How to Automate WhatsApp with Python in 2026

Every WhatsApp automation tutorial still recommends selenium with fragile XPath selectors that break every week. There's a better way.

Why Playwright + whatsplay?

Playwright is faster, more reliable, and whatsplay wraps the WhatsApp Web DOM with stable selectors (attribute-based instead of minified class names).

What you'll build
A bot that monitors a price and sends an alert to your WhatsApp group.

Install
pip install whatsplay playwright
playwright install chromium

Step 1: Connect to WhatsApp
from whatsplay import Client

client = Client()
client.launch()
client.wait_for_login()

Step 2: Send a message
chat = client.get_chat("Mi Grupo")
chat.send_message("¡Hola! Esto es automático 🤖")

Step 3: Monitor + alert (real use case)
import httpx

def check_price():
r = httpx.get("https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd")
return r.json()["bitcoin"]["usd"]

@client.on_message()
def handler(msg):
if msg.text and "precio" in msg.text.lower():
price = check_price()
chat.send_message(f"BTC está en ${price:,}")

Why this approach wins

Selectors don't break on WhatsApp updates
Works with QR login, persistent sessions
34 tests covering message parsing, timestamps, voice messages
