WhatsApp Chat Plugin
WhatsApp Web (Baileys) bridge for Fusion. It pairs with your phone (QR or pairing code), keeps a background connection alive, forwards inbound direct text messages to a Fusion AI session, and sends the assistant reply back to WhatsApp.
No Meta Cloud app, webhook URL, verify token, or Graph API credentials are required.
Setup
- Enable/install the plugin in Plugin Manager.
- Configure
allowedSenders(empty means nobody is allowed). - Choose
pairingMode:qr(default): fetch QR from/api/plugins/fusion-plugin-whatsapp-chat/qrand scan in WhatsApp.code: setpairingPhoneNumber(E.164 digits without+) and request code via/pair-code.
- Confirm
/statusreportsconnected.
Settings
pairingMode:qrorcode.pairingPhoneNumber: E.164 digits without+(used forcodemode).allowedSenders: allowed WhatsApp JIDs or E.164 digits.agentSystemPrompt: system prompt for replies.historyTurnLimit: persisted turn window (default40).

Storage and lifecycle
- Starts socket on
onLoad, stops ononUnload. - Persists transcript and dedupe state in:
whatsapp_chat_sessionswhatsapp_chat_dedupe
- Persists Baileys auth state in:
whatsapp_auth_credswhatsapp_auth_keys
- After restart, plugin reconnects automatically when auth is valid.
Troubleshooting
- Stuck
awaiting-qr: fetch a fresh QR and scan promptly. loggedOut: call/logout(or wait for clear) and re-pair.- Pair code not generated: ensure
pairingPhoneNumberis E.164 digits without+. - No replies: check
allowedSenders; empty list blocks all inbound messages by design.
