🔌 Client#

The WhatsApp client has 3 main responsibilities:

Sending messages (text, media, location, contact, etc.)
Listening for incoming messages and events
Creating and managing templates, flows, profile and other business-related resources

Tip

Pywa provides two clients, synchronous and asynchronous, you can choose the one that fits your needs.

from pywa import WhatsApp, types
wa = WhatsApp(...)

@wa.on_message
def on_message(_: WhatsApp, msg: types.Message):
    msg.reply("Hello!")

from pywa_async import WhatsApp, types
wa = WhatsApp(...)

@wa.on_message
async def on_message(_: WhatsApp, msg: types.Message):
    await msg.reply("Hello!")

class pywa.client.WhatsApp#

The WhatsApp client.

Full documentation on pywa.readthedocs.io.

Example without webhook:

>>> from pywa import WhatsApp
>>> wa = WhatsApp(phone_id="1234567890",token="EAADKQl9oJxx")
>>> wa.send_message("1234567890", "Hello from PyWa!")

Example with webhook (using FastAPI):

>>> import pywa, fastapi
>>> fastapi_app = fastapi.FastAPI()
>>> wa = pywa.WhatsApp(
...     phone_id="1234567890",
...     token="EAADKQl9oJxx",
...     server=fastapi_app,
...     callback_url='https://pywa.ngrok.io',
...     verify_token="XYZ123",
...     app_id=1234567890,
...     app_secret="my_app_secret",
... )

>>> @wa.on_message(filters.text)
... def new_message(_: WhatsApp, msg: Message):
...     msg.reply("Hello from PyWa!")

$ fastapi dev wa.py see uvicorn docs for more options (port, host, reload, etc.)

Parameters:

phone_id – The Phone number ID to send messages from (if you manage multiple WhatsApp business accounts (e.g. partner solutions), you can specify the phone ID when sending messages, optional).
token – The token to use for WhatsApp Cloud API (In production, you should use permanent token).
api_version – The API version of the WhatsApp Cloud API (default to the latest version).
session – The session to use for api requests (default: new httpx.Client(), For cases where you want to use a custom session, e.g. for proxy support. Do not use the same session across multiple WhatsApp clients!).
server – The Flask or FastAPI app instance to use for the webhook. required when you want to handle incoming updates. pass None to insert the updates with the webhook_update_handler().
callback_url – The server URL to register (without endpoint. optional).
callback_url_scope – The scope of the callback URL to register (default: APP).
verify_token – A challenge string (Required when server is provided. The verify token can be any string. It is used to challenge the webhook endpoint to verify that the endpoint is valid).
webhook_challenge_delay – The delay (in seconds, default to 3) to wait for the verify token to be sent to the server (optional, for cases where the server/network is slow or the server is taking a long time to start).
webhook_fields – The fields to register for the callback URL (optional, if not provided, all supported fields will be registered. modify this if you want to reduce the number of unused requests to your server). See Availble fields.
app_id – The ID of the app in the App Basic Settings (optional, required when registering a callback_url).
app_secret –
The secret of the app in the App Basic Settings (optional, recomended for validating updates, required when registering a callback_url).
webhook_endpoint – The endpoint to listen for incoming messages (if you’re using the server for another purpose, you can change this to avoid conflicts).
filter_updates – Whether to filter out user updates that are not sent to this phone_id (default: True, does not apply to raw updates or updates that are not user-related).
business_account_id – The WhatsApp business account ID (WABA ID) that owns the phone ID (optional, required for some API methods).
business_private_key – The global private key to use in the flows_request_decryptor
business_private_key_password – The global private key password (if needed) to use in the flows_request_decryptor
flows_request_decryptor – The global flows requests decryptor implementation to use to decrypt Flows requests.
flows_response_encryptor – The global flows response encryptor implementation to use to encrypt Flows responses.
continue_handling – Whether to continue handling updates after a handler or listener has been found (default: False).
skip_duplicate_updates – Whether to skip duplicate updates (default: True).
validate_updates – Whether to validate updates payloads (default: True, app_secret required).
handlers_modules – Modules to load handlers from.
