How to identify unknown webhook calls

Hi,

I keep getting entries in my log about unknown calls to a webhook. I cannot figure out where they’re coming from. From the IP-address it looks like it is a Docker container making the calls? But how do I identify which?

I would appreciate any help / hints.

Thanks.

Here’s a log entry example:

Logger: homeassistant.components.webhook
Source: components/webhook/init.py:84
