Overview

This section is under construction. Please contact us directly @ 561-392-9606 x 701 for information on limited Cloud9 release.

Environment & Client Options

Being a cloud based system, Cloud9 has few restrictions on the integration options. The following are some of the possibilities:

• Windows
• Unix/Linux
• Android
• iPhone
• OS X
• Custom

Services

Cloud9 Payment Gateway

Cloud9 is essentially a multi-merchant/multi processor switch. Cloud9 reduces the complexity of direct processor and payment terminal programming, certification and compliance by presenting a simple unified interface to the developer with numerous interface options. The core communications are conducted via TLS/SOAP/JSON with wrappers in C/C++/Java, if desired.

Back-Office Reporting Gateway

Cloud9 has a full suite of Back Office Reporting, which can be extended and scripted.

Payment Device Controller (PDC)

Optional Payment Device Controller (PDC) hides the complexity of low level communications with the payment terminals and adds Offline Store & Forward functionality, if desired. The client (POS/web page/mobile device, etc) can communicate with the PDC, which will in turn control the payment perminal/pin pad and relate the processing instructions to the Cloud9 Payment Gateway. This is the easiest form of integration and it is recommended.
Note: Variations of Payment Device Controller are Payment Mobile Controller (PMC) and Payment Web Controller (PWC), dealing with mobile and web based payment processing functionality respectively.

→ OPTION1: Local Payment Device Controller with Store and Forward Capability

The client can communicate with a local Payment Device Controller (PDC) via SOAP, JSON or using the wizard like wrapper, written in C/C++/Java.

→ OPTION2: No Local Software - Direct Cloud Connection to Cloud9 Payment Web Controller (PWC)

The client can communicate directly with the cloud Payment Web Controller (PWC) via SOAP, JSON or using the wizard like wrapper, written in C/C++/Java.

API for Point of Sale

In this section we will discuss the integration options for developers of Point Of Sale (POS) systems.
There are two main options:

1. Default: POS uses a payment terminal/pin pad (DEFAULT/Card Present scenario)
   
2. POS does NOT use a payment terminal/pin pad (Card Not Present scenario), or you have already integrated a pin pad into your system
   

→ Please, see the mini-POS developer package (download, unzip the file and run the executable, the code is in the INC directory)
