It seams a bit odd, but reading other requests on this i still find it hard to believe that there is absolutely no way to dynamically change an authorization token for a WebSocket, just want to make sure is this right? [image]

Ah, interesting! Never noticed that before. Clearly nobody else has ever bothered either. Of course, the header is only available on the initial handshake for ws connections so an authorization header is of very limited use.

That screenshot is not of the built in node.

Doh! I was looking at the out node (where I expected this to be!)

No worries, took me several attempts to find it. I guess neither of us really use that node. :rofl:

BTW, just seen my reply here: [image] Setting Websocket Headers dynamically General So I think you will need to do something like watching for the connection error, using a catch node, using that to trigger a flow to regen the token which you capture to a flow context var…

if this limitation, not being able to dynamically set an authorization header like a token which by definition expires, then i am not surprised why not many use it.... seems useless for those cases where you need to authenticate to start a WebSocket connection... or am i missing something?

if the solution ends with "create your own node" :smiley: :smiley: then.... i really question, why is it not a feature in the common / out of the box node.

You can always try a contrib node: Library - Node-RED

No you aren't missing anything. Raw websockets are of limited use in terms of security. You can authorise the initial handshake using a header (don't forget that you also need to use WSS: not WS: - e.g. you need a TLS secured connection) but then you cannot have a timed session. Which means that onc…
