VirtualMerchant

Working with Plug-ins

Plastic is a plug-in for FileMaker Pro and FileMaker Server that processes secure payments within FileMaker.

Requirements

FileMaker 7 or higher, Java Virtual Machine (JVM) 6 or higher, Windows or Mac OS X 10.6. Rosetta on Intel Macs not supported.

Installation

If you unzip the zip archive containing the plug-in files and open the top-level directory, you will find two subdirectories labeled WIN (for Windows) and MAC (for Macintosh). The WIN directory contains two plug-in files, one with a .fmx extension and another with a .fmx64 extension. The file with the .fmx64 extension is only used for FileMaker Server installations, which are explained below. The MAC directory contains a plug-in file with a .fmplugin extension.

To install the plug-in, copy the plug-in from the WIN or MAC folder to one of the directories listed below. Directory paths are listed relative to the parent directory of the installation home directory of the FileMaker application.

FileMaker Pro

FileMaker Pro XX/Extensions

FileMaker Pro XX Advanced/Extensions

FileMaker Server Web Publishing Engine (applies to the entire Web Publishing Engine prior to FileMaker Server 12.0.2 and to Instant Web Publishing only for FileMaker Server 12.0.2 and later)

FileMaker Server/Web Publishing/publishing-engine/wpc/Plugins (create the Plugins folder if it does not exist)

FileMaker Server Custom Web Publishing (applies only to FileMaker Server 12.0.2 and later)

FileMaker Server/Web Publishing/publishing-engine/cwpc/Plugins (create the Plugins folder if it does not exist)

Note: For 64-bit versions of Windows, be sure to use the 360Works plug-in with a .fmx64 extension

FileMaker Server Scripting Engine (applies to FileMaker Server scheduled scripts)

FileMaker Server/Database Server/Extensions

Note: Using the plug-in with the FileMaker Server Web Publishing Engine or the FileMaker Server Scripting Engine requires an Enterprise plug-in license.

Uninstalling the plug-in

Uninstall the plug-in by quitting FileMaker Pro or stopping FileMaker Server and removing the plug-in file from the appropriate Extensions or Plugins directory.

Demo mode and registering the plug-in

Plug-ins will run in a fully featured demo mode until they are registered. While running in demo mode, the plug-in will run for 2 hours at a time. In order to get another two hours of demo time, you must restart FileMaker Pro, FileMaker Server's database server module or FileMaker Server's Web Publishing Engine, depending upon where the plug-in is installed.

To register the plug-in in FileMaker Pro, you may either enter the license information in FileMaker plug-in preferences or by calling CCRegister inside a script. You must call CCRegister inside a script in order to register the plug-in for use with FileMaker Server.

Set Variable [ $register; Value: CCRegister ( $licenseKey, $registeredToName) ]

Returns: a 1 on success or a 0 on failure.

Error Handling/Reporting

When something unexpected happens, the plug-in will pop up a dialog showing what the error message is. This makes it easy to see what went wrong. However, in some cases, you (the developer) may prefer to show your own message to the user, or possibly not show a message at all. In that case, you can call CCSetErrorCapture ( true ). This will suppress the displaying of error dialogs.

Whether or not you suppress the error dialogs, a plugin function will return the word "ERROR" if something goes wrong. It's a good idea to check the result of each plugin function call to determine if an error occurred. If an error occurs, use the CCLastError function to get a detailed message describing the error. For example:

Set Variable [ $result = MyPluginFunction("x" ; "y" ; "z") ]
If [ $result = "ERROR" ]
  Show Custom Dialog [ "An error occurred: " & CCLastError ]
End If

If a plug-in is not installed correctly, all plug-in function calls will return "?"

To check if a transaction succeeded

The simplest way to check to see if money has changed hands in a payment processing function call is to check the result of the function itself. This is extremely useful when calling functions such as CCProcessPayment and CCProfileProcessPayment. The result of the transaction will give a transaction ID or the word ERROR. Using the CCLastError like in the example above will give further information about the error, such as if there is no network connectivity, or the card was declined.

Set Variable[$result ; CCProcessPayment(...)]
If[$result = "ERROR"]
	#Transaction is unsuccessful. Below is an example of how you might handle the error. 
	Set Field[Transaction::Error Message ; CCLastError]
Else
	#Transaction is successful.
	Set Field[Transaction::Transaction ID ; $result]
End If

More Information

For more information on how to correctly install and work with plug-ins, check out the Plugins 101 documentation.

VirtualMerchant

VirtualMerchant can process a variety of transactions, including voids, refunds, card not present and swiped cards, as well as recurring charges.. For detailed examples of each of these transactions, check the demo file included as a download with Plastic. These scripts are ready for insertion into your own solution!

Getting an account

You'll need an account using the Virtual Merchant Gateway, and use your merchant ID and the PIN as the first two parameters for every plug-in function call that performs a transaction. You'll also need the user name, provided by Virtual Merchant, provided as an additional but required parameter. In the function signature template, you may see the terms merchant account name and transaction key instead of merchant ID and PIN. This is due to the fact that Plastic supports many gateways that use different definitions of log-in credentials.

Set Variable [ $result; Value:
CCProcessPayment (
merchantID;
pin;
"user=joe" ...) ]

Setting the Gateway

Before processing any payments, you need to tell Plastic which gateway you are using. This is done by calling CCSetGateway.

Set Variable [$gateway; Value:CCSetGateway("VirtualMerchant")]

Returns: 1 on success, "ERROR" on failure.

If running card present charges, you should also set cardPresent to true when setting the gateway.

Set Variable [$gateway; Value:CCSetGateway("VirtualMerchant"; "cardPresent=true")

Test Mode

To run test transactions, call CCSetTestMode - If set to 1, tells Plastic to perform all subsequent transactions as test transactions. If set to 0, tells Plastic to perform all subsequent transactions as live transactions. If this function is never called, the default behavior of Plastic is to treat all transactions as live transactions.

Emulators And Alternate URLs

If you would like to use Plastic to perform transactions against an alternate URL, call the CCSetGateway function with the additional parameter url, whose value would correspond to the alternate url. A gateway emulator is a common use case for an alternate URL. Gateway emulators fashion an application programming interface that resembles that of a competing gateway to ease the integration process for merchants who switch to their gateway.

Example of communicating with a gateway that provides an Authorize.Net emulator at the URL http://AlternateURLGoesHere.com

Set Variable [$result; Value:CCSetGateway ("Authorize.Net" ; "url=http://AlternateURLGoesHere.com/")]

The call to CCSetGateway acts as a flag, so all subsequent transactions will point to the alternate URL until otherwise specified or FileMaker is restarted.

Processing Payments

Basic Credit Card Charge

Once you properly configure your merchant account, you can quickly and easily process payment transactions.

You must provide the following information for a credit card payment transaction:

• merchant account name (this might also be known as a store id)
• transaction key (this might also be known as a password or token)
• dollar amount
• credit card number
• credit card expiration date (Format the expiration date as MMYY or MM/YY or MM/DD/YY)
• VirtualMerchant user

The CCProcessPayment function will process a transaction and return a transaction ID. This function returns a transaction ID if the transaction is successful or the word ERROR if the transaction fails. For detailed information about the most recent transaction failure, call the CCLastError function before calling any other transaction-processing function.

In your script, you would then have a second line after setting the gateway.

Set Variable $result Value: 
CCProcessPayment(
merchantID, 
PIN;
chargeAmount;
cardNumber;
expDate;
"user=demoaccount")

Returns: the transactionID from the payment gateway service if the order is successful, or "ERROR" if there was a problem

Note: It is important to store the resulting transaction ID because you may need it later to void the transaction, issue a refund or capture a previously authorized transaction.

Since the user is a required piece of information for VirtualMerchant, but it's not part of the signature, add the information with the "key=value" syntax.

You may submit optional parameters to most of Plastic's payment-transaction processing functions. These parameters will be submitted to the payment gateway along with the basic transaction information. Although they are not usually required to process an order, these parameters can be useful for tasks such as address verification or linking a transaction to a customer id or an invoice number. To supply additional parameters to a function call, add them to the end of the parameter list after the last required parameter, using a "key=value" syntax.

Set Variable $result Value:
CCProcessPayment(
merchantID, 
PIN;
chargeAmount;
cardNumber;
expDate;
"user=demoaccount";
"chargeDescription=" & Payment::description;
"verificationCode=" & $securityCode)

Click Expand to see the list of optional parameters:

Parameter	Description
verificationCode	the numeric verification code on the credit card. This is also known as Card Security Code (CSC), Card Verification Value (CVV), Card Verification Value Code (CVVC), Card Verification Code (CVC) or Verification Code (V-Code/V Code)
invoiceNumber	an arbitrary invoice number for your records
customerId	an arbitrary customer ID for your records
address	the billing address
zip	the billing address zip

Using Card Readers

Certain types of merchant accounts are set up for reading physical card swipes, instead of taking orders via the web or over the phone. If you account is a card present account, like a retail store, then you will need to also send the data included on the magnetic stripe of a card. It is important to pass in swipe data if you have it, as your transaction may be downgraded to a more expensive rate if you simply type a card number.

First, set the gateway with card present parameter

To process a card present transaction, first call CCSetGateway with the parameter cardPresent=true. If CCSetGateway returns a 1, then you can perform a card present transaction.

Second, determine your Track 1 and 2 formats

To process a payment using card present accounts, you'll need the information in the magnetic stripe of the credit card. In Plastic, this information may be obtained from a keyboard-emulating card reader, which essentially dumps text into a text field when the card is swiped, as if the text had been entered via a keyboard.

While some card readers will contain software that parses that raw data from the magnetic stripe before dumping it to a field, this documentation refers to those keyboard-emulating readers that dump raw data. Raw swipe data contains two delimited pieces of information: Track 1 and Track 2.

Raw data would look something like this:

%B1234123412341234^LAST/FIRSTM^1112101000000000011100111000000?;1234123412341234=11121010000000000111?

Track 1 is delimited by a percent symbol and a question mark, so in the previous example Track 1 would be:

%B1234123412341234^LAST/FIRST/^1112101000000000011100111000000?

Track 2 is delimited by a semicolon and question mark, so in the previous example Track 2 would be:

;1234123412341234=11121010000000000111?

See http://www.exeba.com/comm40/creditcardformat.htm for more information about Track 1 and Track 2.

Note: As a convenience, the Plastic function CCTrackData will parse either Track 1 or Track 2 data as a return-separated string containing account code, cardholder name, expiration date (YYMM), and optional discretionary data.

Process the payment with CCProcessPayment

Finally, call CCProcessPayment and pass in raw swipe or track data. When processing a card-present transaction, a gateway will typically require you to pass in either the full raw swipe, Track 1 or Track 2. In most cases, you do not need to pass in card numbers and expiration dates. Set Variable [$result; Value:CCProcessPayment(merchantID;PIN;chargeAmount;"";""; "user=demoaccount"; "track1=%B1234123412341234^LAST/FIRST/^1112101000000000011100111000000?")]

Pass in either track1 or track2.

Voiding Transactions

Set Variable [$result; Value: 
CCVoidPayment ( 
merchantID ; 
PIN ; 
previousTransactionID;
"user=demoaccount")]

Voids a previously processed payment. The parameters are similar to the CCProcessPayment function, except dollarAmount is replaced with the addition of the previousTransactionID parameter. The previousTransactionID should be the transaction ID of the transaction you wish to void. This value is returned by the CCProcessPayment function. Alternately, you can use the CCLastPaymentTransactionID function to get the transactionID of the last processed payment.

Note that CCVoidPayment will only work on orders that have not settled yet, which means that it will generally only work on payments made that same day. To void settled orders, use CCRefund instead.

Returns: the transaction ID from the payment gateway service if the order is successful, or "ERROR" if there was a problem

See also: CCLastPaymentTransactionIDReturns: the transactionID from the payment gateway service if the order is successful, or "ERROR" if there was a problem (use CCLastError for more detailed information about the nature of the error)

Crediting or Refunding Transactions

To credit a transaction, you need the transaction ID returned by CCProcessPayment. Pass this (along with other payment info) to the CCRefund function. This is similar to the void process, except it accepts a dollar amount and the credit card number (or the last four digits of the credit card number) used to process the original transaction.

Set Variable [$result; Value:
CCRefund(
    merchantID;
    PIN;	
    transactionID;
    cardNumber;
    dollarAmount;
    "user=demoaccount")]

Returns: the transactionID from the payment gateway service if the order is successful, or "ERROR" if there was a problem

If you do not pass a dollar amount, it will refund the whole amount of the transaction.

You can also use CCRefund to do an unlinked credit, which will run a refund of the amount without requiring a transaction ID. Pass in blank values ""; for the previous transaction ID to perform this type of transaction. It will be a little different based on whether it was a swiped or a typed card:

Credit Not Present Unlinked Refund	Card Present Unlinked Refund
Set Variable [$result Value: CCRefund( merchantID, PIN; ""; cardNumber; chargeAmount; "user=demoaccount"; "expirationDate=12/13")]	Set Variable $result Value: CCRefund( merchantID, PIN; ""; ""; chargeAmount; "user=demoaccount"; "track1="; "track2=")

Subscription Services

With subscriptions, payments can automatically be debited to a credit card or a bank account on a time period you specify. To create a credit card subscription, use CCCreateSubscription. After a subscription has been created, it can be modified with CCModifySubscription. Items in italics are optional.

Valid pay periods include: daily, weekly, biweekly, semi-monthly, monthly, bi-monthly, quarterly, semester, semi-annually, and annually.

CCCreateSubscription	CCModifySubscription
merchantID	merchantID
PIN	PIN
dollarAmount	previousSubscriptionId
cardNumber	dollarAmount
expirationDate	cardNumber
";	expirationDate
"";	"";
startDate	"";
payPeriod	startDate
"";	payPeriod
"user="	"";
	"user="

Returns: 1 on success, "ERROR" on failure.

Returns: 1 on success, "ERROR" on failure.

There are no optional parameters with deleting a subscription.

Getting Information

Plastic includes a number of helper functions that allow users to retrieve data from the gateway or Plastic.

To execute any of these functions inside of a script, use a Set Field or Set Variable script step.

• CCGetCardIssuer(cardNumber) - returns the card issuer for a given card number, either: VISA, MASTERCARD, AMEX, DINERS, DISCOVER, JCB. Returns an error if the card number is from another issuer.
• CCGetLast (name) - returns a value from the most recent transaction response that corresponds with the name parameter.
• CCLastAVS- returns the gateway's Address Verification System Response for the last payment which was processed. This response is typically a one letter indicator, meaning the following:

Code	Description	Network
A	Street address matches, but 5-digit and 9-digit postal code do not match.	Standard domestic
B	Street address matches, but postal code not verified.	Standard international
C	Street address and postal code do not match.	Standard international
D	Street address and postal code match. Code "M" is equivalent.	Standard international
E	AVS data is invalid or AVS is not allowed for this card type.	Standard domestic
G	Non-U.S. issuing bank does not support AVS.	Standard international
I	Address not verified.	Standard international
M	Street address and postal code match. Code "D" is equivalent.	Standard international
N	Street address and postal code do not match.	Standard domestic
P	Postal code matches, but street address not verified.	Standard international
R	System unavailable.	Standard domestic
S	Bank does not support AVS.	Standard domestic
U	Address information unavailable. Returned if the U.S. bank does not support non-U.S. AVS or if the AVS in a U.S. bank is not functioning properly.	Standard domestic
W	Street address does not match, but 9-digit postal code matches.	Standard domestic
X	Street address and 9-digit postal code match.	Standard domestic
Y	Street address and 5-digit postal code match.	Standard domestic
Z	Street address does not match, but 5-digit postal code matches.	Standard domestic

• CCLastCCV- returns the gateway's Card Code Verification Response for the last payment which was processed. This response is typically a one letter indicator, meaning the following:
  • M- CVV2/CVC2 Match - Indicates that the card is authentic. Complete the transaction if the authorization request was approved.
  • N- CVV2 / CVC2 No Match – May indicate a problem with the card. Contact the cardholder to verify the CVV2 code before completing the transaction, even if the authorization request was approved.
  • P- Not Processed - Indicates that the expiration date was not provided with the request, or that the card does not have a valid CVV2 code. If the expiration date was not included with the request, resubmit the request with the expiration date.
  • S- Merchant Has Indicated that CVV2 / CVC2 is not present on card - May indicate a problem with the card. Contact the cardholder to verify the CVV2 code before completing the transaction.
  • U- Issuer is not certified and/or has not provided visa encryption keys
• CCLastChargeResult - returns the gateway's result code for the last operation.
• CCLastPaymentAuthCode - returns the gateway's approval code for the last payment which was processed with CCProcessPayment.
• CCLastPaymentTransactionID- returns the gateway's transaction ID for the last payment which was processed with CCProcessPayment.
• CCLastRawResponse- returns the gateway's raw text response for the most recent transaction.
• CCValidateCardNumber (cardNumber) determines if a card number is valid. Does not indicate the validity of the card itself, only its number. Returns either a 1 for valid card, or 0 for invalid cards.
• CCLastError - returns the text of the last error triggered by a plugin function.
• CCLicenseInfo - returns information about the license used.
• CCVersion - returns the version of the credit card plugin which is installed.
