Audio Transcription (Optional)

For audio transcription, you need:

• ffmpeg: For audio format conversion

  • macOS: brew install ffmpeg
  • Ubuntu/Debian: sudo apt-get install ffmpeg
  • Fedora: sudo dnf install ffmpeg

• Groq API Key: Set GROQ_AUDIO_API_KEY or GROQ_API_KEY environment variable

Quick Start

1. Install Dependencies

pip install agntrick-whatsapp

2. Create Configuration

Create a whatsapp.yaml configuration file:

# Agent model configuration
model: "glm-4.7"

# Channel configuration
channel:
  storage_path: "./storage"

# Privacy and filtering - only allow your own number
privacy:
  allowed_contact: "+12 6XX X6X XX6"  # Your phone number

# Feature flags
features:
  text_messages: true       # Enable text messages
  media_messages: true      # Enable media (images, videos, documents, audio)
  group_messages: false      # Enable group messages
  presence_updates: true     # Enable presence (online/typing status)
  typing_indicators: true    # Send typing indicators when processing

# WhatsApp bridge settings
whatsapp_bridge:
  auto_setup: true          # Auto-clone Go bridge on first run
  auto_connect: true        # Auto-connect on startup
  bridge_timeout_sec: 180   # Max wait for bridge startup
  poll_interval_sec: 5      # Check for new messages every N seconds

# Logging
logging:
  level: "INFO"              # DEBUG, INFO, WARNING, ERROR
  file: "./logs/agent.log"    # Log file location

3. Run the WhatsApp Agent

Create a simple Python script run_whatsapp.py:

import asyncio
from pathlib import Path
from agntrick_whatsapp import WhatsAppChannel, WhatsAppRouterAgent

async def main():
    # Create channel - storage is where session data is saved
    channel = WhatsAppChannel(
        storage_path="./storage",
        allowed_contact="+34 6XX XXX XXX",  # Your phone number
    )

    # Create and start the router agent
    agent = WhatsAppRouterAgent(
        channel=channel,
        model_name="glm-4.7",
    )

    await agent.start()

asyncio.run(main())

Run it:

python run_whatsapp.py

4. Scan QR Code

On first run, you'll see a QR code in your terminal. Open WhatsApp on your phone:

1. Go to Settings > Linked Devices
2. Tap Link a Device
3. Scan the QR code

That's it! Your agent is now connected and will respond to messages from your allowed contact.

Directory Structure Example

Here's how you can organize a project using the agntrick-whatsapp package:

~/code/agntrick/
├── whatsapp/
│   ├── run_whatsapp.py          # Main entry point
│   ├── whatsapp.yaml            # Configuration file
│   ├── storage/                 # WhatsApp session data (created on first run)
│   └── logs/                   # Application logs
└── prompts/                    # Custom prompts for agents

The storage/ directory contains your WhatsApp session data after QR code login - you don't need to recreate this on subsequent runs.

First Time Setup

1. Install system dependencies (if needed):

   # macOS
   brew install libmagic ffmpeg
   

2. Install the package:

   pip install agntrick-whatsapp
   

3. Create your config file (whatsapp.yaml):

   • Set your phone number in allowed_contact
   • Choose a storage path for session data

4. Run the agent:

   python run_whatsapp.py
   

5. Scan the QR code displayed in your terminal using WhatsApp:

   • Open WhatsApp → Settings → Linked Devices → Link a Device
   • Point your camera at the QR code

6. Start chatting! Send a message from your allowed contact number.

Session Persistence

After the first QR code login, your session is saved in the storage_path directory. On subsequent runs, you don't need to scan again - the agent will auto-connect using the saved session.

Resetting the Session

If you need to re-login (new phone number, etc.), simply delete the storage directory:

rm -rf ./storage

Then run python run_whatsapp.py again to scan a new QR code.

Commands

The router agent supports the following commands:

Examples

• /learn Python decorators - Get a step-by-step tutorial on Python decorators
• /youtube https://youtube.com/watch?v=xyz - Analyze a YouTube video
• /remind in 30 min check the oven - Set a reminder
• /schedule tomorrow 9am assistant summarize news - Schedule a task
• /note Remember to call mom - Save a note
• What's the weather in Tokyo? - General question

Audio Transcription

Voice messages are automatically transcribed using Groq's Whisper API:

from agntrick_whatsapp import AudioTranscriber

transcriber = AudioTranscriber()
result = await transcriber.transcribe_audio("/path/to/voice.ogg")
print(result)

Using as a Local Package

To use your local development version in another project:

cd ~/code/agntrick-whatsapp
uv pip install -e .

Now your other projects will use your local version.

Release

make release VERSION=0.4.0

Troubleshooting

Import Error: "neonize dependency is unavailable"

Install system dependencies and reinstall:

# macOS
brew install libmagic
pip install agntrick-whatsapp --force-reinstall

# Ubuntu/Debian
sudo apt-get install libmagic1
pip install agntrick-whatsapp --force-reinstall

QR Code Not Appearing

1. Check storage path permissions - ensure the directory is writable
2. Delete existing session: rm -rf ./storage (triggers new QR code on next run)
3. Restart the agent

Session Lost / Need to Re-login

Delete the storage directory and run again:

rm -rf ./storage
python run_whatsapp.py

Audio Transcription Not Working

1. Verify Groq API key is set: echo $GROQ_AUDIO_API_KEY
2. Check ffmpeg is installed: ffmpeg -version
3. Voice messages must be under 25MB

Messages Not Being Processed

1. Check that your phone number exactly matches allowed_contact in config
2. Verify logging level - set to DEBUG in config to see what's happening
3. Check logs: tail -f ./logs/agent.log
