OpenACH Developer Guide

Welcome to the OpenACH Developer Guide. If you are a developer, systems integrator, systems architect, server administrator, or even just interested in the technology behind the OpenACH platform, this guide is for you. It covers topics such as basic structure of the application, how the code is organized, how to extend the system, and how to integrate other websites/webapps with OpenACH to use it as a payment gateway and/or allow your customers to see their payment schedules. This guide assumes you have a basic understanding of what OpenACH is and how it is used to process payments. If you are at all unclear on these basics, first refer to the OpenACH User Guide.

This guide is broken into three major sections:

The OpenACH Framework

Integrating with OpenACH

Describes how to use the OpenACH SDK to integrate a website/webapp with the OpenACH platform.

The OpenACH Database
