Matlab connection - GET Syntax

[Pinky und Brain]

Hi Phyphoxer

I use Phyphox in my physicx-Class. Since i grew up with Matlab, i would like to connect PhyPhox with matlab. 
The remote interface is working fine, the communication can't be very hard since matlab has functions for JSON. I have no experience with that protocol, hence i have problems understanding the syntax of the GET? command.
In the WIKI there is a example 

/get?abc

I just want to poll the lates sensordata for e.g. acceleration sensor. I don't understand what "abc" means and how to change the syntax to address the buffer for the accelleration sensors.

Thank you for your Help
