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 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

./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.

curl -X POST http://localhost:3000/send/message \

Send Image

curl -X POST http://localhost:3000/send/image \
