    sourceOfFunds: {
        type: "CARD"
    },
    order: {
        walletProvider: "MASTERPASS_ONLINE"

};

Rupay.initiateAuthentication("1234", "XYZ", function (data) {
    if (data && data.error) {
        var error = data.error;
        // Something bad happened, the error value will match what is returned by the Authentication API
        console.error("error.code : ", error.code);

        console.error("error.result : ", error.result);

            case "RESUBMIT_WITH_ALTERNATIVE_PAYMENT_DETAILS":
                tryOtherPayment(); //Card does not support 3DS and transaction filtering rules require 3DS on this transaction: Ask the payer to select a different payment method

}, optionalParams);

Arguments Copied to clipboard

orderId String REQUIRED

Unique identifier for this order.

transactionId String REQUIRED

Unique identifier for this payment authentication.

callback Function REQUIRED

The callback function.

optionalParams Object

Optional parameters contain white labeled api parameters.

correlationId String

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, XSD type String

Min length:1

Max length:100

order Object

Information about the order associated with this transaction.

walletProvider Enumeration

The wallet provider used to collect the customer's payment details used for this transaction.

Value must be a member of the following list. The values are case-sensitive.

AMEX_EXPRESS_CHECKOUTAmex Express Checkout wallet provider.

ANDROID_PAYAndroid Pay mobile wallet provider.

APPLE_PAYApple Pay mobile wallet provider.

CHASE_PAYChase Pay wallet provider.

GOOGLE_PAYGoogle Pay mobile wallet provider.

MASTERPASS_ONLINEMasterPass Online wallet provider.

SAMSUNG_PAYSamsung Pay mobile wallet provider.

VISA_CHECKOUTVisa Checkout wallet provider.

session Object

version String

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, JSON type String

Min length:10

Max length:10

sourceOfFunds Object

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.

provided Object

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.

card Object

Details as shown on the card.

devicePayment Object

If the payer chose to pay using a device you must provide payment details in this parameter group. Use this parameter group when accepting payments using device payment methods such as Apple Pay, Android Pay or Samsung Pay.

paymentToken String

This is the payment token that you received from the device's payment SDK.

For example:

For Apple Pay - this is the PKPaymentToken.paymentData value.

For Google - this is PaymentMethodToken.getToken().

Note 1: The gateway API considers this value to be a string, NOT JSON itself. Therefore, when using the JSON gateway API, this field will typically look like:

"sourceOfFunds": {
"provided": {
"card": {
"devicePayment": {
"paymentToken": "{\"data\":\"869ss19ew ....

Note 2: The gateway will ignore the currency and amount information in the payment token, and will instead use the values passed on the amount and currency fields. For normal usage, you should populate those fields with the exact same values as you got from the SDK.

Data can consist of any characters, JSON type String

Min length:1

Max length:16384

number Digits

The account number of the payer's account used for this authentication.

On requests, provide the number in the form that you receive it (as explained below). On responses, the gateway populates it with a form that the payer would recognize (also explained in more detail below).

Request

On request, populate this field based on the payment method you are using for the payment:
- Card: the account number embossed onto the card.
- Scheme tokens such as MDES (Mastercard Digital Enablement Service) - supply the value called the "Token PAN" or VTS (Visa Token Service) - supply the value called "token".
Response

On return, the card number will be populated in 6.4 masking format, for example, 000000xxxxxx0000.

Data is a string that consists of the characters 0-9, JSON type String

Min length:9

Max length:19

token Alphanumeric

Gateway token that uniquely identifies a card and associated details.

Data may consist of the characters 0-9, a-z, A-Z, JSON type String

Min length:1

Max length:40

type Enumeration

The payment method used for this authentication.

If you are passing card or scheme token data on the API, then you need to set this value, and also provide the card or token details in the sourceOfFunds.provided.card group.

If you are making a payment with a gateway token, then you can leave this field unset, and only populate the sourceOfFund.token field.

Value must be a member of the following list. The values are case-sensitive.

CARDUse this value for authentications using the card number.

SCHEME_TOKENUse this value for authentications using scheme tokens.
