dont know.

I Try to get some data from the web socket using Postman.

If I use the Cumulocity Collection and send POST [
{
“version”:“1.0”,
“minimumVersion”:“0.9”,
“channel”:“/meta/handshake”,
“supportedConnectionTypes”:[“long-polling”],
“advice”:{
“timeout”:60000,“interval”:0
}
}
]
to my {{url}}/notification/realtime

its working fine. I get the client ID and can subcribe to a channel.

When i try to start a Wesocket Connection like that tutorial:
`Postman Now Supports WebSocket APIs | Postman Blog

i get the error 403::Handshake denied

[{“channel”:“/meta/handshake”,“error”:“403::Handshake denied”,“data”:null,“advice”:{“reconnect”:“none”},“successful”:false}]

Thanks for help.
