First let me make sure I understand how this pluggin is supposed to function. My assumption is that once you enter your credit card information, it will be stored in the Authorize.net CIM system and linked to the customers ID in Zen so that when they sign back in to place future orders the customer can choose to pay with the card on file.

I've installed this plugin on zen version 1.3.9h combined with an authorize developer test account. I've changed the url to point to https://test.authorize.net/gateway/transact.dll . From what I can tell, most everything processes correctly. The only issue i see is that the credit cards are not being stored so that, upon logging back in to place future orders, you can select the card on file.

What might I be missing?

Thanks
