In pins 4 + flow

flow
channels array required
Hidden when other fields are filled
channel value required
Hidden when other fields are filled
events array
The events to unsubscribe from. If you owuld like to unsubscribe from all events within this channel, leave this array empty or provide * as one of the values.
Default ["*"]
skip jwt condition required
Skips the broadcast of subscriptions to the frontend. If set to true, the frontend will not be able to resubscribe on the channels where the broadcast was skipped.
Default false

Out pins 3 + flow

flow
success condition
error value
channels array

Unsubscribes the current WebSocket connection from the given channels (channels array and channel pin merged, duplicates removed); the channels out pin lists the channels actually unsubscribed. Scoped to the events list when wired, all events when empty. success=false with error MISSING_CHANNELS when no channel resolves or MISSNG_WEBSOCKET (sic) when there is no connection; does nothing in simulation. Unless skipjwt is true, the new subscription set is broadcast to the frontend.

A typical wiring for unsubscribe websocket: a function trigger starts the flow; with values feeds the channels pin; value feeds the channel pin; the flow out pin feeds debug.
