Dear Expert, In VTS Implementation, while storing the provisioned token in the mobile application, when we call storeProvisionedToken API of Visa SDK to store the ProvisionResponse from MAP, we are getting VisaPaymentSDKException - SDK Session is unavailable.  We do not have any references regarding handling the SDK session Exception. Can anyone help us to advise on the resolution please. The complete error stacktrace log is: visaPaymentSDK!!.storeProvisionedToken(context, provisionResponse, enrollmentId)   E/AndroidRuntime: FATAL EXCEPTION: main     Process: com.neurogine.cbc.app, PID: 31221     com.visa.cbp.sdk.facade.exception.VisaPaymentSDKException: SDK session is unavailable.         at com.visa.cbp.sdk.ᵎ.storeProvisionedToken(Unknown Source:305)         at com.neurogine.modules.visa.VisaUtils.storeProvisionedToken(VisaUtils.kt:195)         at com.neurogine.modules.app.nfc.NfcFragment$provisionTokenRequest$1.onSuccess(NfcFragment.kt:159)         at webservice.apis.visa.ProvisionTokenAPI$execute$1.onSuccess(ProvisionTokenAPI.kt:37)         at webservice.apis.visa.ProvisionTokenAPI$execute$1.onSuccess(ProvisionTokenAPI.kt:34)         at webservice.helpers.RetroFitCaller.responseSuccess(RetroFitCaller.java:116)         at webservice.helpers.RetroFitCaller.onResponse(RetroFitCaller.java:85)         at retrofit2.DefaultCallAdapterFactory$ExecutorCallbackCall$1.lambda$onResponse$0$DefaultCallAdapterFactory$ExecutorCallbackCall$1(DefaultCallAdapterFactory.java:82)         at retrofit2.-$$Lambda$DefaultCallAdapterFactory$ExecutorCallbackCall$1$3wC8FyV4pyjrzrYL5U0mlYiviZw.run(Unknown Source:6)         at android.os.Handler.handleCallback(Handler.java:873)         at android.os.Handler.dispatchMessage(Handler.java:99)         at android.os.Looper.loop(Looper.java:193)         at android.app.ActivityThread.main(ActivityThread.java:6702)         at java.lang.reflect.Method.invoke(Native Method)         at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493)         at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:911)   Thank You Paul ...

Dear Experts, In VTS Implementation, for enrollDevice API, what will be the device cert values to be passed. deviceCerts": [ { "certFormat": "X509", "certUsage": "CONFIDENTIALITY", "certValue": "????"}. we generated the master_cert.pem. In the API reference guide, the cert value is mentioned as in PEM format/ Base64URL safe encoded. It is not clear that how to generate the cert value. Please help me to resolve this issue.  Thank You Paul ... View more

Dear Experts, VISA stores the Token in a secured format in the mobile local storage such as keystore/keychain using the API provided by VTS SDK. But when the mobile app is uninstalled, does VTS SDK take care of removing the tokens in the local storage?   Thank You Paul ... View more

Hello Visa Team, Does VTS support the offline data authentication (ODA) data replenishment scenarios. If so, how can the mobile application platform check on the token status and authenticate the validity.  Thank You Paul ... View more

Hello Visa Experts,   Our banking credit card mobile app will be integrated to VTS for tokenization of cards for payment purpose. As VTS APIs are restricted(yet to receive from Visa Team), I would like to know what are all the data to be sent from Mobile App to VTS. 1. PAN (Credit Card Number) 2. Token Key (Generated by VTS) 3. Biometric Fingerprint / Face ID / mPIN (this is required for banking host to authenticate, but does VTS require it) 4. ??? I assume VTS expects the MAP(Mobile Application Platform) to perform the authentication and just pass the PAN / Token information.  Appreciate your inputs on the Authentication of the Card used for payment.   Thank You Paul ...
