The FDMSRetail component is an advanced tool used to authorize credit cards in a Retail environment, where the customer is purchasing products or services in person. This component makes authorizing these types of transactions very easy. Supported Industry Types include retail stores, restaurants, and grocery or food stores.

Syntax

TibcFDMSRetail

Remarks

This component connects to the First Data Merchant Services (FDMS) processor, by way of the Datawire VXN transaction transport network. Transactions originating with these components go through Datawire, to the FDMS processor where the transaction is authorized. The result is then returned back through Datawire and received by the component. This component can be integrated into web pages or stand-alone Point Of Sale applications. Because all SSL communications are handled inside the component, any application or web page can be deployed without the need for expensive dedicated SSL servers.

The FDMSRetail component makes authorizing Card-Present transactions (where the customer's card is swiped through a card reader) very easy by adding an additional layer of abstraction between the programmer and the protocol. There is no need to deal with raw sockets, TLS/SSL handshakes, or data packet formatting. The steps to setting up the component and authorizing a transaction are outlined below:

First, you must register and activate your account with Datawire. Datawire will provide you with a MerchantNumber and MerchantTerminalNumber, but you'll need to use the FDMSRegister component to activate the merchant and receive a DatawireId. Once you acquire the DatawireId and receive your transaction URLs through Service Discovery, you may begin to authorize transactions.

To authorize a credit card, set the MerchantNumber and MerchantTerminalNumber with the values supplied by FDMS and Datawire, and the DatawireId with the value retrieved by the FDMSRegister component after activating your merchant account. Set the URL property with one of the URLs you retrieved during Service Discovery.

FDMSRetail.MerchantNumber = "000000999990" 'Supplied by FDMS/Datawire FDMSRetail.MerchantTerminalNumber = "555555" 'Supplied by FDMS/Datawire FDMSRetail.DatawireId = "0000B47FFFFFFFFFFFFF" 'Retrieved with the FDMSRegister component. FDMSSettle.URL = "https://staging1.datawire.net/sd/"; 'Retrieved with the FDMSRegister component.

Next, set properties that contain details about the transaction. The TransactionNumber should be incremented for every transaction you authorize. The TransactionAmount must be set, and it should contain the amount to be charged, with an implied decimal point (ie: $1.00 is "100"). The IndustryType will indicate whether the transaction is made for a Retail store, a restaurant, or a grocery store.

FDMSRetail.TransactionNumber = 1 FDMSRetail.TransactionAmount = "100" FDMSRetail.IndustryType = itRetail

Now, set the credit card properties. If available, you should use Track1 data. Some cards may have a corrupt or missing track1, and for these cards you may use track2 data. If the card is not readable, you may also manually enter the card number and expiration date. The following example shows a transaction sent with track1 data.

FDMSRetail.CardMagneticStripe = "%B4444333322221111^SMITH/JOHN J ^031210100000033301000000008000000?" FDMSRetail.CardEntryDataSource = edsTrack1

Finally, submit the transaction by calling the Authorize method.

When the component receives a response, the result of the authorization will be available in several Response properties. The DatawireStatus and DatawireReturnCode indicate whether any errors occurred while passing the transaction through the Datawire VXN system. These two properties alone do not indicate a successful transaction, they only tell whether or not there were any problems transporting the authorization request and response through the Datawire system. If the transaction was successfully authorized by FDMS, then the CaptureFlag will be True, and the ApprovalCode will contain an approval code that beings with "AP". (or "AL" for components that support partially-approved/split-tender transactions). The remaining properties provide additional information about the transaction.

Once an authorization request is approved, the money in the customer's account is blocked and tagged for the merchant. This transaction must go through the Batch Settlement process in order for the blocked money to be transferred to the merchant account. This is done by passing the XML aggregate returned from the GetDetailAggregate method to the FDMSSettle component. Usually, a Batch Settlement of all authorized transactions is done at the end of each business day.

Syntax

property SSLProvider: TibcTSSLProviders read get_SSLProvider write set_SSLProvider;

TibcTSSLProviders = (
  sslpAutomatic,
  sslpPlatform,
  sslpInternal
);

Default Value

sslpAutomatic

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 component 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:

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

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

SSLServerCertEncoded Property (FDMSRetail Component)

Timeout Property (FDMSRetail Component)

A timeout for the component.

Syntax

property Timeout: Integer read get_Timeout write set_Timeout;

Default Value

30

Remarks

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

The default value for Timeout is 30 (seconds).

TPPID Property (FDMSRetail Component)

Third Party Processor Identifier assigned by FDMS.

Syntax

property TPPID: String read get_TPPID write set_TPPID;

Default Value

'V4D001'

Remarks

The Third Party Processor Identifier (TPPID. Also sometimes referred to as a "Vendor Id") is assigned by FDMS to each third party who is processing transactions. Each merchant will receive his own TPPID from FDMS. If there are multiple third parties involved in the transaction flow, additional TPPID's are required. These may be added by setting the TPPID property with a comma-delimited list. The first entry should always be the servicer that sends the transaction to FDMS. Each subsequent servicer should be identified where they are in the chain. There can be a maximum of three entries in this list.

The default value for 4D Payments, Inc. on the North and Nashville platforms is "V4D001".

Note: This value will be reset to the default value when FDMSPlatform is set.

A VisaIdentifier is also required for Visa transactions.

TransactionAmount Property (FDMSRetail Component)

Purchase amount to be authorized.

Syntax

property TransactionAmount: String read get_TransactionAmount write set_TransactionAmount;

Default Value

''

Remarks

This property contains the transaction amount to be authorized.

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

TransactionNumber Property (FDMSRetail Component)

Uniquely identifies the transaction.

Syntax

property TransactionNumber: String read get_TransactionNumber write set_TransactionNumber;

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 components 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.

URL Property (FDMSRetail Component)

Location of the Datawire server to which transactions are sent.

Syntax

property URL: String read get_URL write set_URL;

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

VisaIdentifier Property (FDMSRetail Component)

Additional merchant identification field used when authorizing Visa transactions.

Syntax

property VisaIdentifier: String read get_VisaIdentifier write set_VisaIdentifier;

Default Value

''

Remarks

In conjunction with Visa regulatory change(s), First Data will require the Agent Identification Service from all Third Party Servicers (TPS) or Merchant Servicers (MS). Each 19-byte Visa Agent Identifier in the chain is composed of the following pieces:

A VisaIdentifier (Agent Identification Service - AUAR) is required for Visa transactions. A VisaIdentifier value is assigned by Visa as part of their Trusted Agent Program (TAP). Therefore it is suggested that you contact your FDMS certification analyst as they should be able to provide you with further information and put you in contact with the required party at Visa. Unfortunately more specific information on this matter cannot be provided as we do not handle live customer data and thus are not required to register in this particular program. However below is some additional information in regards to the requirements of a Visa Identifier.

Any merchant that transmits, processes, or stores cardholder data on server(s) that you own, manage, or operate on behalf of your clients (who are other merchant account holders) must meet the PCI Data Security Standard and follow additional steps to register as a service provider. Applicable services commonly include webhosting, software as a service, or collecting payment on behalf of a client. Any company providing these services must register with Visa's Third Party Agent (TAP) program.

You can register for the Visa Third Party Agent Program at http://usa.visa.com/merchants/risk_management/third-party-registration.html

If you find that you are not required to register with this program you can send the following value for VisaIdentifier: 0B 000000000000

Authorize Method (FDMSRetail Component)

Authorizes a credit card using track1, track2, or manually entered card data.

Syntax

procedure Authorize();

Remarks

This method sends an authorization request through Datawire to the FDMS transaction processor. The EntryDataSource property determines whether Track1, Track2, or manually entered card and expiration date are sent in the request. If the authorization request was successful, the CaptureFlag property will be True, and the ApprovalCode will contain an approval code.

An authorization blocks funds on the customer's credit card, but does not actually transfer funds. In order for funds to be transferred and the transaction completed, you must settle the transaction. To do this, you must pass an XML aggregate containing the results of the transaction to the Settlement component. For example:

FDMSRetail.CardMagneticStripe = "B4444333322221111^SMITH/JOHN M ^031210100000033301000000008000000" FDMSRetail.CardEntryDataSource = edsTrack1 FDMSRetail.Authorize() If (FDMSRetail.ResponseCaptureFlag = True) Then FDMSSettle.DetailRecordCount = 1 FDMSSettle.DetailAggregate[0] = FDMSRetail.GetDetailAggregate() End If Industry regulations do not allow merchants or processors to store track data in any form of persistent storage. Failure to abide by this regulation can result in significant fines and other penalties.

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

AVSAndCVVOnly Method (FDMSRetail Component)

Performs an AVS/CVV only check using the specified Card data.

Syntax

procedure AVSAndCVVOnly();

Remarks

This methods allows you to perform an AVS/CVV only request for verification purposes using the specified Card data. This does not authorize any funds on the card and only performs an AVS and CVV check. The TransactionAmount must be 0 for this transaction.

Note: For Retail transactions the EntryDataSource must be set to a manual entry value for this transaction.

FDMSRetail.CardEntryDataSource = edsManualEntryTrack1Capable FDMSRetail.CardNumber = "4444333322221111" FDMSRetail.CardExpMonth = 9 FDMSRetail.CardExpYear = 2015 FDMSRetail.CardCVVData = "999" FDMSRetail.CustomerAddress = "123 Nowhere Ln" FDMSRetail.CustomerZip = "90210" FDMSRetail.TransactionAmount = "0" FDMSRetail.AVSAndCVVOnly()

BalanceInquiry Method (FDMSRetail Component)

Performs a Balance Inquiry Request using the specified Card data.

Syntax

procedure BalanceInquiry();

Remarks

This methods allows you to perform a Balance Inquiry Request using the specified Card data. The balance amount will be returned via Balance. Note that Balance Inquiries do not place a hold on a cardholder's funds and are not captured.

FDMSRetail.CardMagneticStripe = "B4444333322221111^SMITH/JOHN M ^031210100000033301000000008000000" FDMSRetail.CardEntryDataSource = edsTrack1 FDMSRetail.BalanceInquiry() Industry regulations do not allow merchants or processors to store track data in any form of persistent storage. Failure to abide by this regulation can result in significant fines and other penalties.

Config Method (FDMSRetail Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

GetDetailAggregate Method (FDMSRetail Component)

Returns an aggregate containing details of this transaction, which is then used for settlement.

Syntax

function GetDetailAggregate(): String;

Remarks

This method returns an aggregate containing all of the required data to send a transaction to settlement. This aggregate must be passed to the FDMSSettle component's DetailAggregate array property in order to settle the transaction. If you wish to view or change any part of the aggregate (such as adding a gratuity or additional info for an Installment payment), you may use the FDMSDetailRecord component to do so.

Note: This method may only be called after a successful authorization. If the authorization was not successful (and the CaptureFlag is false) the method raises an exception.

An example of how this method is used is shown below:

FDMSRetail.AuthorizeTrack1() If (FDMSRetail.ResponseCaptureFlag = True) Then FDMSSettle.DetailRecordCount = FDMSSettle.DetailRecordCount + 1 FDMSSettle.DetailRecordsAggregate[FDMSSettle.DetailRecordCount - 1] = FDMSRetail.GetDetailAggregate() End If

Interrupt Method (FDMSRetail Component)

Interrupts the current action.

Syntax

procedure Interrupt();

Remarks

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

Reset Method (FDMSRetail Component)

Clears all properties to their default values.

Syntax

Syntax

type TConnectedEvent = procedure (
  Sender: TObject;
  StatusCode: Integer;
  const Description: String
) of Object;

property OnConnected: TConnectedEvent read FOnConnected write FOnConnected;

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.

Please refer to the Error Codes section for more information.

Syntax

type TDataPacketInEvent = procedure (
  Sender: TObject;
  DataPacket: String;
  DataPacketB: TBytes
) of Object;

property OnDataPacketIn: TDataPacketInEvent read FOnDataPacketIn write FOnDataPacketIn;

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 component.

DataPacketOut Event (FDMSRetail Component)

Fired when sending a data packet to the transaction server.

Syntax

type TDataPacketOutEvent = procedure (
  Sender: TObject;
  DataPacket: String;
  DataPacketB: TBytes
) of Object;

property OnDataPacketOut: TDataPacketOutEvent read FOnDataPacketOut write FOnDataPacketOut;

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 component.

Disconnected Event (FDMSRetail Component)

This event is fired when a connection is closed.

Syntax

type TDisconnectedEvent = procedure (
  Sender: TObject;
  StatusCode: Integer;
  const Description: String
) of Object;

property OnDisconnected: TDisconnectedEvent read FOnDisconnected write FOnDisconnected;

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.

Please refer to the Error Codes section for more information.

Error Event (FDMSRetail Component)

Fired when information is available about errors during data delivery.

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

property OnError: TErrorEvent read FOnError write FOnError;

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

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 (FDMSRetail Component)

Fired after the server presents its certificate to the client.

Syntax

type TSSLServerAuthenticationEvent = procedure (
  Sender: TObject;
  CertEncoded: String;
  CertEncodedB: TBytes;
  const CertSubject: String;
  const CertIssuer: String;
  const Status: String;
  var Accept: Boolean
) of Object;

property OnSSLServerAuthentication: TSSLServerAuthenticationEvent read FOnSSLServerAuthentication write FOnSSLServerAuthentication;

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 (FDMSRetail Component)

Fired when secure connection progress messages are available.

Syntax

type TSSLStatusEvent = procedure (
  Sender: TObject;
  const Message: String
) of Object;

property OnSSLStatus: TSSLStatusEvent read FOnSSLStatus write FOnSSLStatus;

Remarks

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

Status Event (FDMSRetail Component)

Shows the progress of the FDMS/Datawire connection.

Syntax

type TStatusEvent = procedure (
  Sender: TObject;
  const Message: String
) of Object;

property OnStatus: TStatusEvent read FOnStatus write FOnStatus;

Remarks

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

CCCard Type

Contains the customer's credit card information.

Remarks

This type contains the customer's credit card information. If you are processing transactions where the customer and his credit card are physically present, set the MagneticStripe field with the data read from the card reader. You may set either Track1 or Track2 data (but not both). You must also set the EntryDataSource to indicate which track is stored in the MagneticStripe field.

Example: Setting the Fields CCCard card = new CCCard(); card.MagneticStripe = "B4012000033330026^FDMS TEST CARD /VISA^090410054321000000000000000 150 A"; card.EntryDataSource = edsTrack1; Example: Using a Constructor CCCard card = new CCCard("B4012000033330026^FDMS TEST CARD /VISA^090410054321000000000000000 150 A", edsTrack1);

If you are processing a transaction where the credit card is not physically present (eCommerce, mail/order, etc) or if the magstripe on the back of the card cannot be read by the card reader, you must set the Number, ExpMonth, and ExpYear fields, and EntryDataSource must be set to one of the manually entered enumerations.

Example: Setting the Fields CCCard card = new CCCard(); card.Number = "4788250000028291"; card.ExpMonth = 12; card.ExpYear = 2010; card.EntryDataSource = edsManualEntryNoCardReader; Example: Using a Constructor CCCard card = new CCCard("4012000033330026", 04, 2009); Note that the constructor in the previous example automatically sets the EntryDataSource to edsManualEntryNoCardReader. If you wish to set any other value for the EntryDataSource, you must set it yourself before authorizing the transaction.

When authorizing a transaction, the fields used by the component are solely dependant on the value of EntryDataSource. If you set the Number, ExpMonth, and ExpYear fields, but EntryDataSource is set to edsTrack2, the component will look for MagneticStripe data when authorizing the transaction, and will raises an exception because none is present.

Fields

Constructors

constructor Create();

constructor Create(valNumber: String; valExpMonth: Integer; valExpYear: Integer);

constructor Create(valMagneticStripe: String; valEntryDataSource: TibcEntryDataSources);
