🧩 Integrations: Native n8n Support

WA-AKG natively supports n8n! You can build complex, no-code/low-code WhatsApp automation workflows using our official community nodes.

• Action Node: Full control over messaging, groups, sessions, contacts, and labels directly from your n8n workflows.
• Trigger Node: Instantly catch real-time webhooks (Message Received, Group Joined, etc.) and trigger your workflows automatically.

🚀 Quick Installation

1. Prerequisites

• Node.js 20+ (Node.js 22 recommended)
• MySQL or PostgreSQL
• Git
• PM2 (Installed globally: npm install -g pm2)

2. Setup

# Clone and install
git clone https://github.com/mrifqidaffaaditya/WA-AKG.git
cd WA-AKG
npm install

# Configure environment
cp .env.example .env
# Edit .env with your DATABASE_URL, AUTH_SECRET, PORT, etc.

# Push schema and generate Prisma Client
npm run db:push

# Create SuperAdmin account
npm run make-admin admin@example.com password123

3. Run (Development)

npm run dev

4. Run (Production with PM2 - Recommended)

We recommend deploying with PM2 to run the app in the background and ensure it restarts automatically if the server rebooted or crashed.

Option A: Automatic Setup Script (Easiest)

We provide a built-in start.sh script that automates everything: checking the configuration, installing dependencies, syncing the database schema, compiling production assets, and starting or reloading PM2:

./start.sh

Option B: Manual Setup

1. Build the application: bash npm run build

2. Start with PM2: Using the built-in ecosystem.config.js configuration file: bash pm2 start ecosystem.config.js

3. Manage the process: - View status: pm2 status - View logs: pm2 logs wa-akg - Stop process: pm2 stop wa-akg - Restart process: pm2 restart wa-akg

4. Enable auto-start on server boot: bash pm2 startup # Copy-paste the command outputted by the command above pm2 save

🐋 Alternative: Docker Deployment

Although PM2 is highly recommended, you can also deploy using Docker Compose:

1. Prepare Environment: bash cp .env.example .env Edit .env — set DATABASE_URL (points to the MySQL container), AUTH_SECRET, and other branding settings.

2. Start Services: bash docker compose up -d This spins up the MySQL database container alongside the Next.js gateway application.

📚 API Reference Overview

Example: Send Text Message

curl -X POST http://localhost:3000/api/messages/session_01/62812345678@s.whatsapp.net/send \
  -H "X-API-Key: your_api_key" \
  -H "Content-Type: application/json" \

  }'

⚠️ Known Issues / Caveats

[!WARNING] Status Update Feature (POST /api/status/update)

The WhatsApp status/story update feature is currently experiencing known issues and should be avoided in production: - Text statuses with custom background colors may not display correctly - Media statuses (images/videos) may fail to upload to WhatsApp servers - The feature is under active development

We recommend waiting for the next release before using this endpoint in critical workflows.

🛡️ Security

• API Key Auth: Secured endpoints using X-API-Key header.
• RBAC: Multi-role support (SUPERADMIN, STAFF, USER).
• Encrypted Passwords: All passwords hashed with bcrypt.
• JWT Encryption: Session tokens signed with AUTH_SECRET (wajib diisi — tidak ada fallback).
• Input Validation: Zod schemas on critical endpoints.
• Media Protection: Path traversal prevention, session-scoped media access.
