Hi there.

I'm using Zen Cart on a site selling virtual products. I was hoping someone more familiar with it could tell me where is the best place to insert a custom line of code so that we can do some custom stuff we need to do after the order is complete?

We are trying not to disturb the Zen Cart codebase at all, but maybe we will have to in order to send out our customer's registration numbers, which are generated by our own custom script.

Any insights?
