This guide is for developers using the DLL

Inventory

To begin with, you will need the following:

1) The interface header file CLCAPIW.h located in 911\BIN directory. This header contains the ENTIRE listing of available API.

2) The library file CLCAPIW2.DLLlocated in 911\DATA directory.

Language Specific Instructions

Visual Basic

• In VB you need to declare all the parameters using the ByVal prefix instead of ByRef. This includes the strings.
• If you would like to use an OCX instead for Visual Basic, you can use CLClient.ocx in the same directory. Another alternative is File Based Communication.

 Public Declare Function clcInit Lib "CLCAPIW2.dll" (ByVal ClientName As String, ByVal ServerName As String As Integer)

C++/C#

• The Header file is the regular WIN32 header file. The data type LONG is 32 bit.
• Keep in mind that in C# and any .NET environment for instance, LONG is 64 bit so you have to use int or Integer not LONG ot Long in your definitions.
• In C, the path has to be of format "C:\\911\\DATA", because back-slash is the escape char

 DllImport("CLCAPIW2.dll", EntryPoint="clcInit", SetLastError=true, ExactSpelling=true, CallingConvention=CallingConvention.StdCall)

 public static extern int clcInit(string ClientName, string ServerName);

Call Sequences

On Startup

• clcInit → Set the client name and server name for communications
• clcSetJournalDir → Set the directory where the credit card journal is, e.g. 911\DATA
• clcSetMessageDir → Set the directory where the file communications occur, e.g. C:\911\MESSAGES

 NOTE: the directories are actual directories on the server (where the dll is installed)

• clcSetStationId → Set a unique number for the terminal

On Shutdown

• clcTerm Release the resources

On Start Dial

• clcSetMerchantIndex → Optional, use a different merchant than the default
• clcSetAccountNum → Set the card account number (for manual entry)
• clcSetTrackData → Set the scanned track data (for magnetic swipe)
• clcDial → Start to dial the processor, connect before sending the transaction

 Note: do not call clcSetAccountNum after clcSetTrackData
 or the transaction will go through as type manual not scanned

On Regular Authorization

• clcSetMerchantIndex → Optional, use a different merchant than the default
• clcSetInvoiceId → Set the invoice number
• clcSetOperatorId → Set the operator number
• clcSetTableNum → Set the table number

• clcSetExpDate → Set the expiration date (for manual entry)
• clcSetTrackData → Set the scanned track data (for magnetic swipe)
• clcSetAmount → Set the authorization amount ($20.01 is entered as 2001 )
• clcSetCVCNumber → Set the CVC Number
• clcSetAVSData → Set the AVS Data (e.g. Zip)
• clcAuth → Do the authorization, returns the Transaction Id if successful. Auths cannot be settled until Tip is added
• clcSale → Do the sale, returns the Transaction Id if successful
• clcGetAuthCode → Get the authorization code if successful
• clcGetErrText → Get the error text if failed

On Regular Force

• clcSetMerchantIndex → Optional, use a different merchant than the default
• clcSetInvoiceId → Set the invoice number
• clcSetOperatorId → Set the operator number
• clcSetTableNum → Set the table number
• clcSetPaymentType → Set the payment type
• clcSetGuestCount → Set the guest count
• clcSetAccountNum → Set the card account number (for manual entry)
• clcSetExpDate → Set the expiration date (for manual entry)
• clcSetTrackData → Set the scanned track data (for magnetic swipe)
• clcSetAmount → Set the authorization amount
• clcSetAuthCode → Set the force auth code (acquired from the call center)
• clcSetCVCNumber → Set the CVC Number
• clcSetAVSData → Set the AVS Data (e.g. Zip)
• clcForce → Actual do the force, returns the Transaction Id if successful

On Regular Credit

• clcSetMerchantIndex → Optional, use a different merchant than the default
• clcSetInvoiceId → Set the invoice number
• clcSetOperatorId → Set the operator number
• clcSetTableNum → Set the table number
• clcSetPaymentType → Set the payment type
• clcSetGuestCount → Set the guest count
• clcSetAccountNum → Set the card account number (for manual entry)
• clcSetExpDate → Set the expiration date (for manual entry)
• clcSetTrackData → Set the scanned track data (for magnetic swipe)
• clcSetAmount → Set the authorization amount
• clcSetCVCNumber → Set the CVC Number
• clcSetAVSData → Set the AVS Data (e.g. Zip)
• clcSetAuthCode → Set the force auth code (acquired from the call center)
• clcCredit → Do the credit, returns the Transaction Id if successful

On Add Tip

• clcSetMerchantIndex → Optional, use a different merchant than the default
• clcAddTip → Add actual tip to the transaction, need the Transaction Id

On Void Transaction

• clcSetMerchantIndex → Optional, use a different merchant than the default
• clcVoid → Void the transaction, need the Transaction Id

On Batch

• clcSetMerchantIndex → Optional, use a different merchant than the default
• clcBatch → Batch

On Gift Card Transaction

• clcActivate → Optional, activate gift card
