Proxmox api vncwebsocket

Hey guys :),

I am currently trying to embed a console into a website.
from what I read to this point the way to do it is :
POST /api2/json/nodes/{node}/qemu/{vmid}/vncproxy
GET /api2/json/nodes/{node}/qemu/{vmid}/vncwebsocket
- vncticket = ticket from previous request ; port = port from previous request

The first part works just fine.(I get a ticket in following format : PVEVNC:xxxxxxxx==)
The second part is where stuff breaks for me. To this point I got a 401 - invalid PVEVNC ticket any time I tried it.

Another thing I read about was adding websocket = 1 to the first request.
That didn't change anything in my case either.

I would be very happy for some ideas on how to fix it!;)

the ticket for vnc has to be used within 40 seconds. If you tried things manually, might you have taken longer? Otherwise, is the parameter properly URL-encoded in the request URL?
