Wow! yeah I am not sure what to make of that either.
Sounds like some crazy stuff.
Postman should be able to do what you need for making the API calls. As for monitoring the network and viewing the calls that would be out of my league.
Happy to help you get some of these calls going though. I assume when you issue some of these calls via API that you can see some sort of response from the ECHO360 or see a change if you have access to it?
