Thats fine, thanks for the quick answer. If I can get the time to do the mod before others get to it, who should I pass the module to for review and inclusion? Doc Byte, NetworkDad, or should I just post a url to it and let whoever needs it do what they wish?

Do you have any pointers for what function names to add to the module for the refund process, or should I just have a look at the paypal module? I have worked very extensively with AuthNet in many of my proprietary Windows/Linux apps, so the data formatting/handling back and forth isn't a problem, just need to know what the names are for the refund related functions.

I'll go ahead and try diving into the code, but will certainly appreciate in heads up you can give for those function names.

Many thanks for the awesome work all of you ZC devs do!!!!
