REST API Notifications Help

Hi!

I have a problem with API notification. I dont understand how it works. I can subscribe my url to volumio…I see that the volumio got it, but how to use it? This url is link to a file or what? I want to send it to home automation system. In wireshark I see this frames, but how to get it in my purpose :slight_smile:

Thank you.
