Would be cool if Transloadit signed the POST notification with the private key so the recipient can validate the authenticity and integrity of the message.
Konstantin, I think you could just create your own by adding a signature of some sort into the “fields” and then verifying it when the notification comes in.
for now you can add a random callback in the URL to verify the message. We know that is not a perfect solution and we have this definitely in our todo list.
