Min length: 1 Max length: 100
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 REQUIRED

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.card REQUIRED

Details about the card.

Use this parameter group when you have sourced payment details using:
Cards: the card details entered directly or collected using a Point of Sale (POS) terminal.
Device payment methods such as Apple Pay, Android Pay, Samsung Pay or Google Pay.
Digital wallets such as Masterpass, Visa Checkout or Amex Express Checkout.
Card scheme tokens where the card was tokenized using a card scheme tokenization service such as Mastercard Digital Enablement Service (MDES).
Alternative IDs provided by the schemes, such as Alt-Id for Guest Checkout payments in India using American Express, Rupay cards issued in India.

sourceOfFunds.provided.card.emvRequest String REQUIRED

This field only applies to transactions that originate from an EMV capable terminal.

It contains selected EMV fields as provided by the terminal.

For the list of field tags to include (if provided by the terminal), see Card Present Payments. Requests with any other tags are rejected by the gateway.

Some of the tags represent data that can occur on explicit fields in this API. You can submit the value either in this field, or in both places. For example, the PAN can be presented as EMV tag 5A in this field, or included both the sourceOfFunds.provided.card.number API field and in EMV tag 5A in this field.

If you specify the EMV tag only, we can populate the explicit field in the API. Fields where this is supported have the text "This field corresponds to EMV tag <tag name>" in their field descriptions.

If you specify both places, there will be no population of the explicit field or validation that the data matches.

The API response will not contain PCI sensitive fields.

The BIN of the card.

If you provide this, the gateway will check that the decrypted PAN has these leading six digits. If the check fails, the gateway will reject the transaction.

If you do not provided this, the gateway will not perform this check.

Data is a string that consists of the characters 0-9.

Min length: 1 Max length: 6
sourceOfFunds.provided.card.p2pe.encryptionState String REQUIRED

sourceOfFunds.type Enumeration REQUIRED

The payment method used for this payment.

If you are passing card data (in any form) on the API, then you need to set this value, and also provide the card details in the sourceOfFunds.provided.card group. In the case of digital wallets or device payment methods, you must also populate the order.walletProvider field.

If you are making a payment with a gateway token, then you can leave this field unset, and only populate the sourceOfFunds.token field. However you can set this to CARD if you want to overwrite or augment the token data with a card security code, expiry date, or cardholder name.
