trycourier

What it is and what it does

Trycourier is the official Python SDK for Courier's notification platform API. It provides a typed, synchronous and asynchronous client to send messages through Courier's infrastructure, manage user profiles, track message delivery status, and generate JWT tokens for embedding Courier's client-side SDKs in web or mobile applications. The package wraps Courier's REST API and handles authentication via the COURIER_API_KEY environment variable or explicit configuration.

The SDK is built on httpx for HTTP transport, pydantic for request/response validation, and anyio for async support. It supports Python 3.9 and later. Installation is straightforward via pip, and the library is actively maintained with no known security vulnerabilities.

Use it for:

• Send transactional notifications (emails, SMS, push) to users via a single API call with template support
• Build notification management dashboards that track message delivery status and user preferences
• Embed Courier's client-side SDKs in web applications by issuing JWT tokens server-side
• Manage user contact information and notification preferences programmatically
• Integrate multi-channel notifications into Python backend services without managing individual provider APIs

AI-flagged interpretation of the facts on this page — verify before relying

A typed Python client for the Courier REST API that sends notifications, manages user profiles, checks message status, and issues JWT tokens for client-side SDKs.

Yes. The package is actively maintained, has low install friction, carries a permissive license, and has no known vulnerabilities. It is the official SDK for Courier's API and suitable for any Python application that needs to send or manage notifications through Courier's platform.

trycourier on PyPI

pip install trycourier

uv add trycourier

poetry add trycourier

Installing trycourier

Before you install

Low friction install with a pure-Python wheel. Actively maintained as of 2026-08-14 with recent release. Depends on well-established libraries with no compiled dependencies.

License in practice

Apache-2.0 permissive license allows commercial and private use with minimal restrictions; suitable for most projects.

Quickstart

pip install trycourier

import os
from trycourier import Courier

client = Courier(api_key=os.environ.get("COURIER_API_KEY"))
response = client.send.message(
    message={
        "to": {"user_id": "your_user_id"},
        "template": "your_template_id",
        "data": {"foo": "bar"},
    },
)
print(response.request_id)

Requires Python 3.9 or later; COURIER_API_KEY environment variable or explicit api_key parameter needed for authentication.

Verify before relying

• Whether the async client (AsyncCourier) is feature-complete relative to the sync client
• Rate limiting or quota behavior when calling the Courier API through this SDK
• Retry and timeout defaults and whether they are configurable
• Specific capabilities beyond send, profile management, status checking, and JWT token issuance
