## Quick Start
|
||||
|
||||
1. Start the gateway (build/run your application that embeds the WebSocket gateway).
|
||||
2. Connect a client to the WebSocket endpoint:
|
||||
- URL: `ws://<host>:<port>/sync?api_key=<your_api_key>`
|
||||
3. Immediately send a handshake JSON with type `mod` or `bot`.
|
||||
4. On success, you’ll receive `{"status":"connected","type":"mod|bot"}`.
|
||||
5. Exchange messages as JSON.
|
||||
|
||||
See the full details below.

## Troubleshooting
|
||||
|
||||
### Connection Refused
|
||||
- Verify the gateway is running
|
||||
- Check the port is correct (default: 3333)
|
||||
- Ensure firewall allows connections
|
||||
|
||||
### 401 Unauthorized
|
||||
- Verify API key is correct
|
||||
- Check API key is properly URL-encoded in query string
|
||||
|
||||
### Handshake Timeout
|
||||
- Ensure handshake is sent within 60 seconds of connection
|
||||
- Verify handshake JSON is correctly formatted
|
||||
|
||||
### Messages Not Received
|
||||
- Check `channel_id` matches between mod and bot
|
||||
- Verify recipient is connected
|
||||
- Check queue status in acknowledgments
|
||||
|
||||
### Connection Drops
|
||||
- Ensure pong responses are sent to pings
|
||||
- Check network stability
|
||||
- Implement reconnection logic
