A Converge terminal has two surcharge related properties: switch for allowing surcharge and surcharge percentage. CSDK gets the properties as a part of account information retrieval from Converge during initialization. The following code examples demonstrate how a POS system can obtain the surcharge properties from CSDK.

## Code Samples

### CWS 

```json
// OpenPaymentGateway response
// In this example, two surcharge attributes are added to accountInfo
// "isCreditSurchargeAllowed":true,
// "creditSurchargePercent":2.55
Response
{
 "requestId":"836703218",
 "statusDetails":"REQUEST_ACCEPTED",
 "data": {
 "paymentGatewayCommand": {
 "completed":true,
 "eventQueue":[],
 "openPaymentGatewayData": {
 "result":"SUCCESS",
 "paymentGatewayId":"fe2aef5a-7b06-4122-95b9-1d9d95c9424d"
 },
 "accountInfo": {
 "businessEmail":"a@b.com",
 "city":"",
 "address1":"",
 "postalCode":"",
 "isCvvEnabled":false,
 "stateProvince":"",
 "isCreditSurchargeAllowed":true,
 "creditSurchargePercent":2.55,
 "isAvsEnabled":false,
 "isGratuitySupported":false,
 "name":"Joe",
 "currencyCode":"USD",
 "marketSegment":"RETAIL"
 }
 }
 }
}
```

### Java 

```java
// In the following callback interface method ECLAccountInformationRetrievalListener.accountInformationRetrievalDidSucceed(...) implementation
// First get terminal configuration (ECLTerminalConfiguration) from account interface (ECLAccountInterface).
// Then retrieve surcharge preference (ECLSurchargePreference) from the terminal configuration.
// Two properties are defined for the surcharge preference:
// A boolean variable holding the state for the terminal allowing surcharge.
// A double variable holding the surcharge percentage.
@Override
public void accountInformationRetrievalDidSucceed(ECLAccountInterface eclAccountInterface,
 ECLAccountInformation accountInformation)
{
 activity.accountInfo = accountInformation;
 activity.displayMessageInProgressView("Account Info Retrieved:", false);
 activity.displayMessageInProgressView("name: " + accountInformation.getName(), false);
 activity.displayMessageInProgressView("currency: " + accountInformation.getCurrencyCode(), false);
 
 ECLTerminalConfiguration terminalConfig = eclAccountInterface.getTerminalConfiguration();
 if (terminalConfig != null)
 {
 ECLSurchargePreference surchargePreference = terminalConfig.getSurchargePreference();
 if (surchargePreference != null)
 {
 activity.displayMessageInProgressView("Surcharge Allowd: " + surchargePreference.isAllowCreditSurcharge(), false);
 if (surchargePreference.isAllowCreditSurcharge())
 {
 activity.displayMessageInProgressView("Surcharge Percentage: " + surchargePreference.getCreditSurchargePercent().doubleValue(), false);
 }
 }
 }
}
```

### Objective-C (iOS) 

```objc
// In the [ECLAccountInformationRetrievalDelegate accountInformationRetrievalDidSucceed:accountInformation:] method implementation
// Retrieve surcharge preference (ECLSurchargePreference) from the ECLAccountInformation.
// Two properties are defined for the surcharge preference:
// A BOOL variable indicating whether the account is configured to allow surcharge.
// An NSDecimalNumber variable holding the surcharge percentage.
+ (void)accountInformationRetrievalDidSucceed:(id<ECLAccountProtocol>)account accountInformation:(ECLAccountInformation *)accountInformation {
 BOOL surchargeAllowed = [accountInformation.surchargePreference creditSurchargeAllowed];
 [self addStatusString:[NSString stringWithFormat:@"Surcharge: %@\n", surchargeAllowed ? @"YES" : @"NO"]];
 if (surchargeAllowed) {
 [self addStatusString:[NSString stringWithFormat:@"Surcharge Percent: %.02f%%\n", [[accountInformation.surchargePreference creditSurchargePercent] doubleValue]]];
 }
}
```

### C\# 

```c#
// Property AccountInfo of Object OpenPaymentGatewayResults has two new properites for holding surcharge properties:
// isCreditSurchargeAllowed -- the state for the terminal allowing surcharge
// creditSurchargePercent -- the surcharge percentage
private void updateAccountInformation(AccountInfo acctInfo)
{
 Log("----- AccountInfo -----");
 
 Log(String.Format("Credit Surcharge Allowed: {0}", acctInfo.isCreditSurchargeAllowed));
 if (acctInfo.isCreditSurchargeAllowed)
 {
 Log(String.Format("Credit Surcharge Percent: {0}", acctInfo.creditSurchargePercent));
 }
}
```
