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.
