How do you refund a transaction in Authorize.net?

Question

I am just referring the docs of Authorize.net. I will soon be working on a Automated Recurring Billing application. The code seems to be pretty simple for this as the doc is very well written. However in the samples I can't find how to refund the transaction.

This is the link that I am referring to:

Any help would be appreciated. Thanks in advance :)

You can't do refunds with the ARB API. It must be done either through the AIM API or the merchant control panel. If you use AIM set x_type to CREDIT instead of AUTH_CAPTURE .
