pyapns_client

Simple, flexible and fast Apple Push Notifications on iOS, OSX and Safari using the HTTP/2 Push provider API.

Features

• Uses the new Apple APNs HTTP/2 protocol with persistent connections
• Uses token-based authentication (no need to renew your certificates anymore)
• Uses the httpx HTTP client library
• Supports the new iOS 10 features such as Collapse IDs, Subtitles and Mutable Notifications
• Makes the integration and error handling really simple with auto-retry on APNs errors

Cautions

• Works only with Python 3.6 and higher

Installation

Install using pip:

pip install pyapns_client

Usage

from pyapns_client import APNSClient, IOSPayloadAlert, IOSPayload, IOSNotification, APNSDeviceException, APNSServerException, APNSProgrammingException, UnregisteredException


client = APNSClient(mode=APNSClient.MODE_DEV, root_cert_path='/path/to/root_cert.pem', auth_key_path='/path/to/auth_key.p8', auth_key_id='AUTHKEY123', team_id='TEAMID1234')
# `root_cert_path` is for the AAACertificateServices root cert (https://apple.co/3mZ5rB6)
# with token-based auth you don't need to create / renew your APNS SSL certificates anymore
# you can pass `None` to `root_cert_path` if you have the cert included in your trust store
# httpx uses 'SSL_CERT_FILE' and 'SSL_CERT_DIR' from `os.environ` to find your trust store

try:
    device_tokens = ['device_token_1', 'device_token_2']
    alert = IOSPayloadAlert(title='Title', subtitle='Subtitle', body='Some message.')
    payload = IOSPayload(alert=alert)
    notification = IOSNotification(payload=payload, topic='domain.organization.app')

    for device_token in device_tokens:
        try:
            client.push(notification=notification, device_token=device_token)
        except UnregisteredException as e:
            print(f'device is unregistered, compare timestamp {e.timestamp_datetime} and remove from db')
        except APNSDeviceException:
            print('flag the device as potentially invalid and remove from db after a few tries')
        except APNSServerException:
            print('try again later')
        except APNSProgrammingException:
            print('check your code and try again later')
        else:
            print('everything is ok')
finally:
    client.close()
