FDMSLevel3 Class

Properties   Methods   Events   Config Settings   Errors  

The FDMSLevel3 class is a tool used to create Level 3 Corporate Purchasing Card addendum aggregates, which can then be passed to the FDMSSETTLE class and settled.

Syntax

dpaymentssdk.Fdmslevel3

Remarks

This Level3Extension class creates Level 3 addendum data, which can be sent in the settlement to achieve a better interchange rate when accepting corporate purchasing cards. The Level 3 addendum allows the merchant to send very detailed information about every item that was purchased by the card holder, as well as tax and shipping information.

This class creates a different addendum aggregate based on the CardType. Visa and MasterCard addendums differ slightly, and therefore a slightly different set of properties are required for each.

The following example illustrates how to build a Level 3 addendum for the fctVisa CardType: //First, authorize the credit card FDMSECommerce.TransactionAmount = "2720"; // $27.20 FDMSECommerce.Authorize(); //Then, put the result into the settlement component FDMSSettle.DetailRecords.Add(New FDMSRecordType(FDMSECommerce.GetDetailAggregate())) //Then build the Level 2 portion FDMSLevel2.CardType = fctVisa; FDMSLevel2.CommercialCardType = FDMSECommerce.ResponseCommercialCard; FDMSLevel2.OrderDate = "230928"; // September 28th, 2023 FDMSLevel2.FreightTaxAmount = "0"; FDMSLevel2.FreightAmount = "600"; // $6.00 FDMSLevel2.PurchaseIdentifier = "123456PURCHID"; FDMSLevel2.ShippedToZip = "90210"; FDMSLevel2.ShippedFromZip = "90210"; FDMSLevel2.TaxAmount = "120"; // $1.20 //Now build the Level 3 portion FDMSLevel3.CardType = fctVisa FDMSLineItem item = new FDMSLineItem(); item.Quantity = 2; item.UnitCost = "500"; // $5.00 item.Units = "each"; item.TaxAmount = "60"; // $0.60 item.Total = "1060"; // $10.60 FDMSLevel3.LineItems.Add(item); item = new FDMSLineItem(); item.Quantity = 25; item.QuantityExponent = "1"; item.UnitCost = "400"; // $4.00 item.Units = "each"; item.TaxAmount = "60"; // $0.60 item.Total = "1060"; // $10.60 FDMSLevel3.LineItems.Add(item); //Finally, add the Level 2 and Level 3 addendum data to the settlement at the same index //as the associated transaction. FDMSSettle.DetailRecords[FDMSSettle.DetailRecords.Count()].AddendumAggregate = FDMSLevel2.GetAddendum() + FDMSLevel3.GetAddendum()

A Level 3 addendum for the fctMasterCard CardType is constructed similarly:

NOTE: You must send both a Level 2 addendum and a Level 3 addendum together in the same DetailAddendum. Level 3 data cannot be processed without a corresponding Level2 aggregate (however, you can send Level 2 data without Level 3 data).

List of valid Line Item properties for Mastercard:

An example of setting two line items for a Visa Corporate purchasing card follows:

FDMSLevel3.CardType = fctVisa FDMSLevel3.LineItems.Add(new FDMSLineItem()); FDMSLevel3.LineItems[0].CommodityCode = "4900" // Books and printed materials FDMSLevel3.LineItems[0].Description = "Reference manual" FDMSLevel3.LineItems[0].DiscountAmount = "" // No discount FDMSLevel3.LineItems[0].ProductCode = "ISBN123456" FDMSLevel3.LineItems[0].Quantity = "2" FDMSLevel3.LineItems[0].QuantityExponent = "0" FDMSLevel3.LineItems[0].UnitCost = "500" // $5.00 FDMSLevel3.LineItems[0].TaxAmount = "60" // $0.60 FDMSLevel3.LineItems[0].TaxRate = "600" // 6.00 percent FDMSLevel3.LineItems[0].Total = "1060" // $10.60 FDMSLevel3.LineItems[0].Units = "each" FDMSLevel3.LineItems.Add(new FDMSLineItem()); FDMSLevel3.LineItems[1].CommodityCode = "4900" // Books and printed materials FDMSLevel3.LineItems[1].Description = "Quick Start manual" FDMSLevel3.LineItems[1].DiscountAmount = "" // No discount FDMSLevel3.LineItems[1].ProductCode = "ISBN654321" FDMSLevel3.LineItems[1].UnitCost = "1000" // $10.00 FDMSLevel3.LineItems[1].Quantity = "1" FDMSLevel3.LineItems[1].TaxRate = "600" // 6.00 percent FDMSLevel3.LineItems[1].TaxAmount = "60" // $0.60 FDMSLevel3.LineItems[1].Total = "1060" // $10.60 FDMSLevel3.LineItems[1].Units = "each"

Please refer to the FDMSLineItem type for a complete list of fields.

MerchantTaxId Property (FDMSLevel3 Class)

Merchant's tax Id number assigned by the taxing authority.

Syntax


public String getMerchantTaxId();


public void setMerchantTaxId(String merchantTaxId);

Default Value

""

Remarks

This property contains the VAT identification number of the merchant from whom the goods or services were purchased.

The maximum length of this property is 20 characters.

This property is only used for Visa Corporate Purchasing Cards.

Config Method (Fdmslevel3 Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String 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.

GetAddendum Method (Fdmslevel3 Class)

Returns a Level 3 Purchasing card addendum based on the specified CardType .

Syntax

public String getAddendum();

Remarks

The type of addendum created by this class depends upon the value of the CardType property. Different addendums are created when the CardType is set to fctVisa or fctMasterCard, and different properties are required for the two different CardTypes.

Config Settings (Fdmslevel3 Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable:   Whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The class will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the class does not attempt to process external events.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseDaemonThreads:   Whether threads created by the class are daemon threads.

If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value is True.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.

This setting is set to false by default on all platforms.
