So I'm using Authorize.net to charge monthly/yearly subscriptions that recur automatically. When I changed the price of two products (to $4.95 and $49.95 down from $5.95 and $59.95), the customers keep getting charged at the old amount. I thought that since the rebill request comes from aMember (the CC information is store with Authorize) it will simply pick up the new price when it comes time to send the transaction again to the payment processor. Any idea how to fix this? Or how to bulk-update the existing customers to the new price? Cheers!
This is expected. User's subscription terms are stored in invoice record so product modifications won't affect current recurring subscriptions. You need to alter terms in database directly in am_invocie table.
I had this issue with PayPal Pro and the guys made me a nice plugin that updates everyone en-mass, sends everyone an email to tell them about the change and records everything in a log file. Might be worth asking them for something similar.
