TSYSSettle Class

Properties Methods Events Config Settings Errors

The TSYSSettle class is used to do a Batch Settlement on all transactions that were successfully authorized with the TSYSECOMMERCE or TSYSRETAIL classes. This class may also send Level II and Level III Corporate Purchasing Card data for better interchange rates.

Syntax

dpaymentssdk.Tsyssettle

Remarks

This class allows for a direct, secure connection to the Vital/TSYS gateway through a standard Internet connection. This class can be integrated into web pages or stand-alone Point Of Sale applications. Because all TLS/SSL communications are handled inside the class, any application or web page can be deployed without the need for expensive dedicated TLS/SSL servers. The TSYSSettle class is used to settle all transactions previously authorized by the TSYSECommerce or TSYSRetail class. When a transaction is authorized, money in the customer's account is blocked and tagged for the merchant. However, funds do not actually change hands at this point. When transactions are settled with the TSYSSettle class the funds are deducted from the customer's account and added to the merchant's. It is essential that the authorized transactions are properly recorded and resent later in a Batch Settlement.

To send a Batch Settlement, first the user must fill out the Merchant properties with the same information contained in the authorizing class's Merchant properties.

TSYSSettle.Merchant.BankId = "999995" TSYSSettle.Merchant.CategoryCode = "5999" TSYSSettle.Merchant.Name = "test merchant" TSYSSettle.Merchant.Number = "123456789012" TSYSSettle.Merchant.City = "Beverly Hills" TSYSSettle.Merchant.State = "CA" TSYSSettle.Merchant.StoreNumber = "5999" TSYSSettle.Merchant.TerminalNumber = "1515" TSYSSettle.Merchant.Zip = "90210"

Additionally, the AgentBankNumber, AgentChainNumber, TerminalId, BatchNumber, and IndustryType must be set. Note that the TerminalId is fundamentally different from the TerminalNumber. The TerminalNumber is used to identify a unique terminal (PC, server, whatever) within a merchant location. The TerminalId, also known as the "V Number", is used for point-of-sale tracking. TSYSSettle.AgentBankNumber = "000000" TSYSSettle.AgentChainNumber = "111111" TSYSSettle.TerminalId = "00000001" TSYSSettle.BatchNumber = 15 TSYSSettle.IndustryType = itRetail

At this point, you are ready to add transactions to the batch settlement. Each successfully authorized transaction to be settled must be added to the DetailRecords collection. The DetailRecords collection contains TSYSRecordType types, which consist of a a DetailAggregate and AddendumAggregate field. The DetailAggregate field should be set with the XML aggregate returned from the TSYSRetail, TSYSECommerce, or TSYSDetailRecord class's GetDetailAggregate method. The AddendumAggregate is used when passing additional commercial card addendum data with the settlement, and is not used for regular credit card transactions. TSYSSettle.DetailRecords.Add(new TSYSRecordType(TSYSRetail.GetDetailAggregate())); or TSYSSettle.DetailRecords.Add(new TSYSRecordType()); TSYSSettle.DetailRecords[0].DetailAggregate = TSYSRetail.GetDetailAggregate();

Finally, call the SendSettlement method.

TSYSSettle.SendSettlement()

If the transaction is successful, the Code will contain "GB", which indicates a "Good Batch". You should check that the NetDeposit and RecordCount match the NetDeposit and RecordCount fields.

If the transaction is not successful and you receive an "RB" Code (indicating a "Rejected Batch") the class throws an exception. You may inspect the Data. DataFieldNumber, RecordType, SequenceNumber, and ErrorType properties for more information concerning why the batch was rejected. After either fixing this record to resolve the error, or removing the record from the batch, the entire batch must be resubmitted. When resubmitting a batch that was previously rejected, the BatchNumber must be set to the same value that was originally used. It is critical that the same BatchNumber value is used to avoid duplicate charges.

Thousands of detail records may be settled in the above manner, just by adding transactions to the DetailRecords collection. However it is recommended that Batch Settlements be kept relatively small - around 100 transactions or so - to decrease the number of records that must be resent in the event of an error.

To Void a transaction that has been authorized but has not yet been settled, simply do not include it in the batch settlement. The block on the cardholder's account will clear automatically. Credits and forced transactions may be created using the TSYSDetailRecord class and settled in the same manner.

To add Level II or Level III data to the settled transactions, use the AddendumAggregate field and the TSYSLevel2 or TSYSLevel3 classs.

Note that the IndustryType from the TSYSSettle class MUST match the detail record aggregate of EACH transaction that is added to the settlement. You cannot mix industry types in a batch - you must settle a separate batch for each industry type.

This is a Header Property, and needs to be set once for a single Batch Settlement transaction.

Batch Property (TSYSSettle Class)

Contains information about the batch settlement, as computed by the class.

Syntax


public TSYSBatchInfo getBatch();

Remarks

When building a settlement, the class will calculate the fields in the table below.


CashBackTotal	Total amount of cash back for all transactions in the batch.
HashingTotal	Total of purchases plus refunds.
NetDeposit	Total of purchases minus refunds.
RecordCount	Total number of records sent including Header, Parameter, and Trailer. Should be compared to the response RecordCount.

This property is read-only.

Please refer to the TSYSBatchInfo type for a complete list of fields.

BatchNumber Property (TSYSSettle Class)

Sequence number of this batch transaction.

Syntax


public int getBatchNumber();


public void setBatchNumber(int batchNumber);

Default Value

Remarks

This property contains a three digit batch sequence number generated by the Point of Sale (POS) device. The batch number must be within the range "001" to "999". If the POS device is automatically incrementing the batch number, it should automatically advance the number from "999" to "001"("000" is invalid). Batch numbers must not be reused or repeated within 5 consecutive days.

This is a Header Property, and needs to be set once for a single Batch Settlement transaction.

If the transaction is successful, the Code will contain "GB", which indicates a "Good Batch". You should check that the NetDeposit and RecordCount match the NetDeposit and RecordCount fields.

DetailRecords Property (TSYSSettle Class)

Collection of detail records to send in the settlement.

Syntax


public TSYSRecordTypeList getDetailRecords();


public void setDetailRecords(TSYSRecordTypeList detailRecords);

Remarks

Each TSYSRecordType object in the collection specifies an xml aggregate representing the transaction to be settled. The TSYSRecordType may also specify an addenda aggregate for sending Level2 or Level2 and Level3 data. The XML aggregate to be settled is generated from the TSYSRetail, TSYSECommerce, TSYSGiftCard, TSYSBenefit, or TSYSDetailRecord class.

The following example shows how to add a detail record to the collection. TSYSEcommerce1.Authorize(); TSYSSettle.DetailRecords.Add(new TSYSRecordType(TSYSEcommerce1.GetDetailAggregate()));

Xml aggregates are used instead of directly passing Objects because it is easy to store XML aggregates in a database after authorization, and then retrieve them for settlement at the end of the business day.

Please refer to the TSYSRecordType type for a complete list of fields.

Error Property (TSYSSettle Class)

Contains information about settlement errors.

Syntax


public TSYSBatchErrorInfo getError();

Syntax


public Certificate getSSLAcceptServerCert();


public void setSSLAcceptServerCert(Certificate SSLAcceptServerCert);

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Please note that this functionality is provided only for cases where you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

Please refer to the Certificate type for a complete list of fields.

SSLCert Property (TSYSSettle Class)

The certificate to be used during SSL negotiation.

Syntax


public Certificate getSSLCert();


public void setSSLCert(Certificate SSLCert);

Remarks

The digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the Encoded field to the encoded certificate. To select a certificate, use the store and subject fields.

Please refer to the Certificate type for a complete list of fields.

SSLProvider Property (TSYSSettle Class)

This specifies the SSL/TLS implementation to use.

Syntax


public int getSSLProvider();


public void setSSLProvider(int SSLProvider);


Enumerated values:
  public final static int sslpAutomatic = 0;
  public final static int sslpPlatform = 1;
  public final static int sslpInternal = 2;

Default Value

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:


0 (sslpAutomatic - default)	Automatically selects the appropriate implementation.
1 (sslpPlatform)	Uses the platform/system implementation.
2 (sslpInternal)	Uses the internal implementation.

Additional Notes

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.

SSLServerCert Property (TSYSSettle Class)

The server certificate for the last established connection.

Syntax


public Certificate getSSLServerCert();

Remarks

SSLServerCert contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

Please refer to the Certificate type for a complete list of fields.

TerminalId Property (TSYSSettle Class)

Contains number to accommodate a POS device tracking number.

Syntax


public String getTerminalId();


public void setTerminalId(String terminalId);

"00000001"

Remarks

This eight digit field contains the number to accommodate a Point Of Sale (POS) device tracking number. This field is also known as the "V" number. Unless otherwise specified by the merchant's bank or processor, this field should be defaulted to "00000001".

Note: If specified, the "V" alpha character must be changed to a numeric 7 when setting this property.

This is a Parameter Property, and need only be set once for a single Batch Settlement transaction.

Timeout Property (TSYSSettle Class)

A timeout for the class.

Syntax


public int getTimeout();


public void setTimeout(int timeout);

Default Value

Remarks

If Timeout is set to a positive value, and an operation cannot be completed immediately, the class will retry the operation for a maximum of Timeout seconds.

The default value for Timeout is 30 (seconds).

Config Method (Tsyssettle Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Interrupt Method (Tsyssettle Class)

Syntax

public void interrupt();

Remarks

This method interrupts any processing that the class is currently executing.

Reset Method (Tsyssettle Class)

Resets all the properties of the entire settlement to their default values.

Syntax

Remarks

This method resets the Header and Parameter Record properties to default values, and clears all Detail Records. To clear only the Detail Records (leaving Header and Parameter records intact) clear the DetailRecords collection.

SendSettlement Method (Tsyssettle Class)

Begins a Batch Settlement transaction with the transaction server.

Syntax

public void sendSettlement();

Remarks

This begins a Batch Settlement transaction. The Header Record, Parameter Record, all transaction Detail Records, and the computed Trailer Record are sent sequentially to the Vital/TSYS host.

If the transaction is successful, the Code will contain "GB", which indicates a "Good Batch". You should check that the NetDeposit and RecordCount match the NetDeposit and RecordCount fields.

Connected Event (Tsyssettle Class)

Fired immediately after a connection completes (or fails).

Syntax

public class DefaultTsyssettleEventListener implements TsyssettleEventListener {
  ...
  public void connected(TsyssettleConnectedEvent e) {}
  ...
}

public class TsyssettleConnectedEvent {
  public int statusCode;
  public String description;
}

Remarks

If the connection is made normally, StatusCode is 0, and Description is "OK".

If the connection fails, StatusCode has the error code returned by the TCP/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

Please refer to the Error Codes section for more information.

DataPacketIn Event (Tsyssettle Class)

Fired when receiving a data packet from the transaction server.

Syntax

public class DefaultTsyssettleEventListener implements TsyssettleEventListener {
  ...
  public void dataPacketIn(TsyssettleDataPacketInEvent e) {}
  ...
}

public class TsyssettleDataPacketInEvent {
  public byte[] dataPacket;
}

Remarks

This event fires when a packet is received. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or to extract additional response properties beyond the scope of this class.

DataPacketOut Event (Tsyssettle Class)

Fired when sending a data packet to the transaction server.

Syntax

public class DefaultTsyssettleEventListener implements TsyssettleEventListener {
  ...
  public void dataPacketOut(TsyssettleDataPacketOutEvent e) {}
  ...
}

public class TsyssettleDataPacketOutEvent {
  public byte[] dataPacket;
}

Remarks

This event fires right before each data packet is sent. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or may be modified to support additional features beyond the scope of this class.

Disconnected Event (Tsyssettle Class)

Fired when a connection is closed.

Syntax

public class DefaultTsyssettleEventListener implements TsyssettleEventListener {
  ...
  public void disconnected(TsyssettleDisconnectedEvent e) {}
  ...
}

public class TsyssettleDisconnectedEvent {
  public int statusCode;
  public String description;
}

Remarks

If the connection is broken normally, StatusCode is 0, and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by Winsock. Description contains a description of this code. The value of StatusCode is equal to the value of the Winsock error.

Please refer to the Error Codes section for more information.

Error Event (Tsyssettle Class)

Information about errors during data delivery.

Syntax

public class DefaultTsyssettleEventListener implements TsyssettleEventListener {
  ...
  public void error(TsyssettleErrorEvent e) {}

}

public class TsyssettleErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired in case of exceptional conditions during message processing.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

SSLServerAuthentication Event (Tsyssettle Class)

Fired after the server presents its certificate to the client.

Syntax

public class DefaultTsyssettleEventListener implements TsyssettleEventListener {
  ...
  public void SSLServerAuthentication(TsyssettleSSLServerAuthenticationEvent e) {}
  ...
}

public class TsyssettleSSLServerAuthenticationEvent {
  public byte[] certEncoded;
  public String certSubject;
  public String certIssuer;
  public String status;
  public boolean accept;
}

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (Tsyssettle Class)

Fired when secure connection progress messages are available.

Syntax

public class DefaultTsyssettleEventListener implements TsyssettleEventListener {
  ...
  public void SSLStatus(TsyssettleSSLStatusEvent e) {}
  ...
}

public class TsyssettleSSLStatusEvent {
  public String message;
}

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

Certificate Type

This is the digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

EffectiveDate
String (read-only)
Default Value: ""

This is the date on which this certificate becomes valid. Before this date, it is not valid. The following example illustrates the format of an encoded date:

23-Jan-2000 15:00:00.

Encoded
String
Default Value: ""

This is the certificate (PEM/Base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.

EncodedB
byte[]
Default Value: ""

This is the certificate (PEM/Base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

ExpirationDate
String (read-only)
Default Value: ""

This is the date the certificate expires. After this date, the certificate will no longer be valid. The following example illustrates the format of an encoded date:

23-Jan-2001 15:00:00.

ExtendedKeyUsage
String
Default Value: ""

This is a comma-delimited list of extended key usage identifiers. These are the same as ASN.1 object identifiers (OIDs).

Fingerprint
String (read-only)
Default Value: ""

This is the hex-encoded, 16-byte MD5 fingerprint of the certificate. This property is primarily used for keys which do not have a corresponding X.509 public certificate, such as PEM keys that only contain a private key. It is commonly used for SSH keys.

The following example illustrates the format: bc:2a:72:af:fe:58:17:43:7a:5f:ba:5a:7c:90:f7:02

FingerprintSHA1
String (read-only)

public TSYSBatchErrorInfo();

TSYSBatchInfo Type

Contains information about the batch settlement as computed by the class.

Remarks

When building a settlement, the class will calculate the fields listed below:

Fields

CashBackTotal
String (read-only)
Default Value: "0000000000000000"

Total amount of cash back for all transactions in the batch.

This field contains the total of all cash back amounts reflected in the settlement batch. Note that only Debit Cards, Gift Cards, and EBT cards allow for cash back to be returned to the customer. For normal credit card transactions, this field will be defaulted to zeros.

This is a Trailer field, and is automatically computed by the class.

This amount is to be presented with an implied decimal point. For example, US $10.00 must be represented as 1000, and $0.10 is likewise simply 10. The allowable number of significant digits as well as the positioning of any implied decimal point is dictated by the designated CurrencyCode configuration setting. In the United States (default), the number of allowable significant digits is seven. Thus the maximum TransactionAmount is "9999999", yielding a US dollar amount of $99,999.99. This field may not contain a negative number.

HashingTotal
String (read-only)
Default Value: "0000000000000000"

Total of purchases plus credits.

This 16-digit field contains the batch hashing total generated by the terminal. The hashing total is generated by adding the absolute value of all detail record amounts. Void and purchase return settlement amounts are treated as positive and added to the total, not subtracted from it.

This is a Trailer field, and is automatically computed by the class.

NetDeposit
String (read-only)
Default Value: "0000000000000000"

Total of purchases minus credits.

This 16-digit field contains the net deposit generated by the terminal. The net deposit total is generated by adding the settlement amounts of all detail transaction records and subtracting credit/refund amounts from it.

This is a Trailer field, and is automatically computed by the class.

// First authorize the credit card TSYSECommerce1.TransactionAmount = "53"; TSYSECommerce.Authorize(); // Then, put the result into the settlement component TSYSSettle.DetailRecords.Add(new TSYSRecordType()); TSYSSettle.DetailRecords[0].DetailAggregate = TSYSECommerce.GetDetailAggregate(); // Now build the Level3 Extension. // The following properties are required for a Visa Corporate Purchasing Card: TSYSLevel3.CardType = tctVisa; TSYSLevel3.LocalTax = "EXEMPT"; TSYSLevel3.NationalTax = "0"; TSYSLevel3.PurchaseOrder = "purchOrdNum"; TSYSLevel3.MerchantTaxId = "merchantTaxId"; // Merchant VAT Registration Number TSYSLevel3.CustomerTaxId = "customerTaxId"; // Customer VAT Registration Number TSYSLevel3.CommodityCode = "fake"; TSYSLevel3.DiscountAmount = "0"; TSYSLevel3.FreightAmount = "0"; TSYSLevel3.DutyAmount = "0"; TSYSLevel3.DestinationZip = "27709"; TSYSLevel3.ShipFromZip = "27709"; TSYSLevel3.DestinationCountry = "840"; TSYSLevel3.TaxInvoiceNumber = "VATInvoiceRefNo"; TSYSLevel3.OrderDate = "060526"; TSYSLevel3.FreightTaxAmount = "0"; TSYSLevel3.FreightTaxRate = "0"; // Begin adding line items: TSYSLevel3.LineItems.Add(new TSYSLineItem()); TSYSLevel3.LineItems[0].CommodityCode = "fake"; TSYSLevel3.LineItems[0].Description = "hardware"; TSYSLevel3.LineItems[0].ProductCode = "productCode123"; TSYSLevel3.LineItems[0].Quantity = 1; TSYSLevel3.LineItems[0].Units = ""; TSYSLevel3.LineItems[0].UnitCost = "33"; TSYSLevel3.LineItems[0].TaxAmount = "0"; TSYSLevel3.LineItems[0].TaxRate = "0"; TSYSLevel3.LineItems[0].DiscountAmount = "0"; TSYSLevel3.LineItems[0].Total = "33"; TSYSLevel3.LineItems.Add(new TSYSLineItem()); TSYSLevel3.LineItems[1].CommodityCode = "fake"; TSYSLevel3.LineItems[1].Description = "hardware"; TSYSLevel3.LineItems[1].ProductCode = "productCode124"; TSYSLevel3.LineItems[1].Quantity = 1; TSYSLevel3.LineItems[1].Units = ""; TSYSLevel3.LineItems[1].UnitCost = "20"; TSYSLevel3.LineItems[1].TaxAmount = "0"; TSYSLevel3.LineItems[1].TaxRate = "0"; TSYSLevel3.LineItems[1].DiscountAmount = "0"; TSYSLevel3.LineItems[1].Total = "20"; // Finally, add the Level3 addendum to the same index in the settlement. TSYSSettle.DetailRecords[0].AddendumAggregate = TSYSLevel3.GetAddendum();

Note that you may mix corporate and non-corporate card transactions in the same settlement. It is not necessary that all DetailAggregates have a corresponding AddendumAggregate.

DetailAggregate
String
Default Value: ""

Set this field with xml aggregates of the transactions you wish to settle.

To settle previously authorized transactions, this field must be set with the xml aggregate returned from the TSYSRetail, or TSYSECommerce class's GetDetailAggregate method. For instance:

TSYSSettle.DetailRecords.Add(new TSYSRecordType(TSYSRetail.GetDetailAggregate()));

On occasion, you may need to modify these aggregates before sending them to settlement. For instance, if you're running a restaurant you may need to add a gratuity to the charge. If you're accepting installment payments, you will need to add the installment info. To accomplish this, you may use the TSYSDetailRecord class.

For example, to add a gratuity to a charge:

DetailRecord.ParseAggregate(TSYSRetail.GetDetailAggregate()) DetailRecord.Gratuity = "500" DetailRecord.SettlementAmount = DetailRecord.AuthorizedAmount + DetailRecord.Gratuity TSYSSettle.DetailAggregate[0] = DetailRecord.GetDetailAggregate()

To settle a Passenger Transport transaction authorized with the sitPassengerTransport IndustryType, you must use the TSYSDetailRecord class to add the number of this passenger and the total count of all passengers in the authorization code. For instance, if the authorization transaction included "Three passengers", and this is the first passenger, then the passenger number will be 1, and the passenger count 3. An example is included below:

TSYSRetail.IndustryType = sitPassengerTransport TSYSRetail.Authorize() DetailRecord.ParseAggregate TSYSRetail.GetDetailAggregate() DetailRecord.PassengerCount = 3 DetailRecord.PassengerNumber = 1 DetailRecord.Config("RestrictedTicketIndicator=True") DetailRecord.Config("TicketNumber=8382152100395") DetailRecord.Config("PassengerName=John Smith") DetailRecord.Config("DepartureDate=072117") DetailRecord.Config("Origin=JFK") DetailRecord.Config("Leg1=Carrier=DL;ServiceClass=C;StopOver=X;Destination=LAX") TSYSSettle1.IndustryType = sitPassengerTransport TSYSSettle1.Config("TravelAgencyCode=12345678") 'if ticket was issued by a travel agency TSYSSettle1.Config("TravelAgencyName=Travel and Tours") 'if ticket was issued by a travel agency TSYSSettle1.DetailAggregate[5] = DetailRecord.GetDetailAggregate()

TSYSSettleResponse Type

Contains the response to a batch settlement.

Remarks

This type contains the results of a batch settlement made with the TSYSSettle class. The fields contained by this type are listed below.

Fields

Code
String (read-only)
Default Value: ""

Indicates the status of the batch transmission.

This field contains the two character response code returned by the host indicating the status of the Batch Settlement attempt. The following table provides a summary of the response returned by the TSYS host:


GB	Good Batch.
QD	Duplicate Batch.
RB	Rejected Batch.

NetDeposit
String (read-only)
Default Value: ""

Total of purchases minus credits and voids.

This field contains the net deposit generated by the terminal. It should equal the Batch.NetDeposit field, which is computed by the class. The net deposit total is generated by adding the settlement amounts of all detail transaction records and subtracting credit amounts from it. This field is represented as an absolute value and cannot be negative.

Number
int (read-only)
Default Value: 0

Batch number that belongs to this response.

This field should be compared to the BatchNumber in order to match a response with a given Batch Settlement. If running in synchronous mode, this field should always be identical to BatchNumber.

RecordCount
int (read-only)
Default Value: 0

Number of records received by the server in this batch.

This field contains the total number of records received by the host -- including Header, Parameter, Detail, and Trailer records. In the case of a Code of "GB" (Good Batch), the value returned should match the value in the Batch.RecordCount field. In the case of a Code of "RB" (Rejected Batch), this field will reflect the total number of records received until the point of failure. RecordCount + 1 will reveal the sequential number of the transaction record responsible for causing a rejected batch condition, and should be identical to the Error.SequenceNumber field in this case.

Text
String (read-only)
Default Value: ""

Contents of this field are dependent upon the Code.

This nine character field will contain the text "_ACCEPTED" when a settlement batch has been successfully received by the host. However, the Point of Sale (POS) device should examine only the Code to determine the status of a particular Batch Settlement.

TransmissionDate
String (read-only)
Default Value: ""

Date that the batch was settled.

This field is reserved, pending the future upgrade to a higher protocol version.

Constructors

public TSYSSettleResponse();

Config Settings (Tsyssettle Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

TSYSSettle Config Settings

AmexAggregatorName: Contains the name of the Payment Service Provider/Aggregator or Facilitator participating in Amex OptBlue program.

This configuration setting is used for Amex OptBlue participators to determine the name of the Payment Service Provider, Aggragator or Facilitator. You need to set this field for transactions originating from an Aggregator, Payment Service Provider or Facilitator. The maximum length of this field is 12-characters and it must not contain spaces.

CombineRecords: Whether settlement records are being concatenated into a single settlement block.

Default value of this configuration setting is True meaning that settlement records will be combined together to optimize message size and expedite the overall settlement process by minimizing the total number of settlement packets to be transmitted. Setting this to False will send each record as a separate settlement packet during the batch settlement process.

DeviceCode: A 1-character value used to identify the device and type of the merchant submitting the settlement batch.

This configuration setting contains a 1-character value used to identify the device and type of the merchant submitting the settlement batch. The table below provides a summary of currently defined values. The default value for this setting is "Q".


0	Unknown or unsure.
B	Automated Teller Machine (ATM).
C	Personal Computer (PC)
D	Dial terminal
E	Electronic Cash Register (ECR)
G	Mobile Payment Acceptance.
H	TSYS Hosted Payment.
I	In-store processor
J	Multi Payment Acceptance.
M	Mainframe
P	POS-Port
Q	Third-party developer
R	POS-Port
S	POS Partner
T	Counter Payment Acceptance.
W	Web Payment Acceptance.
X	EMV Mode Contact and/or Contactless terminal (Must be used on all EMV mode chip card transactions).
Z	Suppress PS2000/Merit fields

GenKey: A randomly generated string of alphanumeric characters identifying the terminal.

This field is used to specify retrieve or specify a GenKey value for a terminal. This field will be populated after a successful call to ActivateTerminal is made. The Genkey must be stored in the POS device, must be sent with every request to the TSYS Acquiring Solutions host after authentication (by setting this field), and will be checked against the terminal hierarchy. A GenKey value is required when processing transactions using Voltage Encryption or Tokenization.

HeartlandDeviceId: Specifies a device ID to uniquely identify each terminal (card data entry device).

The specified value must be 4 characters or less. Note that this value is required to comply with MasterCard's Authorization Data Accuracy Initiative.

HeartlandEncryptionMode: Specifies the encryption mode to use in Heartland transactions.

This field allows you to specify the Heartland E3 encryption mode used when processing Heartland transactions. The available values are (descriptions describe the data that will be encrypted):


0	No Encryption (default)
1	Merchant ID and Card Data (reserved for future use)
2	Merchant ID, Card Data, and Card Security Code (reserved for future use)
3	Card Data Only

Note you will also need to set Processor to 1 (Heartland) and HeartlandKeyBlock if you wish to process Heartland E3 transactions.

HeartlandKeyBlock: Specifies the key block used to encrypt the data.

This field allows you to specify the key block that was used to encrypt the data specified by HeartlandEncryptionMode. This value will be obtained from an E3 magnetic stripe reader and is used by Heartland to decrypt the encrypted data.

LocationNumber: Provides additional information on the location of the merchant.

This field contains a five character value providing additional information on the location of the merchant. Unless otherwise specified by the merchant's bank or processor, this field should be defaulted to "00001".

This is a Parameter Property, and only needs to be set once for a single Batch Settlement transaction.

Port: The port to which transactions are posted.

This is port that this class connects to on the server. The default value for TSYS is 5003 for the live server, and 5004 for the test server. The default live server values for Heartland is 22341 for Authorization and 22342 for Settlement. The Heartland test server values are 12341 for Authorization and 12342 for Settlement.

Processor: Specifies the Processor you are connecting to.

This field allows you to specify the processor that you are connecting to (thus allowing the class to correctly generate the request and parse the response). The available values are:


0	TSYS (default)
1	Heartland

Note that when set, this property will set the Server and Port to the default values for the specified processor. Additionally, this config must be set prior to setting Card to ensure the card data is formatted correctly.

Server: The server to which transactions are posted.

This is name of the server to which all transactions are posted. Do not use an IP address, use the actual name, as a server's IP address may change. The default (Live) TSYS server is "ssl2.vitalps.net", but you may use "ssltest.tsysacquiring.net" for testing. The default (Live) Heartland server is "txns.secureexchange.net", but you may use "test.txns.secureexchange.net" for testing. Note that there are several BankIds and Numbers that will always run in test mode regardless of whether you are using the live server. See the included demos for examples.

TravelAgencyCode: Contains the Travel Agency IATA Code if the ticket was issued by a travel agency.

You do not need to set this field if the merchant is not a travel agency. The default value of this field is space-filled.

TravelAgencyName: Contains the Travel Agency Name if the ticket was issued by a travel agency.

You do not need to set this field if the merchant is not a travel agency. The default value of this field is space-filled.

UseHTTPPOST: Tells the component whether or not to use HTTP POST when transmitting the Batch for Settlement.

Default value of this configuration setting is False meaning that settlement records will be sent using Socket connection. When True, the component will submit the whole batch at once using POST. You must also set Server to the correct end-point for POST transmission.

Note that the maximum batch size that can be transmitted via POST is 2MB.

TCPClient Config Settings

CloseStreamAfterTransfer: If true, the component will close the upload or download stream after the transfer.

This setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. In order to keep streams open after the transfer of data, set this to False. the default value is True.

ConnectionTimeout: Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect: Tells the class whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost: Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallListener: If true, the component binds to a SOCKS firewall as a server (TCPClient only).

This entry is for TCPClient only and does not work for other components that descend from TCPClient.

If this entry is set, the class acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.

RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.

The connection to the firewall is made by calling the Connect method.

FirewallPassword: Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class throws an exception.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort: The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType: Determines the type of firewall to connect through.

The appropriate values are as follows:


0	No firewall (default setting).
1	Connect through a tunneling proxy. FirewallPort is set to 80.
2	Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3	Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10	Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser: A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class throws an exception.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime: The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger: When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime: Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost: The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

LocalPort: The port in the local host where the class binds.

This must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength: The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate: The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList: A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive: Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay: Whether or not to delay when sending packets.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

UseIPv6: Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:


0	IPv4 Only
1	IPv6 Only
2	IPv6 with IPv4 fallback

UseNTLMv2: Whether to use NTLM V2.

When authenticating with NTLM, this setting specifies whether NTLM V2 is used. By default this value is False and NTLM V1 will be used. Set this to True to use NTLM V2.

SSL Config Settings

LogSSLPackets: Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if SSLProvider is set to Platform.

ReuseSSLSession: Determines if the SSL session is reused.

If set to true, the class will reuse the context if and only if the following criteria are met:

The target host name is the same.
The system cache entry has not expired (default timeout is 10 hours).
The application process that calls the function is the same.
The logon session is the same.
The instance of the class is the same.

SSLCACerts: A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL: Whether to check the Certificate Revocation List for the server certificate.

This setting specifies whether the class will check the Certificate Revocation List specified by the server certificate. If set to 1 or 2, the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class throws an exception.

When set to 0 (default) the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCheckOCSP: Whether to use OCSP to check the status of the server certificate.

This setting specifies whether the class will use OCSP to check the validity of the server certificate. If set to 1 or 2, the class will first obtain the OCSP URL from the server certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class throws an exception.

When set to 0 (default) the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCipherStrength: The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLContextProtocol: The protocol used when getting an SSLContext instance.

Possible values are SSL, SSLv2, SSLv3, TLS and TLSv1. Use it only in case your security provider does not support TLS. This is the parameter "protocol" inside the SSLContext.getInstance(protocol) call.

SSLEnabledCipherSuites: The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Note: This value must be set after SSLProvider is set.

Example values: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA"); obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA; SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA"); Possible values when SSLProvider is set to latform include:

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:

TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols: Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:


TLS1.3	12288 (Hex 3000)
TLS1.2	3072 (Hex C00) (Default)
TLS1.1	768 (Hex 300) (Default)
TLS1	192 (Hex C0) (Default)
SSL3	48 (Hex 30) [Platform Only]
SSL2	12 (Hex 0C) [Platform Only]

SSLEnabledProtocols - TLS 1.3 Notes

By default when TLS 1.3 is enabled the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.

In editions which are designed to run on Windows SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is only supported on Windows 11 / Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider) please be aware of the following notes:

The platform provider is only available on Windows 11 / Windows Server 2022 and up.
SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

SSLEnabledProtocols: SSL2 and SSL3 Notes:

SSL 2.0 and 3.0 are not supported by the class when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.

SSLEnableRenegotiation: Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.

This setting is only applicable when SSLProvider is set to Internal.

SSLIncludeCertChain: Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When SSLProvider is set to Internal this value is automatically set to true. This is needed for proper validation when using the internal provider.

SSLKeyLogFile: The location of a file where per-session secrets are written for debugging purposes.

This setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.

Note: This setting is only applicable when SSLProvider is set to Internal.

SSLNegotiatedCipher: Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength: Returns the negotiated cipher suite strength.

Returns the strength of the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g.TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite: Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange: Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength: Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedVersion: Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLServerCACerts: A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

-----END CERTIFICATE-----

SSLTrustManagerFactoryAlgorithm: The algorithm to be used to create a TrustManager through TrustManagerFactory.

Possible values include SunX509. This is the parameter "algorithm" inside the TrustManagerFactory.getInstance(algorithm) call.

TLS12SignatureAlgorithms: Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the class throws an exception.

The format of this value is a comma separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups: The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1" (default)

TLS13KeyShareGroups: The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

"ecdhe_x25519" (default)
"ecdhe_x448"
"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1"
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096"
"ffdhe_6144"
"ffdhe_8192"

TLS13SignatureAlgorithms: The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

"ed25519" (default)
"ed448" (default)
"ecdsa_secp256r1_sha256" (default)
"ecdsa_secp384r1_sha384" (default)
"ecdsa_secp521r1_sha512" (default)
"rsa_pkcs1_sha256" (default)
"rsa_pkcs1_sha384" (default)
"rsa_pkcs1_sha512" (default)
"rsa_pss_sha256" (default)
"rsa_pss_sha384" (default)
"rsa_pss_sha512" (default)

The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This setting is only applicable when SSLEnabledProtocols includes TLS 1.3.

TLS13SupportedGroups: The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

"ecdhe_x25519" (default)
"ecdhe_x448" (default)
"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1" (default)
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096" (default)
"ffdhe_6144" (default)
"ffdhe_8192" (default)

Socket Config Settings

AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

FirewallData: Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

InBufferSize: The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize: The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo: Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable: Whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The class will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the class does not attempt to process external events.

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

Product: The product the license is for.
Product Key: The key the license was generated from.
License Source: Where the license was found (e.g., RuntimeLicense, License File).
License Type: The type of license installed (e.g., Royalty Free, Single Server).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitive: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseDaemonThreads: Whether threads created by the class are daemon threads.

If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value is True.

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.

This setting is set to false by default on all platforms.
