I added credit card refunds to the authorize.net cim module by doing a form_alter on uc_payment_by_order_form to provide a "refund" link for each payment made on an order. A successful refund enters a negative value in the payment table. It seems to work well enough (though I just saw there's a typo I need to correct!)

Let me know if you see any ways to improve this.

Best,

I implemented refunds by just passing a negative amount and handling it accordingly in the moneris module. Once I added refunds I realized I need to have charges afterwards as well. So I change the payment processes to support passing an operation, so you could pass charge, complete, refund, void etc. That worked fine as well, the problem is I need the full credit card number to do a new charge but only the last 4 digits are available. I believe you can store the full number as long as it is encrypted (which it is) and still be PCI compliant. Is in not stored at all or do I just not know how to retrieve it?

Thanks in advance

sorry neglecting my posts, I did some changes to the moneris module but also to the uc_credit and uc_payment to make refunds a little nicer than just entering a negative number. I will gladly post the code once it passes QA here at work although I've been talking to Ryan and hopefully we can make some changes to ubercart to be a lot more friendly to different types of transactions like refunds, voids etc.

Hmm... with the improvements to the CC API in 1.6, I imagine implementing refunds should be a little easier. I defined credits as a transaction type, but I'm not sure if I made a specific button for them on the credit card terminal form.
