FDMSReversal Control

Properties   Methods   Events   Config Settings   Errors  

The FDMSREVERSAL control is used to reverse a transaction that was previously authorized using the FDMSRETAIL , FDMSECOMMERCE , or FDMSHEALTHCARE control. 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 controls, 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 control 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:

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 control. 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 control. (You may update your list of service provider URLs with the FDMSRegister control's ServiceDiscovery method).

Identifies the merchant application to the Datawire System.

Syntax

fdmsreversalcontrol.ApplicationId[=string]

Default Value

"NSOFTDIRECTPXML"

Remarks

The Application ID includes the Merchant's application name and version number. This property is used to identify the merchant application within the Datawire system, and may be validated along with the MerchantTerminalNumber and DatawireId as connection credentials.

The default value of this property is assigned to the 4D Payments FDMS Integrator, but you may be required to have a new ApplicationId assigned for the software you create with this control.

Data Type

String

ApprovalCode Property (FDMSReversal Control)

Approval code of the transaction to be reversed.

Syntax

fdmsreversalcontrol.ApprovalCode[=string]

Default Value

""

Remarks

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

Data Type

String

AuthorizedAmount Property (FDMSReversal Control)

Authorized Amount from the original response.

Syntax

fdmsreversalcontrol.AuthorizedAmount[=string]

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).

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 control. 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".

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.

To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertEncodedB.

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

Data Type

Binary String

Timeout Property (FDMSReversal Control)

A timeout for the control.

Syntax

fdmsreversalcontrol.Timeout[=integer]

Data Type

Integer

TransactionId Property (FDMSReversal Control)

Transaction Id from the original response.

Syntax

fdmsreversalcontrol.TransactionId[=string]

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 Control)

Uniquely identifies the transaction.

Syntax

fdmsreversalcontrol.TransactionNumber[=string]

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 controls 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 Control)

Location of the Datawire server to which transactions are sent.

Syntax

fdmsreversalcontrol.URL[=string]

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 control. Once you Register and Activate the merchant using the FDMSRegister control, 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 control.

Data Type

String

ValidationCode Property (FDMSReversal Control)

Validation Code from the original response.

Syntax

fdmsreversalcontrol.ValidationCode[=string]

Default Value

""

Remarks

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

Data Type

String

Config Method (FDMSReversal Control)

Sets or retrieves a configuration setting.

Syntax

fdmsreversalcontrol.Config ConfigurationString

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, 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 (FDMSReversal Control)

Interrupts the current action.

Syntax

fdmsreversalcontrol.Interrupt 

Remarks

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

Reset Method (FDMSReversal Control)

Clears all properties to their default values.

Syntax

fdmsreversalcontrol.Reset 

Remarks

This method clears all properties to their default values.

Reverse Method (FDMSReversal Control)

Reverses a credit card transaction.

Syntax

fdmsreversalcontrol.Reverse 

Remarks

Unlike the Timeout Reversals used in the FDMSDebit and FDMSBenefit controls, 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 control 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:

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 control. 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 control. (You may update your list of service provider URLs with the FDMSRegister control's ServiceDiscovery method).

Connected Event (FDMSReversal Control)

Fired immediately after a connection completes (or fails).

Syntax

Sub fdmsreversalcontrol_Connected(StatusCode As Integer, Description As String)

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 Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

DataPacketIn Event (FDMSReversal Control)

Fired when receiving a data packet from the transaction server.

Syntax

Sub fdmsreversalcontrol_DataPacketIn(DataPacket As String)

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 control.

DataPacketOut Event (FDMSReversal Control)

Fired when sending a data packet to the transaction server.

Syntax

Sub fdmsreversalcontrol_DataPacketOut(DataPacket As String)

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 control.

Disconnected Event (FDMSReversal Control)

Fired when a connection is closed.

Syntax

Sub fdmsreversalcontrol_Disconnected(StatusCode As Integer, Description As String)

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 the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

Error Event (FDMSReversal Control)

Fired when information is available about errors during data delivery.

Syntax

Sub fdmsreversalcontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter 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 (FDMSReversal Control)

Fired after the server presents its certificate to the client.

Syntax

Sub fdmsreversalcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

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 (FDMSReversal Control)

Fired when secure connection progress messages are available.

Syntax

Sub fdmsreversalcontrol_SSLStatus(Message As String)

Remarks

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

Status Event (FDMSReversal Control)

Shows the progress of the FDMS/Datawire connection.

Syntax

Sub fdmsreversalcontrol_Status(Message As String)

Remarks

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