New backend. How to connect?

I was using the REST API to get the JSON data to my application but want to go for the new backend.
My node data is currently accumulated here
http://thethingsnetwork.org/api/v0/nodes/05060708/

I am going through the tutorial to get connected to my node data,
but here it says that I use

Uplink
Path: /devices//up (use +/devices/+/up to get data from all devices)

to connect to the TTN with my device eui. Can somone explain`me how and what it means. I cannot see anything with
http://thethingsnetwork.org/devices/05060708/

Thanks in advance.
