The FDMSHealthCare component is an advanced tool used to authorize FSA cards for healthcare transactions in either a retail or e-commerce/moto environment. This component makes authorizing these types of transactions very easy. Supported Industry Types include retail stores, direct marketing (e-commerce and mail order/phone order) and grocery or food stores.
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 FDMSHealthCare component makes authorizing healthcare and FSA card transactions 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.
FDMSHealthCare.MerchantNumber = "000000999990"; 'Supplied by FDMS/Datawire FDMSHealthCare.MerchantTerminalNumber = "555555"; 'Supplied by FDMS/Datawire FDMSHealthCare.TPPID = "VNT001"; 'Supplied by FDMS/Datawire FDMSHealthCare.VisaIdentifier = "0B34567890123456789"; 'Supplied by FDMS/Datawire FDMSHealthCare.DatawireId = "0000B47FFFFFFFFFFFFF"; 'Retrieved with the FDMSRegister component. FDMSHealthCare.URL = "https://staging1.datawire.net/sd/"; 'Retrieved with the FDMSRegister component.
Then set the Card fields with the customer's cardholder data. Most card readers are capable of reading both Track1 and Track2
data off of a credit card. If both are present and correctly read, you should default to sending Track1 data.
If your card reader cannot read the card at all, you may manually enter the credit card number and expiration date. If your IndustryType
is set to itDirectMarketing, you may only use manual entry. Do not forget to set the EntryDataSource
field, as it is used by the component during authorization to create the proper type of payload.
FDMSHealthCare.Card.MagneticStripe = "B4662060000000005^FDCS TEST CARD^120410123456789" FDMSHealthCare.Card.EntryDataSource = edsTrack1
Next, set properties that contain details about the transaction. The TransactionNumber should be incremented for every transaction you authorize. The TotalMedicalAmount and TransactionAmount must now be set, along with any optional amounts such as PrescriptionAmount, VisionAmount, DentalAmount, or ClinicAmount. Please note that the TotalMedicalAmount need not equal the TransactionAmount, but it CANNOT be greater than the TransactionAmount. All amounts are set with an implied decimal point (ie: $1.00 is "100"). The IndustryType should also be set at this time, as it will indicate whether this transaction is made for a Retail store, e-commerce, or a grocery store.
FDMSHealthCare.TransactionNumber = 1 FDMSHealthCare.PrescriptionAmount = "6000" FDMSHealthCare.TotalMedicalAmount = "8000" FDMSHealthCare.TransactionAmount = "20200" FDMSHealthCare.IndustryType = itRetail
Finally, submit the transaction via the Authorize method.
FDMSHealthCare.Authorize()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).
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.
Note that FSA cards may be only partially approved. If the card is authorized for less than the full amount, the ApprovalCode field will begin with "AL" instead of "AP", and the AuthorizedAmount will contain the amount that was actually removed from the card. The customer must then pay the remainder via another means. If the customer cannot pay the remainder or wishes to cancel the transaction, use the ReversePartialAuth method to reverse the authorization.
A fully authorized transaction may also be reversed by using the ReverseFullAuth method. Reversals are used instead of voids for FSA cards because the block on the customer's FSA card is immediately released and funds are quickly made available for use. The customer does not have to wait for the block to expire before he can use his FSA card again.
