Redmine

I'd like to let Redmine call an external hook when there is any kind of activity / update on any issue: something like calling a web hook over http or running a command locally on the Redmine server.

I do know that I could poll the API at regular intervals and filter issues on updated_on but I'd really prefer for Redmine to "push" such events to an external hook.

I tried researching the topic but couldn't find such feature in Redmine nor in any published plugin... is there any way to achieve such behavior which I'm not aware of?

Any help would be appreciated, thanks!
