Source

The source key can return additional information if available. Specifically, if the transfer is an onramp and the funds have already arrived, we will return information about the fiat deposit.

  "source": {
    "payment_rail": "wire",
    "currency": "usd",
    "external_account_id": null,
    "bank_beneficiary_name": "name of person sending money",
    "bank_routing_number": "routing number of the sending bank",
    "bank_name": "name of the sending bank",
    "imad": "imad of incoming wire",
    "omad": "omad of incoming wire (deprecated)"
  }
  ...
}

Destination

The destination field will also return additional information when available. Specifically, if the transfer is an offramp and the payment has been fully processed, we will return information about the outgoing fiat transaction.

    "currency": "usd",
    "external_account_id": "310f23a7-9d15-4a67-b96f-bfe2acf26b00",
