# exponent-server-sdk — Expo Server SDK for Python

License: permissive · Maintenance: aging · Downloads: 560.5K/mo

## What it is and what it does

This is a Python client library for sending push notifications through Expo's push notification service to mobile apps built with Expo. It wraps the Expo HTTP API and handles the mechanics of formatting and sending notification payloads, including error handling for device registration failures and per-notification errors.

The package is maintained by the Expo community and provides a straightforward interface: you create a PushClient with an optional authenticated session, construct PushMessage objects with device tokens and content, publish them, and validate responses. It depends only on requests for HTTP communication and six for Python 2/3 compatibility, making it lightweight to integrate into existing server applications.

Use it for:

- Send transactional push notifications (alerts, confirmations) from a backend to Expo mobile apps
- Implement retry logic and error reporting for failed push deliveries in production services
- Mark device tokens as inactive when Expo reports a device is no longer registered
- Batch send notifications to multiple users with custom data payloads from a Python service

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Sends push notifications to Expo mobile apps from a Python server using the Expo push notification API.

Yes, if you are building a Python backend for Expo mobile apps and need to send push notifications. The package has low install friction, permissive licensing, and no known vulnerabilities. The aging maintenance status (last release 407 days ago) is a minor concern—verify that the community is still responsive to issues before adopting for new projects, but it remains suitable for established deployments.

## Install

pip install exponent-server-sdk
uv add exponent-server-sdk
poetry add exponent-server-sdk

## Installing exponent-server-sdk

Before you install: Low install friction with only two runtime dependencies (requests and six). Last release was 407 days ago; maintenance status is aging but the repository remains active and not archived.

License in practice: MIT license permits commercial and private use with minimal restrictions—suitable for most production deployments.

Quickstart:

pip install exponent-server-sdk

from exponent_server_sdk import PushClient, PushMessage
import requests

session = requests.Session()
session.headers.update({"Authorization": f"Bearer {token}"})
response = PushClient(session=session).publish(
    PushMessage(to=device_token, body="Hello")
)
response.validate_response()

Verify before relying:

- Whether the package supports modern Python versions (requires_python is unspecified in metadata)
- Current status of community maintenance and typical response time for issues
- Whether six dependency is still necessary given Python 2 end-of-life
