💬 WhatsApp Business

Connect a WhatsApp Business account to send + receive messages from inside the unified Synalux chat surface.

📨 WhatsApp Business Cloud API

• Webhook ingress — /api/v1/whatsapp/webhook receives incoming messages, validates Meta’s signature, and surfaces them in the chat thread.
• Outbound — /api/v1/whatsapp/send posts to Meta’s Cloud API. Workspace-scoped credentials (Phone Number ID + access token).
• Templates — pre-approved message templates for transactional sends (appointment reminders, intake confirmations).
• Media — text, images, documents, audio, location pins. Audio runs through Transcription on receipt.

🔐 Setup

1. Create a Meta Business + WhatsApp Business app at business.facebook.com .
2. Generate a permanent System User access token; paste into Synalux workspace settings.
3. Configure webhook URL https://synalux.ai/api/v1/whatsapp/webhook with your verify token.
4. Subscribe to messages + message_status events.

The in-app setup guide modal (/chat) walks you through every step with the exact field names from the Meta dashboard.

🏗️ Architecture

POST /api/v1/whatsapp/webhook     Meta webhook ingress (signature-validated)
POST /api/v1/whatsapp/send         Outbound (template or freeform within 24h window)
GET  /api/v1/whatsapp/templates    List approved templates for the workspace

Provider abstraction: lib/message-providers/whatsapp.ts matches the generic shape (Gmail / Telegram / SMS / etc.).

⚖️ HIPAA + Compliance

WhatsApp’s terms restrict PHI for non-Meta-BAA accounts. Synalux flags any message that looks PHI-bearing and requires explicit workspace-admin opt-in to send via WhatsApp. Signed BAA with Meta is on the customer’s roadmap.
