Multi-Device Management

Manage unlimited WhatsApp and Telegram devices from one dashboard

Device Connection Benefits

  • ✓ Connect multiple WhatsApp and Telegram devices to a single API gateway
  • ✓ Each device gets independent session management and status monitoring
  • ✓ Automatic session persistence — sessions survive server restarts
  • ✓ Round-robin message distribution across multiple devices for higher throughput
  • ✓ Real-time connection status monitoring with automatic alerts

Device Configuration

// Device Configuration (per device) { "device_id": "wa_001", "type": "whatsapp", "status": "connected", "last_active": "2025-01-15T10:30:00Z" }

Configure and manage devices from the dashboard or API. Net2APP's OTT Worker maintains persistent WebSocket connections for WhatsApp (Baileys) and MTProto connections for Telegram with automatic reconnection.

💡 Tip: Use multiple devices with round-robin distribution for high-volume messaging while maintaining account health across all connected devices.

WhatsApp & Telegram API — FAQ

Common questions about the Business API

Do I need a business verification for WhatsApp API?▼

Net2APP uses the Baileys library which implements the WhatsApp Web protocol — the same method used by WhatsApp Web and the desktop app. You do NOT need WhatsApp Business API approval or a verified business account. Any WhatsApp account can be connected via QR code pairing.

What are the advantages of MTProto over Telegram Bot API?▼

MTProto (used by the Telegram mobile/desktop app) offers: (1) Higher rate limits — send more messages per second. (2) Message any phone number, not just users who started a chat with a bot. (3) Full media support including all file types. (4) Access to your personal contacts and groups. The Bot API has stricter limits and limited functionality.

Can I use both WhatsApp and Telegram with the same API key?▼

Yes. The Net2APP Business API uses a single tenant API key for both WhatsApp and Telegram endpoints. You specify the device_id in the API request to select which paired device to send from. This allows unified API integration for both messaging platforms.

How does the OTT Worker maintain connections?▼

The OTT Worker is a background Node.js process (src/workers/ott-worker.ts) that maintains persistent WebSocket connections for each paired device. It handles: automatic reconnection on disconnection with exponential backoff, session persistence to database, media download for incoming messages, and keep-alive pings to detect connection drops.

Is there a limit on how many messages I can send?▼

Message rates are limited per device to maintain account health. Default rate limits are configurable from the dashboard. For high-volume WhatsApp messaging, we recommend using multiple paired devices with round-robin message distribution for optimal throughput.
