## 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

  - `--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"`

- 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
