Cloud9 Payment Gateway Documentation. This site can also be reached at http://docs.cloud9paymentgateway.com

Step One

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

Online API Documentation

Cloud9 Payment Gateway Documentation

→ Please, see Payment Gateway C-languages Documentation

JSON Sandbox

→ Online Documentation: C9 API Documentation & Sandbox
We recommend that you browse through the API intro below, first.

REQUIRED LIBRARIES plus Live Sample and Source Code

Windows Development Environment is contained in the Windows Integration Samples
→ NOTE: It is highly recommended that you use the live Windows Integration Samples, which have real time source code windows to help you understand the API.

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 Transaction Session

an object that holds description of the transaction and it's result. There is one transaction per session

Connection Types

1. Payment Device Controller (PDC) Connection:Connects to the local device driver - wss://localhost:5556/
   Advantage: Offline Store & Forward Capability
   Disadvantage: Needs local software install
   
   
2. Web Based Payment Device Controller (PWC):Connects directly to the Cloud9 server - https://testlink.c9pg.com:5558/hj
   Advantage: No local software required, unlimited cross platform capability
   Disadvantage: No Offline Store & Forward Capability
   
   
   

Basic Flow

1. Initialize
2. Connect
   repeat as many times as necessary
3. Create New Transaction Session
4. Set Transaction Parameters (uses simple Set String and Set Value commands)
5. Send Transaction Request
6. Get Transaction Response (uses simple Get String and Get Value commands)
7. Close the Session
   go back to create a new transaction 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 Transaction 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 Transaction Request
   int nErr = PgcRequest(nSess);
6. Get Transaction Response and Approval Code
   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 Transaction 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

Using API Documentation

• There are two main files of interest:
  

PgcClient.h

contains functions

PgcKey.h

contains parameter definitions for the key pairs

You can use the File List and File Member functions like so, to get more detail on what is available.
You can also use Search to find a function

This is how you can browse the parameter definitions
