Realtime WebSocket Alert Relay
Use Heym as a lightweight relay between two realtime systems. This template listens to an external socket feed, filters for critical alerts, logs the forwarded payload, and republishes it to another WebSocket endpoint.
What this workflow does
- Sticky Note documents the expected payload shape on the canvas
- WebSocket Trigger subscribes to an external event stream
- Condition filters for critical JSON alerts only
- Console Log writes the forwarded alert to backend logs
- WebSocket Send republishes the alert to a downstream fanout channel
- Non-critical events fall through to Output for lightweight run tracking
Use cases
- Operations alert fanout
- Telemetry bridge between internal systems
- Realtime event normalization before downstream processing
Setup
Set the upstream and downstream WebSocket URLs to your own services. If the remote sockets require auth, add handshake headers in the trigger and send nodes.
