FDMSReversal Class

Properties   Methods   Events   Config Settings   Errors  

The FDMSREVERSAL class is used to reverse a transaction that was previously authorized using the FDMSRETAIL , FDMSECOMMERCE , or FDMSHEALTHCARE class. This immediately releases the funds in the cardholder's open-to-buy that were blocked by the original authorization.

Syntax

FDMSReversal

Remarks

Unlike the Timeout Reversals used in the FDMSDebit and FDMSBenefit classs, a credit card reversal is used to void a transaction and return funds to the customer. Often this is used in a split-tender situation, where a customer uses a prepaid Visa or MasterCard (or health care FSA card) to make a purchase which is partially authorized for less than the transaction amount. Partially authorized transactions will have an ResponseApprovalCode that beings with "AL" instead of "AP". If the customer does not have an additional source of funds to make up the difference, the authorization must be reversed and the funds immediately returned to the customer's card. To do this, set the AuthorizedAmount to the Response.AuthorizedAmount from the original transaction, and set the SettlementAmount to "0". This is called a full reversal (in this case, of a partially authorized transaction), and the detail record for the original transaction should be discarded - it must not be settled at the end of the day.

Alternatively, a merchant may need to settle a transaction amount for less than was originally authorized. In this case, set the AuthorizedAmount to the original TransactionAmount, and set the SettlementAmount to the new amount you wish to settle for. After a successful reversal, use the FDMSDetailRecord class to update the SettlementAmount of the detail record for the original transaction with the new amount. This is called a partial reversal. You may also submit a full reversal by setting the SettlementAmount to "0". In that case, all of the funds are returned to the customer and the detail record for the original transaction should be discarded.

Note that partial authorizations must be fully reversed. You cannot partially reverse a partial authorization. Normally authorized transactions can be either partially or fully reversed. A normal authorization has a ResponseApprovalCode that begins with "AP" (APproved). A partial authorization has a ResponseApprovalCode that begins with "AL" (Approved for a Lesser amount).

Upon a successful reversal, the ResponseApprovalCode property will contain either "AP888888" or "AP868686" indicating the reversal was accepted. This code does not indicate the original transaction was found and reversed, merely that the reversal was received and properly formatted. First Data does not actually check whether the original transaction occurred or not. If the transaction was declined ResponseApprovalCode will contain one of the response messages listed in the table below:

Response MessageMeaning
CALL CARD CENTER System problem.
DECLINED Decline the transaction.
EXPIRED CARD Card is expired.
HOLD - CALL CTR Problem with card.
INV ACCT NUM Invalid card number or prefix.
INV CREDIT PLAN Private label message only.
INV EXP DATE Invalid expiration date.
INV MER ID Merchant is not set up on Host file.
INV TERM ID Terminal is not set up on Host file.
PLEASE RETRY System time-out or other generic system error.
REFERRAL Referral.
REFERRAL INV TR2 Referral - Invalid Track II Data.
REFERRAL INV TR1 Referral - Invalid Track I Data.
SERV NOT ALLOWED Merchant is not entitled to this card type.
SYS REJECT Transaction was rejected by the system due to "batch in progress indicators" being turned on.
INV AMT Invalid amount.
INV TRAN Transaction not permitted
REV REJECTED Reversal was rejected.
TRAN NOT ALLOWED Transaction not allowed.
The following example starts with a simple $3 manually-keyed retail transaction: FDMSRetail1.TransactionNumber = 3; FDMSRetail1.TransactionAmount = "300"; FDMSRetail1.Card.Number = "4111111111111111"; FDMSRetail1.Card.ExpMonth = 12; FDMSRetail1.Card.ExpYear = 13; FDMSRetail1.Card.EntryDataSource = edsManuallyEntered; FDMSRetail1.Authorize(); The above authorization was successful, but for some reason it needs to be voided. You could simply not settle the transaction, and that would clear the block on the cardholder's funds in a few days. However, a reversal allows you to clear that block immediately. To start with, we set the FDMSReversal class with the same merchant setup and basic transaction info used in the original authorization. FDMSReversal1.MerchantNumber = FDMSRetail1.MerchantNumber; FDMSReversal1.MerchantTerminalNumber = FDMSRetail1.MerchantTerminalNumber; FDMSReversal1.DatawireId = FDMSRetail1.DatawireId; FDMSReversal1.URL = FDMSRetail1.URL; FDMSReversal1.Card.Number = FDMSRetail1.Card.Number; FDMSReversal1.Card.ExpMonth = FDMSRetail1.Card.ExpMonth; FDMSReversal1.Card.ExpYear = FDMSRetail1.Card.ExpYear; FDMSReversal1.Card.EntryDataSource = FDMSRetail1.Card.EntryDataSource; Next, we need to specify the exact transaction we wish to reverse. The properties below are required for First Data to identify and reconcile the reversal. Note that if the original transaction was authorized for an amount less than the original TransactionAmount, AuthorizedAmount should be set with the ResponseAuthorizedAmount from the original transaction, instead of the TransactionAmount which was requested. FDMSReversal1.ApprovalCode = FDMSRetail1.Response.ApprovalCode; FDMSReversal1.TransactionId = FDMSRetail1.Response.TransactionId; FDMSReversal1.AuthorizedAmount = FDMSRetail1.TransactionAmount; FDMSReversal1.ReturnedACI = FDMSRetail1.Response.ReturnedACI; FDMSReversal1.ValidationCode = FDMSRetail1.Response.ValidationCode; All that is left is to set the new settlement amount and submit the transaction. To completely reverse the transaction and return all funds to the customer, set the SettlementAmount to zero ("0"). To return a portion of the funds to the customer set the SettlementAmount property with the result of the original authorized amount minus the amount to be unblocked on the customer's card. For instance, this $3 transaction has $2 reversed, for a new settlement amount of $1. FDMSReversal1.TransactionNumber = 4; FDMSReversal1.SettlementAmount = "100"; FDMSReversal1.Reverse(); If the reversal is successful the ResponseApprovalCode will contain either "AP868686" or "AP888888", indicating the reversal was accepted.

Note that partially authorized transactions cannot be partially reversed, they must be fully reversed. For instance, say a customer uses a prepaid visa card to buy $100 worth of merchandise, but his card only has a $50 balance. If the customer does not have an additional form of tender, (cash, check, credit, etc), the $50 that was partially authorized must be reversed and returned to the card. First Data does not support any scenario where a partially authorized transaction may be reversed for less than the full amount.

To reiterate, when a transaction is fully reversed, it must be removed from the batch settlement entirely. A partially reversed transaction must update the SettlementAmount of the original detail record, using the FDMSDetailRecord class. Reversal transactions themselves may not be settled, even if the ResponseCaptureFlag is True.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister class. (You may update your list of service provider URLs with the FDMSRegister class's ServiceDiscovery method).

Remarks

This property should be set with the Response.ApprovalCode from the transaction you wish to reverse.

Data Type

String

AuthorizedAmount Property (FDMSReversal Class)

Authorized Amount from the original response.

Syntax

ANSI (Cross Platform)
char* GetAuthorizedAmount();
int SetAuthorizedAmount(const char* lpszAuthorizedAmount); Unicode (Windows) LPWSTR GetAuthorizedAmount();
INT SetAuthorizedAmount(LPCWSTR lpszAuthorizedAmount);
char* dpaymentssdk_fdmsreversal_getauthorizedamount(void* lpObj);
int dpaymentssdk_fdmsreversal_setauthorizedamount(void* lpObj, const char* lpszAuthorizedAmount);
QString GetAuthorizedAmount();
int SetAuthorizedAmount(QString qsAuthorizedAmount);

Default Value

""

Remarks

This property should be set with the actual authorized amount from the transaction you wish to reverse. If the transaction was partially authorized (Response.AuthorizedAmount was present in the response, and different than the original TransactionAmount), then this property should be set to the AuthorizedAmount returned in the original response. Otherwise it should be set to the original TransactionAmount.

If the original transaction was partially authorized, you cannot do a partial reversal. Partially authorized transactions must be fully reversed (meaning SettlementAmount must be set to "0").

In the case of reversing a transaction containing incremental authorizations, this property should be set to the first (initial) authorization amount. The TotalAuthorizedAmount config should then be set to the total authorization amount (first authorization plus all incremental authorizations).

int dpaymentssdk_fdmsreversal_setcardisencrypted(void* lpObj, int bCardIsEncrypted);
bool GetCardIsEncrypted();
int SetCardIsEncrypted(bool bCardIsEncrypted);

Default Value

FALSE

Remarks

Determines whether data set to the CardNumber or CardMagneticStripe fields is validated.

By default, when the CardNumber or CardMagneticStripe fields are set, the value will be validated and normalized. For instance, "4444-33332222 1111" will be normalized as "4444333322221111" and CardMagneticStripe data will be parsed for the track specified by CardEntryDataSource. However, any other non-numerical data entered will cause an exception to be thrown. It may be useful in some gateways to send other data in the CardNumber or CardMagneticStripe fields, and this can be accomplished by setting IsEncrypted to true. However, please note that in doing so automatic calculation of the CardType may be affected, and the card number will not be verified.

This property is not available at design time.

It is not recommended that the Point of Sale (POS) system attempt to interpret the meaning of this value. Instead, the POS system should extract whatever value is returned in this field and submit it in the batch settlement. The POS system should not interpret any relationship between this field and the presence of data in either the ResponseTransactionId or ResponseValidationCode fields.

The following is a list of all returned ACI values. Please note that many of these return values result from features not available in any of the currently supported Industry Types.

SettlementAmount Property (FDMSReversal Class)

New settlement amount after the reversal.

Syntax

ANSI (Cross Platform)
char* GetSettlementAmount();
int SetSettlementAmount(const char* lpszSettlementAmount); Unicode (Windows) LPWSTR GetSettlementAmount();
INT SetSettlementAmount(LPCWSTR lpszSettlementAmount);
char* dpaymentssdk_fdmsreversal_getsettlementamount(void* lpObj);
int dpaymentssdk_fdmsreversal_setsettlementamount(void* lpObj, const char* lpszSettlementAmount);
QString GetSettlementAmount();
int SetSettlementAmount(QString qsSettlementAmount);

Default Value

""

Remarks

To send a full reversal, the new SettlementAmount should be set to "0". The entire transaction will then be reversed, and the original transaction should not be settled with the FDMSSettle class. If you wish to reverse only part of the transaction (known as a "partial reversal"), simply set the SettlementAmount to the new total, minus reversal amount. For instance, if you have a $25 transaction and you wish to reverse $10 because one item was not in stock, set the AuthorizedAmount to "2500" and the SettlementAmount to "1500", and then call Reverse to do a partial reversal.

Note that partial reversals may not be performed on partially authorized transactions. If the ApprovalCode starts with "AL" and the Response.AuthorizedAmount from the original transaction was less than the original TransactionAmount, a full reversal must be performed with the SettlementAmount set to "0".

Remarks

This is the name of the certificate store for the client certificate.

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject property for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

int GetSSLCertStoreType();
int SetSSLCertStoreType(int iSSLCertStoreType);

Default Value

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.
6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.

18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.
22 (cstBCFKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SSLCertStore and set SSLCertStorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Data Type

Integer

SSLCertSubject Property (FDMSReversal Class)

This is the subject of the certificate used for client authentication.

Syntax

ANSI (Cross Platform)
char* GetSSLCertSubject();
int SetSSLCertSubject(const char* lpszSSLCertSubject); Unicode (Windows) LPWSTR GetSSLCertSubject();
INT SetSSLCertSubject(LPCWSTR lpszSSLCertSubject);

QString GetSSLCertSubject();
int SetSSLCertSubject(QString qsSSLCertSubject);

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization

int dpaymentssdk_fdmsreversal_getsslprovider(void* lpObj);
int dpaymentssdk_fdmsreversal_setsslprovider(void* lpObj, int iSSLProvider);
int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

Default Value

0

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, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

Data Type

Integer

SSLServerCertEncoded Property (FDMSReversal Class)

This is the certificate (PEM/base64 encoded).

Syntax

ANSI (Cross Platform)
int GetSSLServerCertEncoded(char* &lpSSLServerCertEncoded, int &lenSSLServerCertEncoded);

Unicode (Windows)
INT GetSSLServerCertEncoded(LPSTR &lpSSLServerCertEncoded, INT &lenSSLServerCertEncoded);
int dpaymentssdk_fdmsreversal_getsslservercertencoded(void* lpObj, char** lpSSLServerCertEncoded, int* lenSSLServerCertEncoded);
QByteArray GetSSLServerCertEncoded();

Default Value

""

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

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

This property is read-only and not available at design time.

Data Type

Binary String

Timeout Property (FDMSReversal Class)

A timeout for the class.

Syntax

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout); Unicode (Windows) INT GetTimeout();
INT SetTimeout(INT iTimeout);
int dpaymentssdk_fdmsreversal_gettimeout(void* lpObj);
int dpaymentssdk_fdmsreversal_settimeout(void* lpObj, int iTimeout);
int GetTimeout();
int SetTimeout(int iTimeout);

Default Value

30

Remarks

If Timeout is set to a positive value, and an operation cannot be completed immediately, the class will return with an error after Timeout seconds.

The default value for Timeout is 30 (seconds).

Data Type

Integer

TransactionId Property (FDMSReversal Class)

Transaction Id from the original response.

Syntax

ANSI (Cross Platform)
char* GetTransactionId();
int SetTransactionId(const char* lpszTransactionId); Unicode (Windows) LPWSTR GetTransactionId();
INT SetTransactionId(LPCWSTR lpszTransactionId);
char* dpaymentssdk_fdmsreversal_gettransactionid(void* lpObj);
int dpaymentssdk_fdmsreversal_settransactionid(void* lpObj, const char* lpszTransactionId);
QString GetTransactionId();
int SetTransactionId(QString qsTransactionId);

Default Value

""

Remarks

This property should be set with the Response.TransactionId from the transaction you wish to reverse.

Data Type

String

TransactionNumber Property (FDMSReversal Class)

Uniquely identifies the transaction.

Syntax

ANSI (Cross Platform)
char* GetTransactionNumber();
int SetTransactionNumber(const char* lpszTransactionNumber); Unicode (Windows) LPWSTR GetTransactionNumber();
INT SetTransactionNumber(LPCWSTR lpszTransactionNumber);
char* dpaymentssdk_fdmsreversal_gettransactionnumber(void* lpObj);
int dpaymentssdk_fdmsreversal_settransactionnumber(void* lpObj, const char* lpszTransactionNumber);
QString GetTransactionNumber();
int SetTransactionNumber(QString qsTransactionNumber);

Default Value

""

Remarks

The TransactionNumber (otherwise known as the Client Reference Number, or ClientRef) uniquely identifies the packet sent by the application to the Datawire system. This parameter stores some unique token of information, and is used to match the response to the initial request sent. For example, the client application could use a static counter that is increased with the each executed request.

For all classs except FDMSGiftCard the maximum length of this property is 14 alphanumeric characters.

The FDMS recommended format is "tttttttVnnnnrrr" where ttttttt is a 7 digit transaction id, V is a constant, and nnn is a 3 digit version number and rrr is a 3 digit revision number. The 6 digit version number is typically static but unique for an application (Example: Version 2.5 = tttttttV002500).

For the Rapid Connect platform, the 6 character version number should be your Project/TPPID value. The entire TransactionNumber must be unique within a 24 hour time period.

The FDMSGiftCard also passes this value to the FDMS Closed Loop Gift Card system as a transaction id, and therefore the following restrictions are enforced: The maximum length is 7 characters. If the first character is an 'X', the remaining characters must be in the range '0' through 'F', indicating a hexadecimal number. Otherwise the FDMS Closed Loop Gift Card system only allows digits in this property.

Data Type

String

URL Property (FDMSReversal Class)

Location of the Datawire server to which transactions are sent.

Syntax

ANSI (Cross Platform)
char* GetURL();
int SetURL(const char* lpszURL); Unicode (Windows) LPWSTR GetURL();
INT SetURL(LPCWSTR lpszURL);
char* dpaymentssdk_fdmsreversal_geturl(void* lpObj);
int dpaymentssdk_fdmsreversal_seturl(void* lpObj, const char* lpszURL);
QString GetURL();
int SetURL(QString qsURL);

Default Value

"https://staging1.datawire.net/sd/"

Remarks

This is the URL to which all authorization and settlement transactions are sent. This URL is acquired by using the FDMSRegister class. Once you Register and Activate the merchant using the FDMSRegister class, you may then do a Service Discovery. After sending a Service Discovery transaction, the Datawire system will return a list of transaction URLs. The URL from this list with the shortest round-trip transit time from a ping is the URL you should use here.

Note: By default, this property is populated with the Datawire Staging (test) server, and is not the correct URL to use in a production environment. In a production environment, this URL is supplied by the FDMSRegister class.

Data Type

String

ValidationCode Property (FDMSReversal Class)

Validation Code from the original response.

Syntax

ANSI (Cross Platform)
char* GetValidationCode();
int SetValidationCode(const char* lpszValidationCode); Unicode (Windows) LPWSTR GetValidationCode();

Data Type

String

Config Method (FDMSReversal Class)

Sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
char* dpaymentssdk_fdmsreversal_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Interrupt Method (FDMSReversal Class)

Interrupts the current action.

Syntax

ANSI (Cross Platform)
int Interrupt();

Unicode (Windows)
INT Interrupt();
int dpaymentssdk_fdmsreversal_interrupt(void* lpObj);
int Interrupt();

Remarks

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

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Reset Method (FDMSReversal Class)

Clears all properties to their default values.

Syntax

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();
int dpaymentssdk_fdmsreversal_reset(void* lpObj);
int Reset();

Remarks

This method clears all properties to their default values.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Reverse Method (FDMSReversal Class)

Reverses a credit card transaction.

Syntax

ANSI (Cross Platform)
int Reverse();

Unicode (Windows)
INT Reverse();
int dpaymentssdk_fdmsreversal_reverse(void* lpObj);
int Reverse();

Remarks

Unlike the Timeout Reversals used in the FDMSDebit and FDMSBenefit classs, a credit card reversal is used to void a transaction and return funds to the customer. Often this is used in a split-tender situation, where a customer uses a prepaid Visa or MasterCard (or health care FSA card) to make a purchase which is partially authorized for less than the transaction amount. Partially authorized transactions will have an ResponseApprovalCode that beings with "AL" instead of "AP". If the customer does not have an additional source of funds to make up the difference, the authorization must be reversed and the funds immediately returned to the customer's card. To do this, set the AuthorizedAmount to the Response.AuthorizedAmount from the original transaction, and set the SettlementAmount to "0". This is called a full reversal (in this case, of a partially authorized transaction), and the detail record for the original transaction should be discarded - it must not be settled at the end of the day.

Alternatively, a merchant may need to settle a transaction amount for less than was originally authorized. In this case, set the AuthorizedAmount to the original TransactionAmount, and set the SettlementAmount to the new amount you wish to settle for. After a successful reversal, use the FDMSDetailRecord class to update the SettlementAmount of the detail record for the original transaction with the new amount. This is called a partial reversal. You may also submit a full reversal by setting the SettlementAmount to "0". In that case, all of the funds are returned to the customer and the detail record for the original transaction should be discarded.

Note that partial authorizations must be fully reversed. You cannot partially reverse a partial authorization. Normally authorized transactions can be either partially or fully reversed. A normal authorization has a ResponseApprovalCode that begins with "AP" (APproved). A partial authorization has a ResponseApprovalCode that begins with "AL" (Approved for a Lesser amount).

Upon a successful reversal, the ResponseApprovalCode property will contain either "AP888888" or "AP868686" indicating the reversal was accepted. This code does not indicate the original transaction was found and reversed, merely that the reversal was received and properly formatted. First Data does not actually check whether the original transaction occurred or not. If the transaction was declined ResponseApprovalCode will contain one of the response messages listed in the table below:

Response MessageMeaning
CALL CARD CENTER System problem.
DECLINED Decline the transaction.
EXPIRED CARD Card is expired.
HOLD - CALL CTR Problem with card.
INV ACCT NUM Invalid card number or prefix.
INV CREDIT PLAN Private label message only.
INV EXP DATE Invalid expiration date.
INV MER ID Merchant is not set up on Host file.
INV TERM ID Terminal is not set up on Host file.
PLEASE RETRY System time-out or other generic system error.
REFERRAL Referral.
REFERRAL INV TR2 Referral - Invalid Track II Data.
REFERRAL INV TR1 Referral - Invalid Track I Data.
SERV NOT ALLOWED Merchant is not entitled to this card type.
SYS REJECT Transaction was rejected by the system due to "batch in progress indicators" being turned on.
INV AMT Invalid amount.
INV TRAN Transaction not permitted
REV REJECTED Reversal was rejected.
TRAN NOT ALLOWED Transaction not allowed.
The following example starts with a simple $3 manually-keyed retail transaction: FDMSRetail1.TransactionNumber = 3; FDMSRetail1.TransactionAmount = "300"; FDMSRetail1.Card.Number = "4111111111111111"; FDMSRetail1.Card.ExpMonth = 12; FDMSRetail1.Card.ExpYear = 13; FDMSRetail1.Card.EntryDataSource = edsManuallyEntered; FDMSRetail1.Authorize(); The above authorization was successful, but for some reason it needs to be voided. You could simply not settle the transaction, and that would clear the block on the cardholder's funds in a few days. However, a reversal allows you to clear that block immediately. To start with, we set the FDMSReversal class with the same merchant setup and basic transaction info used in the original authorization. FDMSReversal1.MerchantNumber = FDMSRetail1.MerchantNumber; FDMSReversal1.MerchantTerminalNumber = FDMSRetail1.MerchantTerminalNumber; FDMSReversal1.DatawireId = FDMSRetail1.DatawireId; FDMSReversal1.URL = FDMSRetail1.URL; FDMSReversal1.Card.Number = FDMSRetail1.Card.Number; FDMSReversal1.Card.ExpMonth = FDMSRetail1.Card.ExpMonth; FDMSReversal1.Card.ExpYear = FDMSRetail1.Card.ExpYear; FDMSReversal1.Card.EntryDataSource = FDMSRetail1.Card.EntryDataSource; Next, we need to specify the exact transaction we wish to reverse. The properties below are required for First Data to identify and reconcile the reversal. Note that if the original transaction was authorized for an amount less than the original TransactionAmount, AuthorizedAmount should be set with the ResponseAuthorizedAmount from the original transaction, instead of the TransactionAmount which was requested. FDMSReversal1.ApprovalCode = FDMSRetail1.Response.ApprovalCode; FDMSReversal1.TransactionId = FDMSRetail1.Response.TransactionId; FDMSReversal1.AuthorizedAmount = FDMSRetail1.TransactionAmount; FDMSReversal1.ReturnedACI = FDMSRetail1.Response.ReturnedACI; FDMSReversal1.ValidationCode = FDMSRetail1.Response.ValidationCode; All that is left is to set the new settlement amount and submit the transaction. To completely reverse the transaction and return all funds to the customer, set the SettlementAmount to zero ("0"). To return a portion of the funds to the customer set the SettlementAmount property with the result of the original authorized amount minus the amount to be unblocked on the customer's card. For instance, this $3 transaction has $2 reversed, for a new settlement amount of $1. FDMSReversal1.TransactionNumber = 4; FDMSReversal1.SettlementAmount = "100"; FDMSReversal1.Reverse(); If the reversal is successful the ResponseApprovalCode will contain either "AP868686" or "AP888888", indicating the reversal was accepted.

Note that partially authorized transactions cannot be partially reversed, they must be fully reversed. For instance, say a customer uses a prepaid visa card to buy $100 worth of merchandise, but his card only has a $50 balance. If the customer does not have an additional form of tender, (cash, check, credit, etc), the $50 that was partially authorized must be reversed and returned to the card. First Data does not support any scenario where a partially authorized transaction may be reversed for less than the full amount.

To reiterate, when a transaction is fully reversed, it must be removed from the batch settlement entirely. A partially reversed transaction must update the SettlementAmount of the original detail record, using the FDMSDetailRecord class. Reversal transactions themselves may not be settled, even if the ResponseCaptureFlag is True.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister class. (You may update your list of service provider URLs with the FDMSRegister class's ServiceDiscovery method).

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SSLServerAuthentication Event (FDMSReversal Class)

Fired after the server presents its certificate to the client.

Syntax

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(FDMSReversalSSLServerAuthenticationEventParams *e);
typedef struct {
const char *CertEncoded; int lenCertEncoded;
const char *CertSubject;
const char *CertIssuer;

int Accept; int reserved; } FDMSReversalSSLServerAuthenticationEventParams;
Unicode (Windows) virtual INT FireSSLServerAuthentication(FDMSReversalSSLServerAuthenticationEventParams *e);
typedef struct {
LPCSTR CertEncoded; INT lenCertEncoded;
LPCWSTR CertSubject;
LPCWSTR CertIssuer;
LPCWSTR Status;
BOOL Accept; INT reserved; } FDMSReversalSSLServerAuthenticationEventParams;
#define EID_FDMSREVERSAL_SSLSERVERAUTHENTICATION 6

virtual INT DPAYMENTSSDK_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);
class FDMSReversalSSLServerAuthenticationEventParams {
public:

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SSLServerAuthentication(FDMSReversalSSLServerAuthenticationEventParams *e);
// Or, subclass FDMSReversal and override this emitter function. virtual int FireSSLServerAuthentication(FDMSReversalSSLServerAuthenticationEventParams *e) {...}

Remarks

This event is where the client can decide whether to continue with the connection process or not. 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 to continue or not.

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 (FDMSReversal Class)

Shows the progress of the secure connection.

Syntax

ANSI (Cross Platform)
virtual int FireSSLStatus(FDMSReversalSSLStatusEventParams *e);

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

Config Settings (FDMSReversal 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.

FDMSReversal Config Settings

AVSResult:   Contains the Address Verification System result code of the transaction to be reversed.

This field should be set with the Response.AVSResult from the transaction you wish to reverse.

ClientTimeout:   Indicates timeout client application will wait for response.

This setting indicates the interval of time, in seconds, a client will wait for the response for any given request. Normally this value is set to a value 5 seconds less than the Timeout value to allow for a response to be received from Datawire. It may be changed independently by setting this configuration setting AFTER setting the Timeout property. Note that too small a value will cause Datawire to reject a transaction immediately.

ECI:   Electronic Commerce Indicator.

The Electronic Commerce Indicator is automatically set by the class dependent upon the DirectMarketingType and IndustryType. This configuration setting should be set to the value used within the Electronic Commerce transaction that you are reversing.

IsCOF:   Set this to process a Credential On File transaction.

To process a Credential On File transaction you need to set this IsCOF flag to True. Default value is False.

IsOnlineRefund:   Indicates whether you are reversing an Online Refund transaction.

Set this config to True when you are reversing an Online Refund transaction. Note: Currently only Amex does NOT support Online Refund.

PINCapability:   The PIN Capability of the terminal.

This setting allows you to specify the PIN Capability of the terminal. The available values are:

Value Description
0 Unknown
1 Terminal can accept PIN.
2 (default) Terminal cannot accept PIN.
8 Pad is down.
9 PIN verified by terminal device.
RawRequest:   Returns the request sent to the server for debugging purposes.

After an operation this setting may be queried to return the request as it was sent to the server. This is useful for debugging purposes.

RawResponse:   Returns the response received from the server for debugging purposes.

After an operation this setting may be queried to return the response as it was received from the server. This is useful for debugging purposes.

TotalAuthorizedAmount:   The total amount authorized including all incremental authorizations.

This field is used to specify the total amount authorized for the transaction you wish to reverse, including incremental authorizations. If reversing a single authorization, without additional incremental authorizations, you can simply set AuthorizedAmount and the component will set this field for you in the request. However when reversing a transaction with incremental authorizations, this field must be set to the total amount authorized (first authorization plus all additional incremental authorizations). The AuthorizedAmount property should be set to the first authorized amount (from the initial authorization transaction).

TCPClient Config Settings

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.

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 fails with an error.

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:

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

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.

KeepAliveRetryCount:   The number of keep-alive packets to be sent before the remotehost is considered disconnected.

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 number of times that the keep-alive packets will be sent before the remote host is considered disconnected. The system default if this value is not specified here is 9.

Note: This configuration setting is only available in the Unix platform. It is not supported in masOS or FreeBSD.

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

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.

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile:   Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

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

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList:   A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData:   The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

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.

SSLCACertFilePaths:   The paths to CA certificate files on Unix/Linux.

This setting specifies the paths on disk to CA certificate files on Unix/Linux.

The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.

The default value is:

/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem

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-----

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

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.

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.

Example values when SSLProvider is set to Platform: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform 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:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

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.

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.

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]");

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown Certificate Authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

This functionality is currently not available when the provider is OpenSSL.

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

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

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 fails with an error.

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

  • "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.

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.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Tells the class 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 setting to true tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.

Trappable Errors (FDMSReversal Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
