This is the second in a series of postings on how to integrate credit card and ACH/E-check transactions into various systems. This installment demonstrates code used for processing payments (credit card and/or ACH) within a 4D (4th Dimension) application.

This was taken from the NELiX TransaX FleXport toolkit documentation. Credit card integration examples can be downloaded on the NELiX TransaX FleXport page.

Assumptions:
- Using NELiX TransaX Payment Gateway
- Communicating using NELiX TransaX Webservice

It's simple. You are a software developer. Integrate payment processing into your applications on behalf of your customers, and earn money!

Merchant account providers, for the most part, understand that people need to process payments online. However, they don't understand technology as a whole, and how it's used in the market place.

Developers, for the most part, understand that they may need to integrate some form of payment collecting into an application they are developing, but they don't understand, for the most part, the merchant account industry.

The result of this is a lot of business left on the table. Many developers will go out and find partners, when their customer asks them to add a credit card processing piece to their system. The developer will go out, find some component somewhere, plug it in, bill for their development hours, and be done with it.

We at NELiX TransaX have the answer!

It has been a long time since I've blogged. I've been spending my time managing projects.

50% of my time has been managing integration projects - where we are integrating our credit card and ACH/e-check processing components into existing systems on our customers behalf.

The other 50% of my time has been spent on managing projects where we are building completely new systems to manage our customers payment processing functions.

The final 50% of my time has been spent on everything else :-)

On the integration projects, we have been using our FleXport library to integrate credit card processing into a wide variety of applications. We've had a lot of ASP, .NET, Access and FileMaker integrations lately. We've also been integrating credit card and ACH processing into many VB6 systems lately, surprisingly. We'll be adding a FleXport example for VB6 very soon!

In addition, we've spent a lot of time supporting partners who are integration our payment processing componen…
