Send a message from VRChat to Discord using webhooks! Simply paste a webhook from a Discord server you have webhook permissions into the script and it will construct an analytics GameObject for you.
Supports three identification modes: Anonymous, Hashed IP, and IP Address.
Eventually I'll post a GitHub repo with the server code I used to make this, but for now, feel free to use it in your VRChat worlds (or even other Unity projects).
