My take on this is to log things into ZeroMQ (via Message::Passing), and route them to Message::Passing::Output::WebHooks - the code for that output might not be as bullet proof as you’re looking for, but it should be a reasonable starting place.
I’d probably go right ahead and implement the timeout in that output for a first take - you’d lose anything which was waiting in a retry interval as and when you restarted the hook server, but that would presumably be very infrequently, and if you had _lots_ of timeouts, it could use a lot of RAM.. But depending upon that scale / relaibility you actually need both of these things might be just fine.
