This identifier can be up to 12 characters in length.


Data may consist of the characters 0-9, a-z, A-Z, '-', '_'

Min length: 1 Max length: 40

Fields

correlationId String OPTIONAL

A transient identifier for the request, that can be used to match the response to the request.

The value provided is not validated, does not persist in the gateway, and is returned as provided in the response to the request.

Data can consist of any characters

Min length: 1 Max length: 100
order.currency Upper case alphabetic text REQUIRED

The currency of the order expressed as an ISO 4217 alpha code, e.g. USD.

Data must consist of the characters A-Z

Min length: 3 Max length: 3
responseControls OPTIONAL

Container for fields that control the response returned for the request.

responseControls.sensitiveData String OPTIONAL

Indicates how sensitive data is returned in the response.

Data can consist of any characters

Min length: 1 Max length: 50
session.id ASCII Text OPTIONAL

Identifier of the payment session containing values for any of the request fields to be used in this operation.

Values provided in the request will override values contained in the session.

Data consists of ASCII characters

Min length: 31 Max length: 35
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.

See Making Business Decisions Based on Session Content.

Data consists of ASCII characters

Min length: 10 Max length: 10
sourceOfFunds REQUIRED

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.

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). However, for some payment types (such as giropay), you must collect the information from the payer and supply it here.

sourceOfFunds.provided.giftCard OPTIONAL

If the payer chose to pay using a gift card, you must submit sourceOfFunds.type=GIFT_CARD and provide the payer's gift card details in this parameter group.

sourceOfFunds.provided.giftCard.expectedLocalBrand String OPTIONAL

Do not provide this field in your request unless instructed to do so by <<paymentServiceProvider>>.

The field is required, if your gift card numbers do not use ISO BIN rules and therefore not allowing the gateway to identify the local brand.
