I'm trying to implement in app purchases and subscription management on the server depends on properties like a unique subscription_id and any changes to auto_renew_status with each notification. the docs say this information should be present in a notification body but when i get sandboxed response they are missing any potentially identifying top level properties (such as an auto_renew_adam_id if i understand that property correctly.)
do i use the auto_renew_adam_id to identify a subscription? if so how do i go about testing it in the sandbox, or at all?
