I'm using the Paypal "Subscription" button. I have an IPN handler and overall I think I've got it all figured out. My last problem is that apparently there's no good way to test a recurring payment (except to wait for the cycle to occur). This issue is discussed here: [question]: Testing Paypal subscription IPN
I don't really need to test this recurring payment but I do need to know if every recurring payment will have it's own txn_id or if every payment in a subscription shares the same ID.
Thanks!
Yes, each recurring payment cycle will create a new transaction with its own transaction ID. You'd link these transactions together via their recurring payments profile ID.
