I'm trying to make a heavy client myself with http API (z-Way http API).
I began with that this http post wih basic authentification request (username/pass)
No luck :
HTTP/1.1 403 Forbidden
When I send JSON structure, I got
HTTP/1.1 500 Server Error
I definetly done something bad

Someone have a simple exemple of a such client written in c++/.Net/Delphi or what ever ? With detailled authentification process ?
I'm on the last RazBerry with standart z-Way image installation.
Thanks,
Vinz
