How to execute shell command or call URL on new gitlab issue? I want to execute a shell command or call a URL when a user creates a new issue. The reason behind this is to synchronize our Gitlab issues with our CalDav calendar infrastructure. We are using Gitlab community.
That's mostly what gitlab webhooks are for I think.

For your case that would be an issue event and you'll have to create something to parse the posted json and do whatever is needed on your CalDav infra to match your needs.
