Please, review the Developer Guide to determine the best integration approach, before diving into the API Documentation below.

API Documentation

Overview

The following document will give a good idea of how to use our Payment Gateway Client API (PGCApi), which have wrappers for other languages (VB, JS, etc) This is a simpler value pair operation library

Elements

The library has two basic elements

Connection

Client can either connect directly to
a)Cloud9 Server Payment Web Controller (PWC) - this is a good option is local hardware payment terminals are not used
b)Local Payment Device Controller (PDC), which controls the payment terminal.

Payment Processing Session

an object that holds description of the transaction and it's result.

Basic Flow

1. Initialize
2. Connect
   :repeat as many times as necessary
3. Create New Session
4. Set Session Parameters
5. Send Request
6. Get Response
7. Close the Session
   :go back to create a new session, if more transactions needed
8. Disconnect

Detailed Flow with C Examples

1. Initialize the library
   PgcInit("PgcSample");
2. Connect to the Payment Web Controller (PWC - direct Cloud9 Server connection) or local Payment Device Controller (PDC) Server
   1. Create Connection Handle
      int nConn = PgcNewConn(PGC_SVC_C9PG_PDC, "Name", "Token", PGC_TIMEO_TXN_UI, "PgcSample", ""); //USE PGC_SVC_C9PG_PWE_TEST for PWE
   2. Open the Connection, specified by Connection Handle
      int nErr = PgcConnect(nConn);
3. Create New Session
   int nSess = PgcNewSess(nConn, 1);
4. Set Session Parameters
   1. Set MID/TID/PWD
      PgcSetStr(nSess, 0, PGC_GWKEY_GMID, "1001396250"); // Gateway merchant ID
PgcSetStr(nSess, 0, PGC_GWKEY_GTID, "GT1001396253"); // Gateway terminal ID
PgcSetStr(nSess, 0, PGC_GWKEY_GMPW, "123"); // Gateway merchant password
   2. Set Transaction Type
      PgcSetStr(nSess, 0, PGC_GWKEY_TXNACT, PGC_GWVAL_TXNACT_AUTH); // Transaction action type -> authorization
   3. Set Transaction Medium (e.g. Credit Card)
      PgcSetStr(nSess, 0, PGC_GWKEY_MDM, PGC_GWVAL_MDM_CREDIT); // Payment medium -> credit card
   4. Set Transaction Parameters (e.g. Amount, Tax, Trace#)
      PgcSetAmt(nSess, 0, PGC_GWKEY_MAINAMT, 123); // Main amount -> $1.23
PgcSetAmt(nSess, 0, PGC_GWKEY_INCTAXAMT, 8); // Included tax amount -> $0.08
PgcSetStr(nSess, 0, PGC_GWKEY_SRCTRACENUM, "123456"); // Source trace number; will be returned for matching
5. Send the Request for this Session
   int nErr = PgcRequest(nSess);
6. Get Response and Approval Code for the Session
   PgcGetStr(nSess, 0, PGC_GWKEY_STATUS, sStatus, 256); // Transaction status, indicating if it is successful
...
PgcGetStr(nSess, 0, PGC_GWKEY_RSPCODE, sRspCode, 256); // Response code returned from the host
...
PgcGetStr(nSess, 0, PGC_GWKEY_RSPTEXT, sRspText, 256); // Response text returned from the host
...
PgcGetStr(nSess, 0, PGC_GWKEY_AUTHCODE, sAuthCode, 256); // Auth code
7. Close the Session
   PgcFreeSess(nSess);
8. Disconnect from Server
   PgcDisconnect(nConn); // Disconnecting from the controller; will be called automatically upon closing
PgcFreeConn(nConn); // Closing connection to the controller; called once per connection
9. Un-Initialize
   PgcUninit("PgcSample"); // Uninitializing library; called once per application upon exit
