The details describing the source of the funds to be used.
For card payments these may be represented by combining one or more of the following: explicitly provided card details, a session identifier which the gateway will use to look up the card details and/or a card token. Precedence rules will be applied in that explicitly provided card details will override session card details which will override card token details. Each of these may represent partial card details, however the combination must result in a full and complete set of card details. See Using Multiple Sources of Card Details for examples.
Information about the source of funds when it is directly provided (as opposed to via a token or session).
For browser payments, the source of funds details are usually collected from the payer on the payment provider's website and provided to you when you retrieve the transaction details (for a successful transaction). However, for some payment types (such as giropay), you must collect the information from the payer and supply it here.
For ACH payments (sourceOfFunds.type=ACH) you must provide values for all fields within this parameter group, including details about the payers bank account as well as the type of ACH payment.
It is your responsibility to authenticate the payer and obtain authorization from the payer in accordance with the NACHA Operating Rules and Guidelines for the Standard Entry Class (SEC) associated with this payment. For details please refer to https://www.nacha.org/.
