I am trying to work with your REST API that I read about here:  https://www.manageengine.com/network-configuration-manager/restapi.html

When I try to send a simple GET_DEVICE request for a known good IP address, I just get a blank response with HTTP 200. I expected to at least get an empty JSON response.

I'm sending in following parameters per the documentation. 

"API_KEY=123456abc&IP_ADDRESS=1.1.1.1&ACTION=GET_DEVICE"

I've tried sending these as both a GET and POST request but get same result. A blank response. 

So for example if I send a get request like this:

https://myserver.com/api/API_KEY=123456abc&IP_ADDRESS=1.1.1.1&ACTION=GET_DEVICE

I get nothing back.

Please point me to any additional examples and or documentation you have or can provide, or provide me an example URL that I can use to confirm my access to the API with my generated api_key. I would be very grateful. Thank you advance.
