Calling Cardinal session continue (iOS SDK)

When you have verified that a customer’s card is enrolled in a card authentication program, take the payload, and the

payerAuthEnrollReply_authenticationTransactionID

response field and include them in the Cardinal session continue
function before proceeding with the authentication session

as shown in Example 22

In Continue, you should pass a class conforming to a protocol CardinalValidationDelegate
(and implement a method stepUpDidValidate
) as a parameter. These examples show a class conforming to CardinalValidationDelegate
protocol.

Objective-C Examples

Cardinal session continue (iOS SDK - Objective-C)

@interface YourViewController()<CardinalValidationDelegate>{ //Conform your ViewController or any other class to CardinalValidationDelegate protocol
   
}
@end
  
@implementation YourViewController
  
    /**
     * This method is triggered when the transaction has 
     * been terminated.This is how SDK hands back
     * control to the merchant's application. This method will
     * include data on how the transaction attempt ended and
     * you should have your logic for reviewing the results of
     * the transaction and making decisions regarding next steps.
     * JWT will be empty if validate was not successful
     *
     * @param session
     * @param validateResponse
     * @param serverJWT
     */
    -(void)cardinalSession:(CardinalSession *)session stepUpDidValidateWithResponse:(CardinalResponse *)validateResponse serverJWT:(NSString *)serverJWT{
       
    }
  
@end

If Continue
is called in the same class, call the method shown in the following example to start StepUpFlow
.

Cardinal.continue Call in the Same Class (Objective-C)

[session continueWithTransactionId: @"[TRANSACTION_ID]"
                           payload: @"[PAYLOAD]"
               didValidateDelegate: self];

Swift Examples

Cardinal session continue (iOS SDK - Swift)

class YourViewController:CardinalValidationDelegate {
  
    /**
     * This method is triggered when the transaction has been 
     * terminated.This is how SDK hands back
     * control to the merchant's application. This method will
     * include data on how the transaction attempt ended and
     * you should have your logic for reviewing the results of
     * the transaction and making decisions regarding next steps.
     * JWT will be empty if validate was not successful
     *
     * @param session
     * @param validateResponse
     * @param serverJWT
     */
    func cardinalSession(cardinalSession session: CardinalSession!, stepUpValidated validateResponse: CardinalResponse!, serverJWT: String!) {
        
    }
 
}

If Continue
is called in the same class, call the method shown in the example below to start StepUpFlow
.

Cardinal.continue Call in the Same Class (Swift)

session.continueWith(transactionId: "[TRANSACTION_ID]", payload: "[PAYLOAD]", validationDelegate: self)

When necessary, the SDK displays the authentication window and the customer enters their authentication information.
