Http Api command to Zennio Getface IP

[Evens]

Hi,
 
On a project I’m working on, we have a kNX switch that shall open a lock, in the main door of a house. The video intercom device is a Zennio Getface IP. I want to use the LM5 lite that I already have, to be used as a gateway. To my knowledge the Zennio Getface Ip has Http Api license installed.

Is it possible to do? And if so can someone help me?
LM5 ip:                                 192.168.1.103
Zennio Getface ip:           192.168.1.101   
 
See link below for manual to Zennio Getface IP:
