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 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.
