aiofcm is a library designed specifically for sending messages such as push-notifications to Android devices via Firebase Cloud Messaging platform. aiofcm provides an efficient client through asynchronous XMPP protocol for use with Python's asyncio framework.

aiofcm requires Python 3.5 or later.

In my testing aiofcm allows you to send on average 1k messages per second on a single core.

• Internal connection pool which adapts to the current load
• Sending notification and/or data messages
• Ability to set TTL (time to live) for messages
• Ability to set priority for messages
• Ability to set collapse-key for messages

Use pip to install:

$ pip install aiofcm

from uuid import uuid4
from aiofcm import FCM, Message, PRIORITY_HIGH


async def run():
    fcm = FCM('<NUMERICAL_SENDER_ID>', '<API_KEY>')
    message = Message(
        device_token='<DEVICE_TOKEN>',
        notification={           # optional
            "title": "Hello from Firebase",
            "body": "This is notification",
            "sound": "default"
        },
        data={"score": "3x1"},   # optional
        message_id=str(uuid4())  # optional
        time_to_live=3,          # optional
        priority=PRIORITY_HIGH,  # optional
    )
    await fcm.send_message(message)

loop = asyncio.get_event_loop()
loop.run_until_complete(run())
