whatsloon

A Python wrapper facilitating seamless integration with the WhatsApp Cloud API. Streamline your messaging workflows and enhance user engagement with this efficient toolkit.

Overview

whatsloon is a robust Python SDK for the WhatsApp Cloud API. It provides a comprehensive set of mixin classes and utilities to send all supported WhatsApp message types, including text, media, interactive, template, location, reaction, sticker, and more. The package is designed for both synchronous and asynchronous workflows, with strong validation and error handling.

Features

• Send Text, Image, Video, Audio, and Document messages
• Send Interactive messages: Lists, Reply Buttons, Flows, CTA buttons
• Send Location and Location Request messages
• Send Contact and Address messages
• Send Template messages (with components)
• Send Stickers and Reactions
• Send Typing Indicators
• Mark messages as Read
• Robust validation for API limits (e.g., button/section/row limits)
• Both synchronous and asynchronous support (requests and httpx)
• Clear error handling and logging

Key Components

• Mixin Classes: Each message type (text, image, video, audio, document, list, flow, reply buttons, template, sticker, reaction, location, location request, contact, address, typing indicator, read receipt) is implemented as a robust, reusable mixin class.
• WhatsAppBaseClient: Easily compose your own client by combining mixins for only the features you need.
• Validation: All payload builders validate API limits and required fields.
• Async & Sync: All senders support both synchronous (requests) and asynchronous (httpx) usage.

Installation

pip install whatsloon

Usage Examples

1. Using WhatsAppCloudAPIClient (All Features, Easiest)

from whatsloon import WhatsAppCloudAPIClient

client = WhatsAppCloudAPIClient(
    access_token="YOUR_API_KEY",
    mobile_number_id="MOBILE_NUMBER_ID",
    recipient_country_code="91",
    recipient_mobile_number="9876543210",
)

# Synchronous usage
result = client.send_text_message("Hello, world!", preview_url=True)
print(result)

# Asynchronous usage
import asyncio
async def main():
    result = await client.async_send_text_message("Hello async!", preview_url=True)
    print(result)
asyncio.run(main())

# Send an image (sync)
result = client.send_image_message(media_id="MEDIA_ID", caption="A photo")
print(result)

# Send an image (async)
async def main_img():
    result = await client.async_send_image_message(media_id="MEDIA_ID", caption="Async photo")
    print(result)
asyncio.run(main_img())

2. Composing Your Own Client (Selected Features Only)

# Import mixins directly from the package root
from whatsloon import WhatsAppBaseClient, TextSender, ImageSender

class MyWhatsAppClient(WhatsAppBaseClient, TextSender, ImageSender):
    pass

client = MyWhatsAppClient(
    access_token="YOUR_API_KEY",
    mobile_number_id="MOBILE_NUMBER_ID",
    recipient_country_code="91",
    recipient_mobile_number="9876543210",
)

# Use only the features you mix in
result = client.send_text_message("Hello, world!", preview_url=True)
print(result)

3. Without Mixins (Direct Usage)

from whatsloon import WhatsAppBaseClient

class SimpleClient(WhatsAppBaseClient):
    pass

client = SimpleClient(
    access_token="YOUR_API_KEY",
    mobile_number_id="MOBILE_NUMBER_ID",
    recipient_country_code="91",
    recipient_mobile_number="9876543210",
)

# You can use the generic send_message method for custom payloads:
payload = {
    "type": "text",
    "text": {"body": "Hello from custom payload!"}
}
result = client.send_message(payload)
print(result)

# Async version
import asyncio
async def main():
    result = await client.async_send_message(payload)
    print(result)
asyncio.run(main())

Testing

whatsloon includes comprehensive tests for all mixins, message types, and integration scenarios.
