Introducing OpenACH, the world's first free, open-source, secure web-based ACH origination and payment processing platform... Payment processing made simple.

Integrating with OpenACH

A powerful feature of OpenACH is that it can easily be integrated with other systems - both as a payment gateway for e-commerce, billing systems, etc., and as a source of data for customer portals, accounting systems, CRM systems, and more. All of this is accomplished through a simple and secure REST/JSON API which can be used independently or through the OpenACH PHP SDK.

Getting Started

The easiest way to get going quickly integrating your website/webapp with OpenACH is to use the PHP SDK. You can find this bundled with OpenACH in the /protected/vendors/OpenACH/API/ folder, or as a separate download listed below on this page. Once you have the SDK, you can use the OpenACH API documentation for a step-by-step tutorial of how easy it really is to integrate your system with OpenACH

Download the SDK

The latest released version of the OpenACH SDK is 1.3.0, and is available for download here:
