Recently I tried to refund some fraudulent purchases in the website I work on, so I get the paypal transaction ids we stored in our database, and ran a script to refund them all, but many of them returned as not found, apparently, they doesn't exist, but their ID's does look a lot as a real paypal transaction ID, is there a reason for paypal to return not found for a transaction other than it being not existent? We also have subscriptions, and many transactions comes from subscriptions.
Thanks.
