Webhooks, how do they work?

Would someone mind explaining to me how they work? In the simplest form obviously, I don’t expect a full tutorial :slight_smile:

For example Owntracks can now use them but I don’t understand how it can communicate with a 192.168.x.x address?

I once posted an example here. It’s an exercise for you to figure out how that can be used for your specific usecase. :wink:
