AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

The Slack Python SDK provides a unified interface to Slack's APIs—Web, RTM, OAuth, Webhooks, Socket Mode, Audit Logs, and SCIM—enabling you to build Slack apps and integrations with message posting, file uploads, request verification, and user management.

Low friction: pure-Python wheel with zero runtime dependencies. Actively maintained with a release 44 days ago. Supports Python 3.7–3.14 and PyPy.

MIT license (permissive) places no restrictions on use, modification, or distribution in commercial or private projects.

Usage

pip install slack_sdk

import os
from slack_sdk import WebClient

client = WebClient(token=os.environ['SLACK_BOT_TOKEN'])
response = client.chat_postMessage(channel='#random', text='Hello world!')

Requires Python 3.7 or higher and a valid Slack bot token in the SLACK_BOT_TOKEN environment variable.

Verdict: Production-ready SDK with active maintenance, no dependencies, and permissive MIT licensing. Suitable for any scale of Slack app development from simple bots to complex integrations. No known security vulnerabilities.
