# GOWA - WhatsApp Automation via REST API

Interact with WhatsApp through GOWA (Go WhatsApp Web Multi-Device) REST API for personal automation tasks.

## Installation & Setup

GOWA is available at: https://github.com/aldinokemal/go-whatsapp-web-multidevice

### Download

Go to the [releases page](https://github.com/aldinokemal/go-whatsapp-web-multidevice/releases) and download the zip matching your OS and architecture.

Release files are named: `whatsapp_VERSION_OS_ARCH.zip`

Available platforms: `linux` (amd64/arm64/386), `darwin` (amd64/arm64), `windows` (amd64/386)

### Run REST Server

```bash
./gowa rest
```

The server starts on `http://localhost:3000` by default.

### Login (First Time)

Open `http://localhost:3000` in a browser, scan the QR code with WhatsApp on your phone to link the device.

## Production Setup

**GOWA runs in REST mode:**
- Base URL: `http://localhost:3000`
- GOWA auto-connects to the device stored in the database — no `X-Device-Id` header needed for single-device setups.

**⚠️ Important:** Use REST API (port 3000) only. Do NOT use MCP mode - all schedulers and automation depend on REST.

## Quick Examples

### Ghost Mention (mention all without @)
```bash
curl -X POST http://localhost:3000/send/message 
  -H "Content-Type: application/json" 
  -d '{
    "phone": "120363040656010581@g.us",
    "message": "Important announcement",
    "mentions": ["@everyone"]
  }'
```

### Send Text Message
```bash
curl -X POST http://localhost:3000/send/message 
  -H "Content-Type: application/json" 
  -d '{"phone": "628123456789", "message": "Hello!"}'
```

### Send Image
```bash
curl -X POST http://localhost:3000/send/image 
  -F "phone=628xxx" 
  -F "caption=Photo" 
  -F "image=@/path/to/image.jpg"
```

### Check Status
```bash
curl http://localhost:3000/app/status | jq .
```
