It handles the subscription handshake, credential management, and asynchronous message delivery to your application\u2014useful when you need to listen for notifications on a backend or desktop Python process rather than on a mobile or web platform.\n\nThe library runs inside an asyncio event loop and exposes a callback-based API: you provide a notification handler, Firebase credentials, and configuration, then call start() to begin listening. It manages the underlying HTTP/2 connection to FCM, handles encryption/decryption of incoming messages using http-ece and cryptography, and invokes your callback each time a notification arrives. It is not for sending notifications\u2014use the official Firebase SDK for that.","worth_installing":"Yes, if you need to receive FCM notifications in a Python application. The library is actively maintained, has low install friction, carries no known vulnerabilities, and supports modern Python versions. The MIT license imposes no restrictions. Install it only if you are receiving (not sending) notifications and your application is not already running on a supported FCM platform."},"id":"firebase-messaging","links":{"html":"https://skillfed.io/packages/firebase-messaging","md":"https://skillfed.io/packages/firebase-messaging.md","pypi":"https://pypi.org/project/firebase-messaging/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-05-10","license_spdx":null,"license_treatment":"permissive","name":"firebase-messaging","python_support":"supports_current","summary":"FCM/GCM push notification client"},"popularity":{"monthly_downloads":191754,"position":9876,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.4.5"}
