A stateful WhatsApp API Wrapper for Python with built-in conversation flow management. Currently supports abstraction for Azure Communication Services.

Example

import os

from wasup import Bot
from wasup.bindings.azure import AzureBindingClient
from wasup.messages import TextMessage
from wasup.messages.dialogs import Dialog, DialogTurnResult, DialogTurnStatus, DialogContext

# initialize dialog with name and main flag
@Dialog.set(name="GreetingDialog", main=True)
class GreetingDialog(Dialog):
    """A simple greeting dialog that asks for the user's name."""

    @Dialog.step()
    @Dialog.store("user_name")
    async def ask_name(self, dc: DialogContext):
        """Ask the user for their name."""
        message = TextMessage(ctx=dc.ctx, message="Hello! 👋 What's your name?")
        await dc.message.send(message)
        return DialogTurnResult(DialogTurnStatus.Waiting)

    @Dialog.step()
    async def greet_user(self, dc: DialogContext):
        """Greet the user by name."""
        name = dc.get_value("user_name")
        message = TextMessage(ctx=dc.ctx, message=f"Nice to meet you, {name}! 😊")
        await dc.message.send(message)
        return DialogTurnResult(DialogTurnStatus.Complete)

# create bot instance
bot = Bot()

# load all dialogs
bot.load_dialog(GreetingDialog)

# initialize azure client
acs_client = NotificationMessagesClient.from_connection_string(os.getenv("AZURE_COMMUNICATION_ENDPOINT"))
azure_binding = AzureBindingClient(
    ctx=bot,
    client=acs_client,
    route="/api/whatsapp/events",
)

# run the bot with azure binding
bot.run(azure_binding)
