Enables sending WhatsApp messages, images, videos, files, audio, contacts, links, locations, and polls. Supports group management, user operations, message reactions, and webhook notifications for received messages.

1. Click on "Install Server".

2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@WhatsApp Go MCP send a message to John Doe saying 'Meeting at 3 PM tomorrow'"

That's it! The server will respond to your query, and you can continue using it as needed.

Here is a step-by-step guide with screenshots.

## Support for `ARM` & `AMD` Architecture along with `MCP` Support

Download:

- [Release](https://github.com/aldinokemal/go-whatsapp-web-multidevice/releases/latest)
- [Docker Hub](https://hub.docker.com/r/aldinokemal2104/go-whatsapp-web-multidevice/tags)
- [GitHub Container Registry](https://github.com/aldinokemal/go-whatsapp-web-multidevice/pkgs/container/go-whatsapp-web-multidevice)

## Support n8n package (n8n.io)

- [n8n package](https://www.npmjs.com/package/@aldinokemal2104/n8n-nodes-gowa)
- Go to Settings -> Community Nodes -> Input `@aldinokemal2104/n8n-nodes-gowa` -> Install

## Breaking Changes

- `v6`
 - For REST mode, you need to run `<binary> rest` instead of `<binary>`
 - for example: `./whatsapp rest` instead of ~~./whatsapp~~
 - For MCP mode, you need to run `<binary> mcp`
 - for example: `./whatsapp mcp`
- `v7`
 - Starting version 7.x we are using goreleaser to build the binary, so you can download the binary
 from [release](https://github.com/aldinokemal/go-whatsapp-web-multidevice/releases/latest)

## Feature

- Send WhatsApp message via http API, [docs/openapi.yml](./docs/openapi.yaml) for more details
- **MCP (Model Context Protocol) Server Support** - Integrate with AI agents and tools using standardized protocol
- Mention someone
 - `@phoneNumber`
 - example: `Hello @628974812XXXX, @628974812XXXX`
- Post Whatsapp Status
- Compress image before send
- Compress video before send
- Change OS name become your app (it's the device name when connect via mobile)
 - `--os=Chrome` or `--os=MyApplication`
- Basic Auth (able to add multi credentials)
 - `--basic-auth=kemal:secret,toni:password,userName:secretPassword`, or you can simplify
 - `-b=kemal:secret,toni:password,userName:secretPassword`
- Subpath deployment support
 - `--base-path="/gowa"` (allows deployment under a specific path like `/gowa/sub/path`)
- Customizable port and debug mode
 - `--port 8000`
 - `--debug true`
- Auto reply message
 - `--autoreply="Don't reply this message"`
- Auto mark read incoming messages
 - `--auto-mark-read=true` (automatically marks incoming messages as read)
- Webhook for received message
 - `--webhook="http://yourwebhook.site/handler"`, or you can simplify
 - `-w="http://yourwebhook.site/handler"`
 - for more detail, see [Webhook Payload Documentation](./docs/webhook-payload.md)
- Webhook Secret
 Our webhook will be sent to you with an HMAC header and a sha256 default key `secret`.

 You may modify this by using the option below:
 - `--webhook-secret="secret"`
- **Webhook Payload Documentation**
 For detailed webhook payload schemas, security implementation, and integration examples,
 see [Webhook Payload Documentation](./docs/webhook-payload.md)

## Configuration

You can configure the application using either command-line flags (shown above) or environment variables. Configuration
can be set in three ways (in order of priority):

1. Command-line flags (highest priority)
2. Environment variables
3. `.env` file (lowest priority)

### Environment Variables

You can configure the application using environment variables. Configuration can be set in three ways (in order of
priority):

1. Command-line flags (highest priority)
2. Environment variables
3. `.env` file (lowest priority)

To use environment variables:

1. Copy `.env.example` to `.env` in your project root (`cp src/.env.example src/.env`)
2. Modify the values in `.env` according to your needs
3. Or set the same variables as system environment variables

#### Available Environment Variables

| Variable | Description | Default | Example |
|-------------------------------|---------------------------------------------|----------------------------------------------|---------------------------------------------|
| `APP_PORT` | Application port | `3000` | `APP_PORT=8080` |
| `APP_DEBUG` | Enable debug logging | `false` | `APP_DEBUG=true` |
| `APP_OS` | OS name (device name in WhatsApp) | `Chrome` | `APP_OS=MyApp` |
| `APP_BASIC_AUTH` | Basic authentication credentials | - | `APP_BASIC_AUTH=user1:pass1,user2:pass2` |
| `APP_BASE_PATH` | Base path for subpath deployment | - | `APP_BASE_PATH=/gowa` |
| `DB_URI` | Database connection URI | `file:storages/whatsapp.db?_foreign_keys=on` | `DB_URI=postgres://user:pass@host/db` |
| `WHATSAPP_AUTO_REPLY` | Auto-reply message | - | `WHATSAPP_AUTO_REPLY="Auto reply message"` |
| `WHATSAPP_AUTO_MARK_READ` | Auto-mark incoming messages as read | `false` | `WHATSAPP_AUTO_MARK_READ=true` |
| `WHATSAPP_WEBHOOK` | Webhook URL(s) for events (comma-separated) | - | `WHATSAPP_WEBHOOK=https://webhook.site/xxx` |
| `WHATSAPP_WEBHOOK_SECRET` | Webhook secret for validation | `secret` | `WHATSAPP_WEBHOOK_SECRET=super-secret-key` |
| `WHATSAPP_ACCOUNT_VALIDATION` | Enable account validation | `true` | `WHATSAPP_ACCOUNT_VALIDATION=false` |
| `WHATSAPP_CHAT_STORAGE` | Enable chat storage | `true` | `WHATSAPP_CHAT_STORAGE=false` |

Note: Command-line flags will override any values set in environment variables or `.env` file.
