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. - For more command `./whatsapp --help` ## Requirements ### System Requirements - **Go 1.24.0 or higher** (for building from source) - **FFmpeg** (for media processing) ### Platform Support - Linux (x86_64, ARM64) - macOS (Intel, Apple Silicon) - Windows (x86_64) - WSL recommended ### Dependencies (without docker) - Mac OS: - `brew install ffmpeg` - `export CGO_CFLAGS_ALLOW="-Xpreprocessor"` - Linux: - `sudo apt update` - `sudo apt install ffmpeg` - Windows (not recomended, prefer using [WSL](https://docs.microsoft.com/en-us/windows/wsl/install)): - install ffmpeg, [download here](https://www.ffmpeg.org/download.html#build-windows) - add to ffmpeg to [environment variable](https://www.google.com/search?q=windows+add+to+environment+path) ## How to use ### Basic 1.

Clone this repo `git clone https://github.com/aldinokemal/go-whatsapp-web-multidevice` 2. Open the folder that was cloned via cmd/terminal. 3. run `cd src` 4. run `go run . mcp` or build the binary and run `./whatsapp mcp` 5. The MCP server will start on `http://localhost:8080` by default #### MCP Server Options - `--host localhost` - Set the host for MCP server (default: localhost) - `--port 8080` - Set the port for MCP server (default: 8080) #### Available MCP Tools - `whatsapp_send_text` - Send text messages - `whatsapp_send_contact` - Send contact cards - `whatsapp_send_link` - Send links with captions - `whatsapp_send_location` - Send location coordinates #### MCP Endpoints - SSE endpoint: `http://localhost:8080/sse` - Message endpoint: `http://localhost:8080/message` ### MCP Configuration Make sure you have the MCP server running: `./whatsapp mcp` For AI tools that support MCP with SSE (like Cursor), add this configuration: ```json { "mcpServers": { "whatsapp": { "url": "http://localhost:8080/sse" } } }
