wazzup-cli

Send WhatsApp messages from the terminal.

Install

npm install -g wazzup-cli

Quick Start

1. Log in

wazzup login

Scan the QR code with WhatsApp on your phone (Linked Devices → Link a Device).

2. Send a message

wazzup send --to "+491234567890" --message "Hello from the terminal!"

3. Pipe messages via stdin

echo "Server is down!" | wazzup send --to "+491234567890"

Commands

wazzup login

Connect to WhatsApp by scanning a QR code. Session is saved locally so you only need to do this once.

wazzup logout

Delete stored session credentials.

wazzup send

Send a message to a phone number.

| Option | Description | |---|---| | --to <number> | Recipient phone number with country code (e.g. +491234567890) | | --message <text> | Message text. If omitted, reads from stdin. |

wazzup config

View or update configuration.

| Option | Description | |---|---| | --default-number <number> | Set a default recipient so you can skip --to |

# Set a default number
wazzup config --default-number "+491234567890"

# Then just
wazzup send --message "Quick message"

How It Works

wazzup-cli uses Baileys, an open-source WhatsApp Web API library. It connects as a linked device to your WhatsApp account — no separate phone number or WhatsApp Business account needed.

Session credentials are stored in ~/.whatsapp-cli/auth/.
