TransFirst

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.

TransFirst

TransFirst can process a wide variety of transactions, including eCheck / ACH payments, profile-based payments, and subscriptions. 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 TransFirst Gateway, and use your merchant ID and the security key as the first two parameters for every plug-in function call that performs a transaction. You'll receive these from TransFirst once you obtain a merchant account. In the function signature template, you may see the terms merchant account name and transaction key instead of merchant ID and security key. 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; 
hostedKey; ; ...) ]

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("TransFirst")]

Returns: 1 if a valid gateway is provided, "ERROR" on failure.

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

Set Variable [$gateway; Value:CCSetGateway("TransFirst"; "cardPresent=true")==Processing Payments==

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

This simple example will run a single charge and requires you to input a card number and expiration date. To prevent this information from being saved in your database and to simplify PCI compliance, jump to the #Payment Profiles section.

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)

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; 
hostedKey;
chargeAmount;
cardNumber;
expDate)]

Returns: a verification code 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.

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; 
hostedKey;
chargeAmount;
cardNumber;
expDate;
"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)
poNumber	an arbitrary PO number for your records
chargeDescription	brief description of the charges
orderId	an arbitrary order ID for your records
firstName	First (given) name of the credit card holder
lastName	Last (surname) of the credit card holder
address	the billing address
zip	the billing address zip

Processing ACH Payments

Plastic now supports payments via direct bank transfers and eChecks, via ACH payments. To take a payment via eCheck, use the CCProcessPaymentACH function after calling the gateway.

Set Variable [$result; Value:
CCProcessPaymentACH ( 
merchantId; 
hostedKey; 
dollarAmount;
accountNumber; 
routingNumber;
""; 
accountType; 
accountHolderFirstName; 
accountHolderLastName;
"";
"checkType=" )]

Notice the blanks-- normally you should pass in a bank name and a check number in those positions, but TransFirst does not require that information. It does, however, require a check type, so use the key=value syntax to pass in that required parameter.

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)
poNumber	an arbitrary PO number for your records
chargeDescription	brief description of the charges
orderId	an arbitrary order ID for your records
firstName	First (given) name of the credit card holder
lastName	Last (surname) of the credit card holder
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;
hostedKey;
chargeAmount;
"";
"";
"swipe=%B1234123412341234^LAST/FIRST/^1112101000000000011100111000000?")]

Voiding Transactions

Set Variable [$result; Value:
CCVoidPayment (
merchantId ;
hostedKey ;
previousTransactionID)]

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.

Parameters:

merchantId - your payment gateway merchant account name
hostedKey - your merchant account password OR transaction key.
previousTransactionID - the transactionId of a previously processed transaction.

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

See also: CCLastPaymentTransactionID: 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).

With TransFirst, you should also pass in the method of payment used: ACH or CC with "methodOfPayment="

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;
  hostedKey;
  transactionID;
  cardNumber;
  dollarAmount)]

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

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.

To do an unlinked credit with TransFirst, pass in the blank transaction ID. It will be a little different based on whether it was a ACH or credit card:

Credit Card Unlinked Refund	ACH Unlinked Refund
Set Variable $result Value: CCRefund( merchantId, hostedKey; ""; cardNumber; chargeAmount; "expirationDate=12/13")	Set Variable $result Value: CCRefund( merchantId, hostedKey; ""; accountNumber; chargeAmount; "routingNumber=" "checkType=")

CCRefund also allows you to submit an optional orderId. With a credit card refund, you can also pass in the verificationCode, poNumber, chargeDescription, firstName, lastName, address, and zip.

Subscription Services

With subscriptions, payments can automatically be debited to a credit card or a bank account on a time period you specify. If you gateway supports it, there may be up to five functions used to manage subscriptions: CCCreateSubscription, CCCreateSubscriptionACH, CCModifySubscription, CCModifySubscriptionACH, and CCDeleteSubscription.

TransFirst supports all every function but deletions. To cancel a subscription, modify its properties instead. Creating and modifying subscriptions all accept the same optional parameters, available in the table below.

Valid pay periods include monthly, quarterly, yearly, weekly, bi-weekly, every4weeks, and every8weeks. The number of installments specify how many transactions to run. A six month subscription would specify a payPeriod of monthly, and 6 installments.

To create a credit card subscription, use CCCreateSubscription. To create a bank account subscription, use CCCreateSubscriptionACH. Italicized items are optional.

CCCreateSubscription	CCCreateSubscriptionACH
merchantId	merchantId
hostedKey	hostedKey
dollarAmount	dollarAmount
cardNumber	accountNumber
expirationDate	abaRoutingNumber
"";	"";
numberOfInstallments	accountType
startDate	accountHolderFirstName
payPeriod	accountHolderLastName
"";	"";
	numberOfInstallments
	startDate
	payPeriod
	"";

Returns: the ID of the subscription created, "ERROR" on failure.

After a subscription has been created, it can be modified with CCModifySubscription. If the original subscription was a bank account you'll use CCModifySubscriptionACH. The optional parameters can be set to "" if you do not need to modify them. The last two, marked with ""; are payPeriod and frequency, which cannot be modified.

CCModifySubscription	CCModifySubscriptionACH
merchantId	merchantId
hostedKey	hostedKey
previousSubscriptionId	previousSubscriptionId
dollarAmount	dollarAmount
cardNumber	accountNumber
expirationDate	abaRoutingNumber
subscriptionName	bankName
numberOfInstallments	accountType
startDate	accountHolderFirstName
payPeriod	accountHolderLastName
"";	"";
	numberOfInstallments
	startDate
	payPeriod
	"";

Click Expand to see the list of optional parameters for creating and modifying subscriptions:

Parameter
firstName	lastName
address	zip

Returns: 1 on success, or "ERROR" if there was a problem.

Payment Profiles

Creating Payment Profiles

Payment profiles allow you to save payment information straight to the gateway for future use. To create a payment profile, call either CCProfileCreatePayment or CCProfileCreatePaymentACH, depending on whether the payment profile is a credit card or ACH. Credit cards are created with CCProfileCreatePayment and updated with CCProfileUpdatePayment.

CCProfileCreatePayment	CCProfileUpdatePayment
merchantId	merchantId
hostedKey	hostedKey
customerProfileId	customerProfileId
cardNumber	paymentProfileId
expirationDate	cardNumber
	expirationDate

Returns: Creating a payment will return the ID of the profile created, "ERROR" on failure. Updating will return 1 on success, "ERROR" on failure.

After creation, payments can be retrieved with CCProfileGetPayment. Payments can be deleted with CCProfileDeletePayment.

CCProfileGetPayment	CCProfileDeletePayment
merchantId	merchantId
hostedKey	hostedKey
customerProfileId	customerProfileId
paymentProfileId	paymentProfileId

Returns: Getting a payment will return the ID of the profile requested, "ERROR" on failure. Deletions will return 1 on success, "ERROR" on failure.

Card number and expiration dates are not required when updating the payment.

When retrieving information about a profile with CCProfileGetCustomer, CCProfileGetShipping, or CCProfileGetPayment, the response will return a list of values marked with a dollar sign, like so:

$billingFirstName="First";$billingLastName="Name";$billingCompany="";

To parse out these values, you can use a combination of the Evaluate and Let functions. After seeing a response from the gateway, note the value you want to parse, such as $billingLastName in the example above. Then you can use the formula:

Evaluate ( "Let([" & Transaction::Response Message& "] ; $billingLastName)")

Which will return the last name of the profile requested.

ACH payments are added and updated in much the same way as a credit card. Italicized items are optional, and can accept ""; if not needed. ACH payments can use the same CCProfileGetPayment and CCProfileDeletePayment as above.

CCProfileCreatePaymentACH	CCProfileUpdatePaymentACH
merchantId	merchantId
hostedKey	hostedKey
customerProfileId	customerProfileId
accountNumber	paymentProfileId
routingNumber	accountNumber
"";	routingNumber
accountType	bankName
accountHolderFirstName	accountType
accountHolderLastName	accountHolderFirstName
	accountHolderLastName

For TransFirst, creating and updating payments accept the following:

Parameters
poNumber	chargeDescription
firstName	lastName
companyName	address
address	zip
orderId

Returns: Creating a payment will return the ID of the profile created, "ERROR" on failure. Updating will return 1 on success, "ERROR" on failure.

Running Charges Against Profiles

To process a payment after it has been saved, use CCProfileProcessPayment.

CCProfileProcessPayment

merchantId

hostedKey

customerProfileId

paymentProfileId

dollarAmount

"methodOfPayment="

"customerId="

"verificationCode="

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

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.
