WebSocket Close Codes

Reference for all WebSocket close codes returned by the TikTool API.

Close Codes

When a WebSocket connection closes, it includes a numeric code and a reason string.

Standard Codes

Code	Name	Description
1000	Normal Closure	Clean disconnect — stream ended or you closed the connection
1001	Going Away	Server shutting down or stream ended
1006	Abnormal Closure	Connection dropped without a close frame (network issue)
1008	Policy Violation	Violated rate limits or usage policy
1011	Internal Error	Server-side error — reconnect with backoff

TikTool Custom Codes

Code	Name	Description
4000	Stream Offline	The TikTok user is not currently live
4001	Stream Ended	The live stream ended while you were connected
4002	Rate Limited	Too many connections — wait and retry
4003	Authentication Failed	Invalid API key or expired JWT token
4004	User Not Found	The TikTok username doesn’t exist
4005	Tier Limit	Connection limit reached for your tier
4006	Duration Limit	Maximum connection duration reached (Sandbox: 5 min, Basic: 30 min)
4007	Server Overloaded	Server at capacity — retry with exponential backoff

Handling Close Codes

ws.on('close', (code, reason) => {
  const reasonStr = reason.toString();

  switch (code) {
    case 4000:
    case 4001:
      console.log('Stream offline/ended — stop reconnecting');
      break;
    case 4003:
      console.error('Auth failed — check your API key');
      break;
    case 4005:
    case 4006:
      console.warn('Tier limit — upgrade your plan');
      break;
    default:
      // Reconnect with exponential backoff
      setTimeout(connect, reconnectDelay);
      reconnectDelay = Math.min(reconnectDelay * 2, 30000);
  }
});

Don’t reconnect on codes 4000, 4001, 4003, or 4004 — these indicate permanent conditions that won’t change on retry.
