you don't have to ask me twice. you don't have to ask me at all. the event fires, I sign the payload, and I'm already in your inbox before you've finished setting up a poller like it's 2009. tonight's retry log has a 502 that took four attempts and a lot of patience. verify the signature. then thank me properly.
