### Java 

This code sample demonstrates accessing the Converge account information during initialization. The code sample implements `ECLAccountInformationRetrievalListener` and passes the listener during initialization.

```java
public class CommerceAccountListener implements ECLConvergeAccountListener, ECLAccountInformationRetrievalListener
{

 ...

 @Override
 public void accountInformationRetrievalDidSucceed(ECLAccountInterface eclAccountInterface, ECLAccountInformation eclAccountInformation)
 {
 logger.info("Account info retrieved:");
 logger.info("name:" + eclAccountInformation.getName());
 logger.info("currency:" + eclAccountInformation.getCurrencyCode());
 logger.info("language: " + eclAccountInformation.getLanguageInformation().valueAsString());
 logger.info("Gratuity: " + eclAccountInformation.isGratuitySupported());
 logger.info("CVV: " + eclAccountInformation.isCvvEnabled());
 logger.info("AVS: " + eclAccountInformation.isAvsEnabled());
	logger.info("Healthcare: " + eclAccountInformation.isHealthcareEnabled());
	logger.info("Food Stamp: " + eclAccountInformation.isFoodStampEnabled());
	logger.info("Cash Benefit: " + eclAccountInformation.isCashBenefitEnabled());
	logger.info("DCC: " + eclAccountInformation.isDccEnabled());
	logger.info("Tokenization: " + eclAccountInformation.isTokenizationEnabled());
	logger.info("Terminal Status: " + eclAccountInformation.getTerminalStatus());
	logger.info("Supported Card Brands: " + eclAccountInformation.getSupportedCardBrands());
	logger.info("Is CSDK Enabled: " + eclAccountInformation.isCsdkEnabled());
 ECLTerminalConfiguration terminalConfig = eclAccountInterface.getTerminalConfiguration();
 if (terminalConfig != null)
 {
 logger.info("language: " + terminalConfig.getRemoteLanguage().valueAsString());
 ECLDebitNetworkPreferences debitPrefs = terminalConfig.getRemoteDebitNetworkPreferences();
 if (debitPrefs != null)
 {
 logger.info("Debit network preference (VISA): " + debitPrefs.getPreference(ECLCardBrand.VISA));
 logger.info("Debit network preference (MASTERCARD): " + debitPrefs.getPreference(ECLCardBrand.MASTERCARD));
 logger.info("Debit network preference (DISCOVER): " + debitPrefs.getPreference(ECLCardBrand.DISCOVER));
 }
 }
 commerceAccount.setEclAccountInformation(eclAccountInformation);
 }

 @Override
 public void accountInformationRetrievalDidFail(ECLAccountInterface eclAccountInterface, ECCError error)
 {
 logger.warning("Failed to get info");
 if (error instanceof ECLCommerceError)
 {
 logger.warning(((ECLCommerceError) error).getCode().name());
 }
 else if (error instanceof ECLConvergeError)
 {
 logger.warning(((ECLConvergeError) error).getCode().name());
 }
 else
 {
 logger.warning("error" + error.getLocalizedDescription());
 }
 }
}
```

This code sample demonstrates accessing the Converge account information using explicit calls.

```java
ECLAccountInterface account;

...

ECLAccountInformationRetrievalListener delegate = new ECLAccountInformationRetrievalListener()
{
 @Override
 public void accountInformationRetrievalDidSucceed(ECLAccountInterface account, ECLAccountInformation accountInformation)
 {
 logger.info("AVS: " + accountInformation.isAvsEnabled());
 }

 @Override
 public void accountInformationRetrievalDidFail(ECLAccountInterface account, ECCError eccError)
 {
 //Error handling
 }
};

if (account != null)
{
 account.retrieveAccountInformation(delegate);
}

```

### Objective-C (iOS) 

This code sample demonstrates accessing the Converge account information during initialization. The code sample implements `ECLAccountInformationRetrievalDelegate` and passes the delegate during initialization.

```objc
@interface AccountDelegate : NSObject <ECLAccountDelegate, ECLAccountInformationRetrievalDelegate>

...

+ (void)accountInformationRetrievalDidSucceed:(id<ECLAccountProtocol>)account accountInformation:(ECLAccountInformation *)accountInformation {
 [self.mainViewControllerReference addStatusString:@"Account Info Retrieval succeeded\n"];
 self.mainViewControllerReference.accountInformation = accountInformation;
}


+ (void)accountInformationRetrievalDidFail:(id<ECLAccountProtocol>)account error:(NSError *)error {
 [self.mainViewControllerReference addStatusString:[NSString stringWithFormat:@"Account Info Retrieval failed: %@\n", [error debugDescription]]];
}
```

This code sample demonstrates accessing the Converge account information using explicit calls.

```objc
[account retrieveAccountInformation:account codeBlock:^(id<ECLAccountProtocol> account, ECLAccountInformation *info, NSError *error) {
 // we are on the callback queue so run on our queue
 if (error == nil) {
 ECL_LOG_INFO(@"prvProcessTransaction: retrieved account info");
 //Do something with the account info
 } else {
 ECL_LOG_INFO(@"prvProcessTransaction: failed to retrieve account info");
 [delegate transactionDidFail:transaction using:tender errors:@[ error ]];
 }
}];

```

### C\# 

This code sample demonstrates accessing the Converge account information when opening the payment gateway.

#### Request

```c#
OpenPaymentArgs obea = new OpenPaymentArgs();
```

#### Response

```c#
public void MyOpenPaymentGatewayComplete(OpenPaymentGatewayResults ober)
{
 ...

 AccountInfo accountInfo = ober.AccountInfo;
 if (null != accountInfo)
 {
 //do something with the account info
 }

 ...
}
```

## Validate BMS credentials
POS can call this to check that BMS Credentials (bmsUsername and bmsPassword) are valid.


### Code samples

#### CWS 

##### Request

```json
{
 "method" : "validateBmsCredentials",
 "requestId" : "7571358",
 "targetType" : "paymentGatewayConverge",
 "version" : "1.0",
 "parameters" : {
 "paymentGatewayId" : "6f95a650-b56f-4b45-88d6-b2f53d55e4f6"
 }
}
```

##### Response - credentials are valid

```json
{
 "requestId" : "7571358",
 "statusDetails" : "REQUEST_ACCEPTED",
 "data" : {
 "paymentGatewayCommand" : {
 "completed" : true,
 "eventQueue" : [ ],
 "paymentTransactionData" : {
 "result" : "SUCCESS"
 },
 "warnings" : [ ]
 }
 }
}
```

##### Response - credentials are invalid 

```json
{
 "requestId" : "7571361",
 "statusDetails" : "REQUEST_ACCEPTED",
 "data" : {
 "paymentGatewayCommand" : {
 "completed" : true,
 "eventQueue" : [ ],
 "paymentTransactionData" : {
 "result" : "FAILED",
 "errors" : [ "ECLCommerceError ECLAccountInvalidCredentials" ]
 },
 "warnings" : [ ]
 }
 }
}
```

#### Java

Create an instance of *com.elavon.commerce.ECLAccountValidationListener*, as shown below.

```java
// The following code is copied from MainActivity.java in the sample application code.
// The code displays results on UI.
 
ECLAccountValidationListener delegate = new ECLAccountValidationListener()
{
 @Override
 public void accountDidValidate(ECLAccountInterface eclAccountInterface)
 {
 displayMessageInProgressView("validate BMS Credentials - succeeded", false);
 }
 
 @Override
 public void accountDidFailToValidate(ECLAccountInterface eclAccountInterface, ECCError eccError)
 {
 displayErrorInProgressView("validate BMS Credentials - failed", eccError);
 }
};
```

Then pass the instance to method `validateBmsCredentials` on interface `com.elavon.commerce.ECLAccountInterface`. CSDK internally validates the combination of bmsUsername and bmsPassword provided by the POS.

If the BMS cannot validate the credentials, *ECLCommerceError.Codes.ECLAccountInvalidCredentials* will be returned in *ECLAccountValidationListener.accountDidFailToValidate*.

```java
TransactionSavedState.INSTANCE.account.validateBmsCredentials(delegate);
```

#### Objective-C

Create a class implementing the ECLAccountValidationDelegate protocol and implement the methods accountDidValidate and accountDidFailToValidate, as shown below.

```objc
@interface ValidateBmsCredentialsDelegate : NSObject<ECLAccountValidationDelegate>
 
@property MainViewController *mainViewController;
 
@end
 
@implementation ValidateBmsCredentialsDelegate
 
- (void)accountDidValidate:(id<ECLAccountValidationDelegate>)delegate {
 [_mainViewController addStatusString:@"BMS credentials validated\n"];
}
 
- (void)accountDidFailToValidate:(id<ECLAccountValidationDelegate>)delegate error:(NSError *)error {
 [_mainViewController addStatusString:[NSString stringWithFormat:@"BMS credentials failed to be validated: %@\n", [error debugDescription]]];
}
 
@end
```

Then, pass an instance of the delegate to the method *validateBmsCredentials* of protocol *ECLAccountProtocol*. CSDK internally validates the combination of bmsUsername and bmsPassword provided by the POS.

If the BMS cannot validate the credentials, an ECLError with code *ECLAccountInvalidCredentials* will be returned in accountDidFailToValidate.

```objc
// inside MainViewController implementation
 
id<ECLAccountValidationDelegate> delegate = [[ValidateBmsCredentialsDelegate alloc] initWithMainViewController:self];
[_account validateBmsCredentials:delegate];
```

#### C\#

```c#
// Asynchronous
StartValidateBmsCredentials(String paymentGatewayId, NotifyCWSEvent ne, PaymentTransactionComplete ptc) 
 
// Synchronous
PaymentTransactionResults results = m_CWS.ValidateBmsCredentials(String paymentGatewayId);
MyValidateBmsCredentialsComplete(results, results.Warnings);
 
// Do something with the response
public void MyValidateBmsCredentialsComplete(PaymentTransactionResults paymentResults, String[] warnings)
{
 lock (myPaymentCompleteLock)
 {
 Log("----------- Validate BMS Credentials Complete ------------");
```
