telnyx
The official Python library for the telnyx API
Decision gist · record as of 2026-08-14
Yes. The library is actively maintained, has no known vulnerabilities, uses permissive MIT licensing, and offers low install friction. It is the official Telnyx SDK with full type support and both sync/async interfaces—the right choice for any Python application integrating Telnyx communications services.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; TELNYX_API_KEY environment variable or explicit api_key parameter needed to authenticate.
- Low install friction with a pure-Python wheel and six common dependencies (anyio, distro, httpx, pydantic, sniffio, typing-extensions).
- Actively maintained with a release 2 days old and recent commits.

What it is and what it does
Telnyx is the official Python SDK for the Telnyx communications platform REST API. It wraps HTTP calls to Telnyx's endpoints with a typed, object-oriented interface, supporting both synchronous and asynchronous workflows. The library is generated using Stainless and includes full type hints for all request parameters and response fields, enabling IDE autocomplete and static type checking.
The package is built on httpx for HTTP transport and pydantic for response validation. It handles pagination automatically, provides helper methods for serializing responses to JSON or dictionaries, and includes error classes for connection and API status failures. Async usage is identical to sync except for await keywords; you can optionally swap httpx for aiohttp as the HTTP backend for improved concurrency performance.
Use it for
- Programmatically dial phone calls, manage connections, and configure answering machine detection in voice applications.
- Build IVR systems or contact center integrations that need to interact with Telnyx's telephony platform.
- Transcribe audio files or access AI-powered communication features via the Telnyx API.
- Manage phone numbers, access IP addresses, and handle number orders through the REST API.
- Integrate Telnyx webhooks and event handling into async Python applications with type safety.
