initial request.

Transfer States

Use the API reference for currently documented transfer operations. These docs focus on transfer retrieval and lifecycle tracking.

Endpoint Sequence

POST /v1/payin
POST /v1/payout
GET /v1/transfers/{id}

Pay-ins and payouts create or reference transfers. Public docs should not document hidden transfer creation endpoints.

Transfer Status

Use transfer retrieval when you need to reconcile a pay-in or payout after execution. GET /v1/transfers/{id} accepts either the transfer ID (tr_xxx) or the consumed quote ID (quo_xxx). Store the transfer ID returned by pay-in and payout execution because webhook payloads identify the movement with that ID.

For crypto pay-in deposits, the transfer from.rail value is the blockchain network that delivered the funds, such as polygon, solana, or tron.
