The FDMSRegister component is a tool used to Register and Activate a merchant account with the Datawire VXN. This allows you to send transactions through the Datawire system to the First Data Merchant Services (FDMS) processor. This component is also used to find the appropriate URLs to which authorizations and settlements will be posted.

Syntax

TibcFDMSRegister

Remarks

The FDMSRegister component is a tool used to Register and Activate a merchant account with the Datawire VXN. This component communicates with the Datawire VXN transaction transport network, and allows you to set up your account so that credit card transactions made with the FDMSECommerce, FDMSRetail, and FDMSSettle components will pass through Datawire and ultimately reach the First Data Merchant Services (FDMS) transaction processor. Before you can charge a single credit card, you must Register and Activate your FDMS account, and then run a ServiceDiscovery to find acceptable URLs, which you will ultimately use to send credit card authorizations.

The first thing you must do is Register your merchant account. First Data Merchant Services will provide you with a MerchantNumber and a MerchantTerminalNumber, which are required for registering with Datawire. If you are registering on the Rapid Connect platform you must also set the GroupId configuration setting. In addition, you will need to set the TransactionNumber with a unique value (the TransactionNumber should be incremented for each transaction you send to the Datawire VXN). The example below also sets the URL to point to the Datawire test server.

FDMSRegister.MerchantNumber = "000000999990" FDMSRegister.MerchantTerminalNumber = "555555" //FDMSRegister.Config("GroupId=FDMS_Assigned_GroupId"); //Rapid Connect Only FDMSRegister.TransactionNumber = "0000001V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do" FDMSRegister.Register()

If the registration was successful, the DatawireStatus will contain "OK", and the DatawireId will contain the new Id which you must save and send with every subsequent transaction. The PrimaryDiscoveryURL and SecondaryDiscoveryURL properties will also be filled after a successful authorization. These URLs should be saved for later, and used to perform ServiceDiscovery.

After registering, you must immediately Activate the merchant. If you wait too long, your registration will time out, and you will have to contact Datawire to have them reset your account so that you may register again. When activating the merchant, the same properties are required as for the Register method, with the addition of the DatawireId property. Since the call to Register filled the DatawireId property with the correct value, all we need to do now is:

FDMSRegister.TransactionNumber = "0000002V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate()

After registering and activating the account, you may now move on to Service Discovery. The Register method will return both a PrimaryDiscoveryURL and a SecondaryDiscoveryURL. Use these URLs with the ServiceDiscovery method to retrieve a list of valid transaction URLs. For instance:

FDMSRegister.ServiceDiscovery("https://staging1.datawire.net/sd")

After a successful ServiceDiscovery the DatawireStatus will be "OK". The discovered URLs will be listed in the ServiceProviders array property. At this time, you should Ping each of these URLs and sort them in order of fastest to slowest response time. You will use the URL with the fastest response time to authorize transactions with FDMSRetail or FDMSECommerce. If the first URL stops responding, you should remove the URL and switch to the next URL in the list. The following example shows how to ping each of the ServiceProviders (you must save and sort the results yourself).

For i = 0 To FDMSRegister.ServiceProvidersCount - 1 FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]) Debug.Print(FDMSRegister.ServiceProviders[i] & " = " & FDMSRegister.PingResponseTime) Next

If your list of servers becomes empty, perform ServiceDiscovery and the subsequent steps to re-populate the list of available servers.

You may now use the DatawireId and the Service Provider URLs retrieved by this component to submit transactions using the FDMSECommerce, FDMSRetail, and FDMSSettle components.

Remarks

This is the type of certificate store for this certificate.

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

SSLCertSubject Property (FDMSRegister Component)

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

Syntax

property SSLCertSubject: String read get_SSLCertSubject write set_SSLCertSubject;

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 as follows:

If a field value contains a comma, it must be quoted.

SSLProvider Property (FDMSRegister Component)

This specifies the SSL/TLS implementation to use.

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 (FDMSRegister Component)

This is the certificate (PEM/Base64 encoded).

Syntax

property SSLServerCertEncoded: String read get_SSLServerCertEncoded;
property SSLServerCertEncodedB: TBytes read get_SSLServerCertEncodedB;

Default Value

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

Timeout Property (FDMSRegister 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).

TransactionNumber Property (FDMSRegister 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 (FDMSRegister Component)

Location of the Datawire server to which transactions are sent.

Syntax

property URL: String read get_URL write set_URL;

Default Value

'https://support.datawire.net/production_expresso/SRS.do'

Remarks

This URL is used by the Register and Activate methods to provision the merchant. The following URLs are available for use:

For the Rapid Connect platform, URL will be populated after a successful ServiceDiscovery request.

Activate Method (FDMSRegister Component)

Activates a merchant account on the Datawire VXN.

Syntax

procedure Activate();

Remarks

After you have successfully registered, you will still not be able to send transactions using the Datawire VXN until you activate your account. For the security reasons, a merchant is required to activate within a limited time period after receiving a successful registration response. Otherwise, the Datawire VXN will deactivate the account and you will need to restart the registration process again.

North, Nashville, and Omaha:

For example:

FDMSRegister.MerchantNumber = "000000999990" FDMSRegister.MerchantTerminalNumber = "555555" FDMSRegister.TransactionNumber = "0000001V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do" FDMSRegister.Register() FDMSRegister.TransactionNumber = "0000002V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate() FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL) For i = 0 To FDMSRegister.ServiceProvidersCount - 1 FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]) Debug.Print(FDMSRegister.ServiceProviders[i] & " = " & FDMSRegister.PingResponseTime) Next

Rapid Connect:

For example:

FDMSRegister.MerchantNumber = "000000999990" FDMSRegister.MerchantTerminalNumber = "555555" FDMSRegister.Config("GroupId=10001") FDMSRegister.TransactionNumber = "0000001VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.ServiceDiscovery("https://prod.dw.us.fdcnet.biz/sd/srsxml.rc") FDMSRegister.ApplicationId = "RAPIDCONNECTSRS" FDMSRegister.TransactionNumber = "0000002VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Register() FDMSRegister.TransactionNumber = "0000003VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate()

Config Method (FDMSRegister 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.

Interrupt Method (FDMSRegister Component)

Interrupts the current action.

Syntax

procedure Interrupt();

Remarks

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

Ping Method (FDMSRegister Component)

Used to find the fastest service provider to use to send credit card transactions.

Syntax

procedure Ping(url: String);

Remarks

The Ping request is used to determine which one of the ServiceProviders URLs is the most efficient to use for transaction transport. The Ping request verifies that the ServiceProviders URLs are reachable and provides the average transaction time cost for each URL, returned in the PingResponseTime property. You should select the fastest ServiceProviders URL to be the active URL that you will use to process all transactions. You should maintain a list of the other ServiceProviders URLs in a queue from fastest to slowest, in the event that the fastest URL becomes unavailable.

A Ping should be sent for each of the ServiceProviders URLs after every 100 authorizations, to ensure that you're still using the fastest URL. A Ping should be run on the ServiceProviders URLs any time the application is first started.

For example:

FDMSRegister.MerchantNumber = "000000999990" FDMSRegister.MerchantTerminalNumber = "555555" FDMSRegister.TransactionNumber = "0000001V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do" FDMSRegister.Register() FDMSRegister.TransactionNumber = "0000002V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate() FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL) For i = 0 To FDMSRegister.ServiceProvidersCount - 1 FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]) Debug.Print(FDMSRegister.ServiceProviders[i] & " = " & FDMSRegister.PingResponseTime) Next

Note: This functionaly does not apply to Rapid Connect implementations.

Register Method (FDMSRegister Component)

Registers a merchant account on the Datawire VXN.

Syntax

procedure Register();

Remarks

For the North, Nashville, and Omaha platforms: FDMS will supply you with a MerchantNumber, MerchantTerminalNumber, and Datawire will supply the URL to use to register your merchant. After setting the above properties, call the Register method. The Register method will send the registration request to Datawire, and will continue to poll the Datawire servers until a response is received. This may take several seconds, or even several minutes.

When the registration is complete, the registration response returns the merchant's DatawireId, and the PrimaryDiscoveryURL and SecondaryDiscoveryURL needed to perform ServiceDiscovery. Once received, these parameters must be saved permanently so that they can be reloaded and configured when necessary and are never lost due to power outages.

For example:

FDMSRegister.MerchantNumber = "000000999990" FDMSRegister.MerchantTerminalNumber = "555555" FDMSRegister.TransactionNumber = "0000001V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do" FDMSRegister.Register() FDMSRegister.TransactionNumber = "0000002V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate() FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL) For i = 0 To FDMSRegister.ServiceProvidersCount - 1 FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]) Debug.Print(FDMSRegister.ServiceProviders[i] & " = " & FDMSRegister.PingResponseTime) Next

For the Rapid Connect platform: ServiceDiscovery will need to be performed first. After a successful ServiceDiscovery call, URL will be populated with the URL required to provision your merchant account. Once TransactionNumber and ApplicationId are set, Register can be called. The Register method will send the registration request to Datawire, and will continue to poll the Datawire servers until a response is received. This may take several seconds, or even several minutes.

When the registration is complete, the registration response returns the merchant's DatawireId, and the PrimaryDiscoveryURL and SecondaryDiscoveryURL needed to process transactions. Once received, these parameters must be saved permanently so that they can be reloaded and configured when necessary and are never lost due to power outages.

For example:

FDMSRegister.MerchantNumber = "000000999990" FDMSRegister.MerchantTerminalNumber = "555555" FDMSRegister.Config("GroupId=10001") FDMSRegister.TransactionNumber = "0000001VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.ServiceDiscovery("https://prod.dw.us.fdcnet.biz/sd/srsxml.rc") FDMSRegister.ApplicationId = "RAPIDCONNECTSRS" FDMSRegister.TransactionNumber = "0000002VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Register() FDMSRegister.TransactionNumber = "0000003VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate()

Reset Method (FDMSRegister Component)

Clears all properties to their default values.

Syntax

procedure Reset();

Remarks

This method clears all properties to their default values.

ServiceDiscovery Method (FDMSRegister Component)

Retrieves transaction URLs from Datawire.

Syntax

procedure ServiceDiscovery(url: String);

Remarks

Service Discovery is the means by which you retrieve the actual transaction URLs, used for making credit card authorizations and sending batch settlements.

For the North, Nashville, and Omaha platforms: The response to a successful call to the Register method will return a PrimaryDiscoveryURL and SecondaryDiscoveryURL. After the account has been activated, call the ServiceDiscovery method with either of these URLs as the URL parameter. A successful ServiceDiscovery will provide a list of Service Provider URL's necessary to transport transactions from the application through the Datawire VXN to the FDMS payment processor and back. This list of URL's returned will be stored in the ServiceProviders array property. You should Ping each of these URLs to determine which one has the shortest PingResponseTime, and use that URL for subsequent credit card transactions (note that you should re-Ping each of the URLs received in the ServiceProviders array every 100 transactions, and when first initializing your software).

For example:

FDMSRegister.MerchantNumber = "000000999990" FDMSRegister.MerchantTerminalNumber = "555555" FDMSRegister.TransactionNumber = "0000001V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do" FDMSRegister.Register() FDMSRegister.TransactionNumber = "0000002V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate() FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL) For i = 0 To FDMSRegister.ServiceProvidersCount - 1 FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]) Debug.Print(FDMSRegister.ServiceProviders[i] & " = " & FDMSRegister.PingResponseTime) Next

For the Rapid Connect platform: ServiceDiscovery will be the first step in provisioning a merchant. FDMS will supply you with a MerchantNumber, MerchantTerminalNumber, and GroupId. After setting these properties, ServiceDiscovery should be called. The default URL, when URL parameter is set to "" (empty string), is "https://prod.dw.us.fdcnet.biz/sd/srsxml.rc". A successful ServiceDiscovery will provide the URL, accessible via URL, necessary to provision a merchant account.

For example:

FDMSRegister.MerchantNumber = "000000999990" FDMSRegister.MerchantTerminalNumber = "555555" FDMSRegister.Config("GroupId=10001") FDMSRegister.TransactionNumber = "0000001VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.ServiceDiscovery("https://prod.dw.us.fdcnet.biz/sd/srsxml.rc") FDMSRegister.ApplicationId = "RAPIDCONNECTSRS" FDMSRegister.TransactionNumber = "0000002VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Register() FDMSRegister.TransactionNumber = "0000003VRC1234" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate()

Connected Event (FDMSRegister Component)

This event is fired immediately after a connection completes (or fails).

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.

DataPacketIn Event (FDMSRegister Component)

Fired when receiving a data packet from the transaction server.

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 (FDMSRegister 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 (FDMSRegister 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 (FDMSRegister 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 (FDMSRegister 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 (FDMSRegister 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 (FDMSRegister 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.

Proxy Type

The proxy the component will connect to.

Remarks

When connecting through a proxy, this type is used to specify different properties of the proxy, such as the Server and the AuthScheme.
