The FDMSOmahaBatchMgr module is used to close batches and also handles the sending of all offline transactions to the FDMS Host.

Syntax

DPaymentsSDK.Fdmsomahabatchmgr

Remarks

This component allows for a connection to the FDMS Omaha platform via a VPN or PPP (dial-up) connection. This component can be integrated into web pages or stand-alone Point Of Sale applications.

The FDMSOmahaBatchMgr component makes sending offline transactions and closing batches 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, set the merchant and POS specific properties with setup information acquired from your member bank or processor. For instance: FDMSOmahaBatchMgr.MerchantNumber = "123456789123456" FDMSOmahaBatchMgr.MerchantTerminalID = "XXX01" FDMSOmahaBatchMgr.DeviceId = "DID1" // Optional, Merchant-Assigned

Next, add all the detail records for the transactions you wish to settle in the batch. Note that all the added detail records must be transactions that are processed within the same batch that you wish to close. Below is an example of how to add a detail record to the OmahaBatchMgr component. FDMSOmahaBatchMgr.DetailRecordCount = 1; FDMSOmahaBatchMgr.DetailRecordAggregate[0] = FDMSOmahaRetail.GetDetailAggregate()

The BatchNumber and TransactionNumber should then be set. Note the BatchNumber should be the same value as all the transactions contained within the DetailRecords. The TransactionNumber specified must be 1 greater than the number of Credit Card transactions specified within DetailRecords and less than the last Debit/EBT Card TransactionNumber specified. See TransactionNumber for more specific information. FDMSOmahaBatchMgr.BatchNumber = 1 FDMSOmahaBatchMgr.TransactionNumber = 2

Finally the batch can be closed by calling CloseBatch. When CloseBatch is called, all the off-line transactions (Voids, Revisions, etc.) will be sent to the Host. After all the off-line transactions have been successfully sent, the batch close request will be sent. If the batch was successfully closed, ResponseSuccess will be 'True'. FDMSOmahaBatchMgr.CloseBatch()

Note it is possible that the Host may be out-of-balance with the Total Amount specified (which is calculated by the component based on the information contained within the DetailRecords). If such a case occurs, the Host may request an inquiry to synchronize all transactions (this request is sent after a batch close message is sent by the component). When the component receives this request, it will handle all inquiries and respond accordingly based on the request and information contained within DetailRecords. Once the host is in sync, the Host will send the close batch response and Response will be populated. ResponseSuccess will be true if the batch was successfully closed.

ApplicationId Property (FDMSOmahaBatchMgr Module)

Identifies the merchant application to the Datawire System.

Syntax

• Swift
• Objective-C

public var applicationId: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=applicationId,setter=setApplicationId:) NSString* applicationId;

- (NSString*)applicationId;
- (void)setApplicationId :(NSString*)newApplicationId;

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 class.

Note: This property is only applicable when TransportProtocol is set to '0' (Datawire).

BatchNumber Property (FDMSOmahaBatchMgr Module)

Number identifying the batch (assigned by the POS device).

Syntax

• Swift
• Objective-C

public var batchNumber: Int32 {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=batchNumber,setter=setBatchNumber:) int batchNumber;

- (int)batchNumber;
- (void)setBatchNumber :(int)newBatchNumber;

Default Value

0

Remarks

This property is used to specify the number identifying the batch that the transaction will be processed in.

This is a consecutive numbering system assigned by the POS application that identifies a batch of transactions. The batch number must increment each time a batch is successfully closed. When the batch number reaches 9, it is the responsibility of the application to recycle the batch number to 0. The Host will allow a variety of sequencing of the batch number, but you cannot have the same batch number in consecutive batches. For example: The application can close batch 2 and open the next batch with number 5, but you cannot close batch 2 then re-open batch 2 without a different batch number in between. If you should receive a message of "INV BATCH SEQ", this usually indicates the current batch number is the same as the previous batch number closed or there is a batch still open on the Host and the application is trying to process a transaction with a different batch number. If a batch is left open for more than 45 days, (45 days from the open date, not last activity date), the system will automatically purge the batch and it will not be retrievable.

Valid values: 0-9

ClientRef Property (FDMSOmahaBatchMgr Module)

Uniquely identifies the transaction within the Datawire system.

Syntax

• Swift
• Objective-C

public var clientRef: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=clientRef,setter=setClientRef:) NSString* clientRef;

- (NSString*)clientRef;
- (void)setClientRef :(NSString*)newClientRef;

Default Value

""

Remarks

The ClientRef (Client Reference Number) 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.

The maximum length of this property is 14 alphanumeric characters.

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

The entire TransactionNumber must be unique within a 24 hour time period.

Note: If a value is not specified, the component will generate a value for you. The transaction id will be generated based on the current time (hour of day and minutes) along with the TransactionNumber specified. The version number is hard-coded based on the current library version which is 16.X.X (016XX0).

DatawireId Property (FDMSOmahaBatchMgr Module)

Identifies the merchant to the Datawire System.

Syntax

• Swift
• Objective-C

public var datawireId: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=datawireId,setter=setDatawireId:) NSString* datawireId;

- (NSString*)datawireId;
- (void)setDatawireId :(NSString*)newDatawireId;

Default Value

""

Remarks

The Datawire Id is a unique customer identifier generated by Datawire and returned to the client after successfully registering the merchant (using the FDMSRegister class). This Id (which is sent in all subsequent transactions) allows a transaction, to pass through the Datawire system and be correctly routed to the FDMS Payment processor.

The maximum length for this property is 32 characters.

Note: This property is only applicable when TransportProtocol is set to '0' (Datawire).

DetailRecords Property (FDMSOmahaBatchMgr Module)

Collection of detail records to send in the close batch transaction.

Syntax

• Swift
• Objective-C

public var detailRecords: Array<FDMSOmahaRecordType> {
  get {...}
}

@property (nonatomic,readwrite,assign,getter=detailRecordCount,setter=setDetailRecordCount:) int detailRecordCount;

- (int)detailRecordCount;
- (void)setDetailRecordCount :(int)newDetailRecordCount;

- (NSString*)detailRecordAggregate:(int)detailRecordIndex;
- (void)setDetailRecordAggregate:(int)detailRecordIndex :(NSString*)newDetailRecordAggregate;

Default Value

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

Remarks

Each FDMSOmahaRecordType object in the collection specifies an XML aggregate representing the transaction to be settled. The XML aggregate to be settled is generated from the FDMSOmahaRetail, FDMSOmahaRestaurant, FDMSOmahaECommerce, or FDMSOmahaDetailRecord class.

The following example shows how to add a detail record to the collection. FDMSOmahaEcommerce1.Authorize(); FDMSOmahaBatchMgr1.DetailRecords.Add(new FDMSOmahaRecordType(FDMSOmahaEcommerce1.GetDetailAggregate()));

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

Up to 998 detail records may be settled in the above manner, just by adding a transactions to the DetailRecords property. However, it is recommended that Batch Closes be kept relatively small - around 100 transactions or so - to decrease the number of records that must be present in the event of an error.

DeviceId Property (FDMSOmahaBatchMgr Module)

POS Device Identification.

Syntax

• Swift
• Objective-C

public var deviceId: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=deviceId,setter=setDeviceId:) NSString* deviceId;

- (NSString*)deviceId;
- (void)setDeviceId :(NSString*)newDeviceId;

Default Value

""

Remarks

Merchant-assigned code identifying the device at the merchant's location.

This field is required if there is one MerchantNumber assigned to more than one terminal at a merchant's location.

The maximum length of this property is 4 characters.

LocalHost Property (FDMSOmahaBatchMgr Module)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

• Swift
• Objective-C

public var localHost: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=localHost,setter=setLocalHost:) NSString* localHost;

- (NSString*)localHost;
- (void)setLocalHost :(NSString*)newLocalHost;

Default Value

""

Remarks

The LocalHost property 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 property 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).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

Note: This property is only applicable when TransportProtocol is set to '1' (VPN Connection).

LocalPort Property (FDMSOmahaBatchMgr Module)

The TCP port in the local host where the module binds.

Syntax

• Swift
• Objective-C

public var localPort: Int32 {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=localPort,setter=setLocalPort:) int localPort;

- (int)localPort;
- (void)setLocalPort :(int)newLocalPort;

Default Value

0

Remarks

This property 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 property to 0 (default) enables the system to choose an open port at random. The chosen port will be returned by the LocalPort property after the connection is established.

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

This property is useful when trying to connect to services that require a trusted port in the client side.

Note: This property is only applicable when TransportProtocol is set to '1' (VPN Connection).

MerchantNumber Property (FDMSOmahaBatchMgr Module)

A unique number used to identify the merchant within the FDMS systems.

RemoteHost Property (FDMSOmahaBatchMgr Module)

This property includes the address of the remote host. Domain names are resolved to IP addresses.

Syntax

• Swift
• Objective-C

public var remoteHost: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=remoteHost,setter=setRemoteHost:) NSString* remoteHost;

- (NSString*)remoteHost;
- (void)setRemoteHost :(NSString*)newRemoteHost;

Default Value

""

Remarks

This property specifies the IP address (IP number in dotted internet format) or the domain name of the remote host. It is set before a connection is attempted and cannot be changed once a connection is established.

If this property is set to a domain name, a DNS request is initiated, and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.

If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.

Example. Connecting:

TCPClientControl.RemoteHost = "MyHostNameOrIP" TCPClientControl.RemotePort = 777 TCPClientControl.Connected = true

Note: This property is only applicable when TransportProtocol is set to '1' (VPN Connection).

  set {...}
}

@property (nonatomic,readwrite,assign,getter=SSLCertSubject,setter=setSSLCertSubject:) NSString* SSLCertSubject;

- (NSString*)SSLCertSubject;
- (void)setSSLCertSubject :(NSString*)newSSLCertSubject;

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.

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

If an error occurs when setting this property an error will not be thrown. This property has a related method which will throw an error:

public func setSSLCertSubject(sslCertSubject: String) throws

SSLProvider Property (FDMSOmahaBatchMgr Module)

This specifies the SSL/TLS implementation to use.

Syntax

  case sslpInternal = 2
}

@property (nonatomic,readwrite,assign,getter=SSLProvider,setter=setSSLProvider:) int SSLProvider;

- (int)SSLProvider;
- (void)setSSLProvider :(int)newSSLProvider;

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:

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

When Automatic is selected the platform implementation will be used by default in all cases in the macOS edition.

  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=timeout,setter=setTimeout:) int timeout;

- (int)timeout;
- (void)setTimeout :(int)newTimeout;

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).

TransactionNumber Property (FDMSOmahaBatchMgr Module)

The transaction number for the current transaction.

Syntax

• Swift
• Objective-C

public var transactionNumber: Int32 {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=transactionNumber,setter=setTransactionNumber:) int transactionNumber;

- (int)transactionNumber;
- (void)setTransactionNumber :(int)newTransactionNumber;

Default Value

0

Remarks

This property is used to specify the transaction number for the current transaction. The valid values are 0 - 999. A TransactionNumber of 0 is only used and MUST be used for AuthOnly transactions, thus all other transaction types must have a TransactionNumber of 1 or greater. The maximum value of TransactionNumber is 999 (note: closing a batch requires an item number and thus the actual number of transactions in a batch is 998).

If a transaction is unsuccessful the TransactionNumber should be re-used.

For Credit Card transactions, the TransactionNumber starts at 1 (provided it is not an AuthOnly transaction) and must increment with each successful transaction.

For Debit/EBT Card transactions, the TransactionNumber starts at 999 and must decrement with each successful transaction.

Note TransactionNumbers for Credit Card and Debit/EBT cards *cannot* overlap and must be unique. Additionally, there must be an open TransactionNumber for the close batch transaction. For example, you can have 1-454 for Credit Card transactions and 456-999 for Debit/EBT cards but TransactionNumber 455 must be left available for the close batch transaction.

Item numbers do NOT have to be processed in sequence (i.e. 1, 2, 3, etc.). However, when a batch is closed all transactions up to the TransactionNumber specified to close the batch must be accounted for. For example; if a batch is closed using TransactionNumber 5, transactions 1, 2, 3, and 4 MUST be accounted for. Additionally, if the batch is closed using an TransactionNumber that is not one more than the number of items in the batch, the Host will delete all records over the close TransactionNumber. For example; if a batch is closed using TransactionNumber 5, transaction records 5, 6, 7, etc. will be automatically deleted by the system.

Each transaction that posts to the Host with an TransactionNumber must keep that TransactionNumber until the batch is closed. Note: the Host accepts two or more transactions with the same TransactionNumber, but the last transaction will overwrite any previous transactions. For example, if a Sale is performed for TransactionNumber 1 and then a Credit is performed, only the Credit will post to the cardholder's account (it will be as if the Sale transaction never happened, with the exception of the reserved funds).

This property is not applicable for the ottRevise and ottVoid transaction types. Thus when GetDetailAggregate is called, the returned aggregate will contain the TransactionNumber specified within the original transaction.

Below is a table of the various transaction types and how TransactionNumber should be handled for Credit Card transactions. Note that the below table is only applicable to Credit Card transactions.

Debit/EBT cards are always performed online and thus each successful transaction should have their own unique TransactionNumber that starts at 999 and decrements by 1 for each success transaction performed.

URL Property (FDMSOmahaBatchMgr Module)

Location of the Datawire server to which transactions are sent.

Syntax

• Swift
• Objective-C

public var url: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=URL,setter=setURL:) NSString* URL;

- (NSString*)URL;
- (void)setURL :(NSString*)newURL;

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.

Note: This property is only applicable when TransportProtocol is set to '0' (Datawire).

CloseBatch Method (FDMSOmahaBatchMgr Module)

Sends a Close Batch request.

Syntax

• Swift
• Objective-C

public func closeBatch() throws -> Void

- (void)closeBatch;

Remarks

This method sends a close batch request to the FDMS transaction processor, which initiates the settlement of the transactions contained within the batch.

By default, prior to CloseBatch being called, all the detail aggregates for every transaction within the batch should be added to DetailRecords. These detail records are used by the component to send all offline transactions and compute the total transaction amounts for the batch (which are sent in the close batch request).

When CloseBatch is called, all the offline transactions (Voids, Revisions, etc) contained within DetailRecords will be sent prior to the actual close batch request. After all the offline transactions have been sent, the batch close message is sent. If the Host is out-of-balance with the Total Amount specified (which is calculated by the component based on the information contained within the DetailRecords), the Host may request an inquiry to synchronize all transactions. If such a case occurs, the component will handle all inquiries and respond accordingly based on the request and information contained within DetailRecords. Once the host is in sync, the Host will send the close batch response and Response will be populated. ResponseSuccess will be true if the batch was successfully closed.

Note: TransactionNumber must be one greater than the number of Credit Card transactions and must also be less than the number of Debit/EBT Card transactions within the batch.

Note under specific circumstances, it may be advantageous for you to manually handle batch amounts and polling or revision inquiries (rather then adding all the transaction aggregates to DetailRecords). To do this, you can set the following configuration settings CreditBatchAmount, DebitBatchCount, and DebitBatchAmount. When these configuration settings are set, the component does not compute batch amount totals and thus only the offline transaction aggregates need to be added to DetailRecords. If a revision or specific poll inquiry is requested by the host, rather than the component automatically sending a response based on the DetailRecords, the RevisionInquiry or SpecificPoll events will fire. Within these events, you will be required to set the information requested which will be used to send the inquiry response. OmahaBatchMgr.BatchNumber = 1; OmahaBatchMgr.TransactionNumber = 10; OmahaBatchMgr.CloseBatch();

Config Method (FDMSOmahaBatchMgr Module)

Sets or retrieves a configuration setting.

Syntax

• Swift
• Objective-C

public func config(configurationString: String) throws -> String

- (NSString*)config:(NSString*)configurationString;

Remarks

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

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

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

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

DepositInquiry Method (FDMSOmahaBatchMgr Module)

Sends a Deposit Inquiry request.

Syntax

• Swift
• Objective-C

public func depositInquiry() throws -> Void

- (void)depositInquiry;

Remarks

This method sends a Deposit Inquiry request and allows the merchant to view the last batch closed with the same MerchantNumber and DeviceId from the previous processing day.

Response will contain the details of the deposit inquiry response. OmahaBatchMgr.DepositInquiry();

Interrupt Method (FDMSOmahaBatchMgr Module)

Interrupts the current action.

Syntax

• Swift
• Objective-C

public func interrupt() throws -> Void

- (void)interrupt;

Remarks

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

Reset Method (FDMSOmahaBatchMgr Module)

Clears all properties to their default values.

Syntax

• Swift
• Objective-C

public func reset() throws -> Void

- (void)reset;

Remarks

This method clears all properties to their default values.

Connected Event (FDMSOmahaBatchMgr Module)

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

Syntax

• Swift
• Objective-C

func onConnected(statusCode: Int32, description: String)

- (void)onConnected:(int)statusCode :(NSString*)description;

Remarks

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

If the connection fails, StatusCode has the error code returned by the 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.

Note: This event is not fired when TransportProtocol is set to '1' (VPN Connection).

DataPacketIn Event (FDMSOmahaBatchMgr Module)

Fired when receiving a data packet from the transaction server.

Syntax

• Swift
• Objective-C

func onDataPacketIn(dataPacket: Data)

- (void)onDataPacketIn:(NSData*)dataPacket;

Remarks

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

DataPacketOut Event (FDMSOmahaBatchMgr Module)

Fired when sending a data packet to the transaction server.

Syntax

• Swift
• Objective-C

func onDataPacketOut(dataPacket: Data)

- (void)onDataPacketOut:(NSData*)dataPacket;

Remarks

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

Disconnected Event (FDMSOmahaBatchMgr Module)

This event is fired when a connection is closed.

Syntax

• Swift
• Objective-C

func onDisconnected(statusCode: Int32, description: String)

- (void)onDisconnected:(int)statusCode :(NSString*)description;

Remarks

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

If the connection is broken for any other reason, StatusCode has the error code returned by 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.

Note: This event is not fired when TransportProtocol is set to '1' (VPN Connection).

Error Event (FDMSOmahaBatchMgr Module)

Information about errors during data delivery.

Syntax

• Swift
• Objective-C

func onError(errorCode: Int32, description: String)

- (void)onError:(int)errorCode :(NSString*)description;

Remarks

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

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

RevisionInquiry Event (FDMSOmahaBatchMgr Module)

Fired when a revision inquiry request is received from the host.

Syntax

• Swift
• Objective-C

func onRevisionInquiry(startTransactionNumber: Int32, revisionNumbers: inout String)

- (void)onRevisionInquiry:(int)startTransactionNumber :(NSString**)revisionNumbers;

Remarks

This event fires when a revision inquiry request is received. Note that this is only applicable when manually handling the batch close details (occurs when setting CreditBatchAmount and DebitBatchAmount). Otherwise the component will compute batch details and handle all revision and specific poll inquiries.

StartTransactionNumber is used to identify the transaction number where the revision number list should begin.

RevisionNumbers is a comma-separated list containing the total number of revisions for each transaction. The maximum length of the list is 10 revision numbers or until you reach the last transaction number within the batch (whichever comes first).

For example, you have 12 transactions within the current batch with transaction 3 being voided, 9 being revised once and then voided, and transaction 12 being revised once. (Revisions include all transactions that have been revised or voided). A revision inquiry is requested and RevisionInquiry is fired with a StartTransactionNumber of 1. '1' specifies that we need to start with the first transaction number. Therefore RevisionNumbers should be set to the following list for transactions 1-10: "0,0,1,0,0,0,0,0,2,0". So the '1' in the list represents transaction 3 which was voided. The '2' in the list represents transaction 9 which was revised once and then voided (thus it was revised twice). Once specified, the component will send the revision inquiry response with the numbers specified. Upon a successful response, the host may send back a batch close response or request another revision inquiry. Let's say a second revision inquiry was requested. When RevisionInquiry is fired, TransactionNumber will be 11 (from our current example). Thus RevisionNumbers should be set to: "0,1" for transactions 11 and 12 (12 being the last one in the batch).

Note FDMS does have time constraints on when a response should be sent and received by the host which can be as low as 4 seconds. Therefore the handling and specifying of the RevisionNumbers should occur in a timely manner to ensure that all requests/responses can be processed without the connection being closed.

SpecificPoll Event (FDMSOmahaBatchMgr Module)

Fired when a specific poll request is received from the host.

Syntax

• Swift
• Objective-C

func onSpecificPoll(transactionNumber: Int32, aggregate: inout String)

- (void)onSpecificPoll:(int)transactionNumber :(NSString**)aggregate;

Remarks

This event fires when a specific poll request is received (which occurs when the host is out-of-balance with the Total Amount specified). Note that this is only applicable when manually handling the batch close details (occurs when setting CreditBatchAmount and DebitBatchAmount). Otherwise the component will compute batch details and handle all revision and specific poll inquiries.

TransactionNumber is used to identify the transaction number requested by the host.

Aggregate should be set to the detail aggregate for the specified TransactionNumber. The component will then use the detail aggregate data to build and send the specific poll response to the host.

If no aggregate is specified, the component will send a negative response to the specific poll inquiry.

Note FDMS does have time constraints on when a response should be sent and received by the host which can be as low as 4 seconds. Therefore the handling and specifying of the Aggregate should occur in a timely manner to ensure that all requests/responses can be processed without the connection being closed.

SSLServerAuthentication Event (FDMSOmahaBatchMgr Module)

Fired after the server presents its certificate to the client.

Syntax

• Swift
• Objective-C

func onSSLServerAuthentication(certEncoded: Data, certSubject: String, certIssuer: String, status: String, accept: inout Bool)

- (void)onSSLServerAuthentication:(NSData*)certEncoded :(NSString*)certSubject :(NSString*)certIssuer :(NSString*)status :(int*)accept;

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 (FDMSOmahaBatchMgr Module)

Shows the progress of the secure connection.

Syntax

• Swift
• Objective-C

func onSSLStatus(message: String)

- (void)onSSLStatus:(NSString*)message;

Remarks

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

Status Event (FDMSOmahaBatchMgr Module)

Shows the progress of the FDMS/Datawire connection.

Syntax

• Swift
• Objective-C

func onStatus(message: String)

- (void)onStatus:(NSString*)message;

Remarks

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

Note: This event is not fired when TransportProtocol is set to '1' (VPN Connection).
