How to make an own module?

Dear zencart using friends! :smile:

I am interesting in making my own payment module but can't find info about this anywhere.

maybe it's because I'm not a native english speaker and search for wrong words...sorry if it exist such a thread already.

If there is no such guide/tutorial I would be very thankful if a helpful person could make one for all of us.

And of course am I going to publish my payment module. (it's for payson.se - a swedish paypal)

BTW I am using 1.3.8

As far as I know, there aren't any tutorials for creating payment mods.

My guess is that most are created by looking at existing payment mods to work out the Zencart part, and the payment processor's instructions/API for the rest.
