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
