Enable App to App service
The following diagram illustrates the flows of the App-to-App APIs for payment card push provisioning
Figure: Flows of push provisioning APIs
The main classes involved are:
Samsung Pay
– for fetching Samsung Pay app status and wallet information on the device.PaymentManager
– for card provisioning and invoking Favorite Cards payment functionalities.CardManager
– for payment card management.WatchManager
– for all functions related to Samsung Pay Watch.
Let’s now take a look at how each one works in the context of your bank app.
Requesting registered card list in the Samsung Pay
The'getAllCards()
method of the CardManager
class is used to request a list of all cards currently registered/enrolled in Samsung Pay on the same device running the issuer’s app. To succeed, the issuer app must pass valid PartnerInfo to 'CardManager' for caller verification. 'cardFilter' narrows the card list returned by Samsung Pay to the issuerName specified. Please be noted that getSamsungPayStatus()
must be called before getAllCards()
. getAllCards()
could not return a cards list when getSamsungPayStatus()
responds with a code other than SPAY_READY
.
WatchManager
class instead of the CardManager class.As of API level (SDK version) 1.4, cardFilter
retrieves this information from the Samsung Pay Developers portal. Certain issuers may need to register multiple ISSUER NAME(s) with the portal, depending on their app and/or the requirements of their token service provider (TSP). The getAllCards()
parameter cardFilter
matches the ISSUER NAME(s)
specified with those registered in the portal. Only complete matches are returned.
This method is typically called when your partner app wants to check the card status. It does not need to be called every time the partner app resumes. Therefore, you should create the card list with the 'onCreate()' method, rather than the 'onResume()' method.
The result of a getAllCards()
call is delivered to GetCardListener
, which provides the following events:
onSuccess()
- called when the operation succeeds; provides the list of all filtered cards and their status. Card information includes cardId, cardStatus, and extra cardInfo data.onFail()
- called when the operation fails.
Here’s an example of how to use the 'getAllCards()' API method in your issuer app.
Bundle cardFilter = new Bundle();
// Since API level 1.4, cardFilter param is ignored. Partner does not need to use it here.
// It is retrieved from the Samsung Pay Developers portal
cardFilter.putString(CardManager.EXTRA_ISSUER_NAME, issuerName);
cardManager.getAllCards(cardFilter, new GetCardListener() {
@Override
public void onSuccess(List<Card> cards){
// Getting card status is success
if (cards == null || cards.isEmpty()){
Log.e(TAG,"No card is found");
return;
} else {
// Perform operation with card data
for (Card s:cards) {
Log.d(TAG,"CardId: "+ s.getCardId()+"CardStatus "+s.getCardStatus());
// Get Extra card data
if (s.getCardInfo() != null) {
String cardId = s.getCardId(); // Since API level 2.13, ID from card network.
String last4FPan = s.getCardInfo().getString(CardManager.EXTRA_LAST4_FPAN);
String last4DPan = s.getCardInfo().getString(CardManager.EXTRA_LAST4_DPAN);
String cardType = s.getCardInfo().getString(CardManager.EXTRA_CARD_TYPE);
String cardIssuerName = s.getCardInfo().getString(CardManager.EXTRA_ISSUER_NAME);
Log.d(TAG,"last4FPan:"+last4FPan+" last4DPan:"+ last4DPan + " CardId: "+ cardId);
}
}
}
}
@Override
public void onFail(int error, Bundle errorData) {
// Getting card status is failed
}
});
Getting wallet information
The SamsungPay
class provides the getWalletInfo()
API method, which is called to request wallet information from the Samsung Pay app prior to calling the addCard()
API, when you want to avoid duplicate provisioning. Your issuer app uses this information to uniquely identify the user and the Samsung Pay app on a particular device (wallet device management ID, device ID, and wallet user ID).
WatchManager
class instead of the CardManager class.void getWalletInfo(List<String> keys, StatusListener callback)
The following example demonstrates how to use it.
// Set the serviceId assigned by the Samsung Pay Developers portal during service creation
String serviceId = "sampleServiceId";
Bundle bundle = new Bundle();
bundle.putString(SamsungPay.EXTRA_ISSUER_NAME,"issuer name");
bundle.putString(SamsungPay.PARTNER_SERVICE_TYPE,SamsungPay.ServiceType.APP2APP.toString());
PartnerInfo pInfo = new PartnerInfo(serviceId, bundle);
SamsungPay samsungPay = new SamsungPay(context, pInfo);
// Add bundle keys to get wallet information from Samsung Pay.
// This information can be delivered to the Partner Server for an eligibility check.
ArrayList<String> keys = new ArrayList<>();
keys.add(SamsungPay.WALLET_USER_ID);
keys.add(SamsungPay.DEVICE_ID);
samsungPay.getWalletInfo(keys, new StatusListener() {
@Override
public void onSuccess ( int status, Bundle walletData){
// Log.d(TAG, "doWalletInfo onSuccess callback is called");
// For VISA, deviceID can be set to "clientDeviceID" as defined by VISA
String deviceId = walletData.get(SamsungPay.DEVICE_ID);
// For VISA, walletUserId can be set to "clientWalletAccountID" as defined by VISA
String walletUserId = walletData.get(SamsungPay.WALLET_USER_ID);
}
@Override
public void onFail ( int errorCode, Bundle errorData){
Log.e(TAG, "onFail callback is called, errorCode: " + errorCode);
// Check the extra error codes in the errorData bundle for all the reasons in
// SamsungPay.EXTRA_ERROR_REASON, when provided
}
}
Adding a card to Samsung Pay
Your issuer app calls the 'addCard()' API method of CardManager
to add a card to Samsung Pay. By providing the required card details, your app can make it convenient and easy for users to add their bank-issued debit/credit cards to Samsung Pay directly from your app without additional steps, like switching between apps.
CardManager
class.For most issuers, getWalletInfo()
suffices for requesting current wallet information. The response from Samsung Pay tells the issuer app whether or not the user’s card has already been added to Samsung Pay or is ineligible for provisioning. It is therefore recommended that you call getWalletInfo()
before displaying the Add to Samsung Pay button. If the card is eligible, display the “add” button and, if the user taps it, call addCard()
.
The 'addCard()' result is delivered to AddCardListener
, which provides the following events:
onSuccess()
- called when the operation succeeds; provides information and status regarding the added card.onFail()
- called when the operation fails; returns the error code and extra bundle data such asEXTRA_ERROR_REASON
orEXTRA_REQUEST_ID
(if provided).onProgress()
- called to indicate the current progress of the 'addCard()' operation; can be used to show a progress bar to the user in the issuer app. This callback is supported for TSM solution issuers in China and Spain.
Here’s an example of how to use the addCard()
API method in your issuer app.
String cardType = Card.CARD_TYPE_CREDIT;
String tokenizationProvider = AddCardInfo.PROVIDER_ABCD;
// Samsung Pay does not provide detailed payload information; generate the provisioning payload in
// accordance with your card network specifications
String testPayload = "ThisIsTestPayloadCardInfo1234567890";
Bundle cardDetail = new Bundle();
cardDetail.putString(AddCardInfo.EXTRA_PROVISION_PAYLOAD, testPayload);
AddCardInfo addCardInfo = new AddCardInfo(cardType, tokenizationProvider, cardDetail);
cardManager.addCard(addCardInfo, new AddCardListener() {
@Override
public void onSuccess(int status, Card card) {
Log.d(TAG, "onSuccess callback is called");
}
@Override
public void onFail(int error, Bundle errorData ) {
Log.d(TAG, "onFail callback is called");
check some extra error codes in the errorData bundle
such as SamsungPay.EXTRA_ERROR_REASON or SamsungPay.EXTRA_REQUEST_ID (if provided).
}
@Override
public void onProgress(int currentCount, int totalCount, Bundle bundleData) {
Log.d(TAG,"onProgress callback is called : " + currentCount + " / " + totalCount);
}
});
