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
- 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 ($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
Note: do not call clcSetAccountNum after clcSetTrackData or the transaction will go through as type manual not scanned
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
- clcDeactivate → Optional, deactivate gift card
- clcInquire Optional, returns the balance on the gift card
- clcSale → Do the sale, returns the Transaction Id if successful. Add tip is not supported, so clcAuth does not apply
- clcCredit → Do the credit, returns the Transaction Id if successful
Hotel Specific
- clcSetCheckInDate → Sets checkin date
- clcSetCheckOutDate → Sets checkout date
- clcSetRoomRate → Sets room rate
- clcSetCustomerLastName → Sets customer last name
- clcSetCustomerFirstName → Sets customer first name
