Use silent post to record each transaction in your database as it comes in. Probably by matching on customer ID. Short of that, you can use the Transaction Details API to look up all settled transactions and record them in your database. Either way, you're going to want to record transactions on your end so you can look them up later, since Authorize.net has no way to just pass a subscription ID and get all transactions for that subscription.
