Validation Service Request

When you make the validation request, you must:

Extract the PARes message from the form received from the card-issuing bank.

Remove any spaces created by tabs, spaces, or line breaks from the

PaRes

field. Do not modify any other part of the

PaRes

field.

Send the

PaRes

value to Cybersource in the signed

PaRes

field of the validation service. The response contains the validation result.

You can use the validation and card authorization services in the same request or in separate requests:

Same request—Cybersource automatically attempts to authorize your customer’s card if validation succeeds. The values of the required fields are added automatically to the authorization service. Do not pass any fields that Cybersource derives from the

PaRes

value into the request because that data could be overwritten.

Separate requests—You must manually include the validation result values (Payer Authentication response fields) in the authorization service request (Card Authorization request fields), which are listed in this table:

Identifier	Payer Authentication Response Field	Card Authorization Request Field
XID	payerAuthValidateReply_xid	ccAuthService_xid
E-commerce indicator	payerAuthValidateReply_commerceIndicator	ccAuthService_commerceIndicator
CAVV	PayerAuthValidateReply_cavv	ccAuthService_cavv

If you are currently passing additional card-specific values in the Payer Authentication Validate response for Visa and Mastercard, you can continue to pass them for RuPay.
