aioapns - An efficient APNs Client Library for Python/asyncio

aioapns is a library designed specifically for sending push-notifications to iOS devices via Apple Push Notification Service. aioapns provides an efficient client through asynchronous HTTP2 protocol for use with Python's asyncio framework.

aioapns requires Python 3.6 or later.

Performance

In my testing aioapns allows you to send on average 1.3k notifications per second on a single core.

Features

Internal connection pool which adapts to the current load
Support for certificate and token based connections
Ability to set TTL (time to live) for notifications
Ability to set priority for notifications
Ability to set collapse-key for notifications
Ability to use production or development APNs server

Installation

Use pip to install:

$ pip install aioapns

Basic Usage

import asyncio
from uuid import uuid4
from aioapns import APNs, NotificationRequest, PushType


async def run():
    apns_cert_client = APNs(
        client_cert='/path/to/apns-cert.pem',
        use_sandbox=False,
    )
    apns_key_client = APNs(
        key='/path/to/apns-key.p8',
        key_id='<KEY_ID>',
        team_id='<TEAM_ID>',
        topic='<APNS_TOPIC>',  # Bundle ID
        use_sandbox=False,
    )
    request = NotificationRequest(
        device_token='<DEVICE_TOKEN>',
        message = {
            "aps": {
                "alert": "Hello from APNs",
                "badge": "1",
            }
        },
        notification_id=str(uuid4()),  # optional
        time_to_live=3,                # optional
        push_type=PushType.ALERT,      # optional
    )
    await apns_cert_client.send_notification(request)
    await apns_key_client.send_notification(request)

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