WhatsApp Integration Plugin

Communicate with Agent Zero via WhatsApp using a Baileys-based Node.js bridge.

Requirements

Node.js (v18+) and npm installed on the system
A WhatsApp account on a phone (for QR code pairing)

Setup

Install bridge dependencies

bash

cd plugins/_whatsapp_integration/whatsapp-bridge
npm install --production

Dependencies are auto-installed on first bridge start if missing.

Configure and pair

Enable the plugin in Settings > External > WhatsApp Integration
Configure allowed phone numbers
Click Show QR Code and scan with WhatsApp on your phone
Send a message from an allowed number to start a chat
Use /project <name>, /config <preset>, or /send in WhatsApp to control the active chat directly

The WhatsApp session persists across restarts in tmp/whatsapp/session/. No re-pairing needed unless you disconnect via settings. Be careful: if you use your personal number and leave allowed_numbers open, other people could misuse your Agent Zero.

Configuration

Setting	Description	Default
`enabled`	Enable bridge and polling	`false`
`mode`	`self-chat` (personal number) or `dedicated` (separate number)	`self-chat`
`allow_group`	Respond in group chats when mentioned or replied to	`false`
`bridge_port`	Local HTTP port for bridge	`3100`
`poll_interval_seconds`	Poll frequency (min 2)	`3`
`allowed_numbers`	Phone numbers without + prefix	`[]` (all)
`project`	Activate project for WA chats	`""`
`agent_instructions`	Extra agent instructions	`""`

How It Works

The bridge connects to WhatsApp via Baileys and exposes HTTP endpoints on localhost
In personal-number mode, you can message your own WhatsApp number to talk to the agent, and the agent can also handle messages that other people send to that number
The plugin polls the bridge for new messages every few seconds
Incoming messages are routed to existing chats by WhatsApp chat ID or new chats are created
Agent responses are sent back via the bridge as WhatsApp messages
Media (images, documents) is supported in both directions
