Microsoft Azure Communication SMS Client Library for Python
Decision gist · record as of 2026-08-14
Yes, if you are already using Azure Communication Services and need SMS capability in Python. The package is actively maintained, has no known vulnerabilities, supports current Python versions, and integrates cleanly into the Azure SDK ecosystem. Install only if you have an Azure subscription and a provisioned Communication Services resource; it is not useful as a standalone SMS library.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later and a deployed Azure Communication Services resource with a configured phone number.
- Low install friction with a pure-Python wheel distribution.
- Maintained actively as part of the Azure SDK ecosystem with recent commits and stable production status.

What it is and what it does
This package is a Python client library for Azure Communication Services SMS functionality. It wraps the Azure REST API to let you send SMS messages from your application, either to individual recipients or in bulk to multiple phone numbers. The library handles authentication via connection strings or Azure Active Directory, manages the HTTP communication with Azure's backend, and returns structured responses indicating success or failure for each message.
You initialize a client with your Azure credentials, then call the send method with source and destination phone numbers, message text, and optional parameters like delivery reporting and custom tags. The library depends on azure-core for common Azure SDK patterns, msrest for HTTP handling, and typing-extensions for type hints. It's designed for applications that need to integrate SMS notifications, alerts, or two-factor authentication into their workflow.
Use it for
- Send SMS-based two-factor authentication codes during user login or account verification.
- Deliver bulk notification messages to multiple customers about order status, appointments, or service alerts.
- Trigger transactional SMS alerts for system events, outages, or critical monitoring thresholds.
- Send SMS reminders for appointments, reservations, or scheduled events to end users.
- Enable SMS-based customer support workflows where users can receive responses via text message.
