sourceOfFunds   = COMPULSORY

Information about the payment type selected by the payer for this payment and the source of the funds.
Depending on the payment type the source of the funds can be a debit or credit card, bank account, or account with a browser payment provider (such as PayPal).

For card payments the source of funds information 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.

session.version  ASCII Text = OPTIONAL

Use this field to implement optimistic locking of the session content.
Do this if you make business decisions based on data from the session and wish to ensure that the same data is being used for the request operation.

To use optimistic locking, record session.version when you make your decisions, and then pass that value in session.version when you submit your request operation to the gateway.

If session.version provided by you does not match that stored against the session, the gateway will reject the operation with error.cause=INVALID_REQUEST.

Fixed value

sourceOfFunds.provided   = OPTIONAL

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).
