👨‍💻 Usage#

  • Create a WhatsApp client and send a message ..

    See Getting Started for more information.

from pywa import WhatsApp

wa = WhatsApp(
    phone_id="100458559237541",
    token="EAAEZC6hUxkTIB"
)

wa.send_message(
    to="9876543210",
    text="Hello from PyWa!"
)

  • To listen to updates, create a WhatsApp client, pass a web server app (FastAPI in this example) and register callbacks:

See Handlers for more information.

# wa.py
from pywa import WhatsApp, filters
from pywa.types import Message, CallbackButton, Button
from fastapi import FastAPI

fastapi_app = FastAPI()
wa = WhatsApp(
    phone_id="1234567890",
    token="xxxxxxx",
    server=fastapi_app,
    callback_url="https://yourdomain.com/",
    verify_token="xyz123",
    app_id=123456,
    app_secret="yyyyyy"
)

@wa.on_message(filters.matches("Hello", "Hi"))
def hello(client: WhatsApp, msg: Message):
    msg.react("👋")
    msg.reply_text(
        text=f"Hello {msg.from_user.name}!",
        buttons=[
            Button(
                title="Click me!",
                callback_data="id:123"
            )
        ]
    )

@wa.on_callback_button(filters.startswith("id"))
def click_me(client: WhatsApp, clb: CallbackButton):
    clb.reply_text("You clicked me!")

  • To run the server, use uvicorn (pip install "uvicorn[standard]"):

uvicorn wa:fastapi_app  # see uvicorn docs for more options (port, host, reload, etc.)

💫 Async Usage

  • PyWa has async support! To use the async version, replace all the imports from pywa to pywa_async and use async/await:

# wa.py
import fastapi
from pywa_async import WhatsApp, types

fastapi_app = fastapi.FastAPI()
wa = WhatsApp(..., server=fastapi_app)

async def main():
    await wa.send_message(...)

@wa.on_message()
async def hello(_: WhatsApp, msg: types.Message):
    await msg.react("👋")
    await msg.reply(...)

uvicorn wa:fastapi_app

🎛 Installation#

  • Install using pip3:

pip3 install -U pywa
