Hello everyone,

I am a new Zen Cart user and I would like to know how to create my own
payment module. If anyone has a quick link to a good post or page where
I can find trustworthy information it would be greatly appreciated.

I need to create a module to support Concorde EFS as a payment gateway.
I have full documentation on their system, so I'm good there I hope. I am
'fluent' in PHP, Perl, and more. I think I have the experience and knowledge
to pull it off, I just don't know where to start.

If I actually get this to work (properly and securely) I'll post it on the forum
for others to make use of just in case they get stuck with this lovely no-name
half-rate merchant.

With best regards,
Mike
