Python Slack SDK

The Slack platform offers several APIs to build apps. Each Slack API delivers part of the capabilities from the platform, so that you can pick just those that fit for your needs. This SDK offers a corresponding package for each of Slack’s APIs. They are small and powerful when used independently, and work seamlessly when used together, too.


What its for



Send data to or query data from Slack using any of over 200 methods.

slack_sdk.web slack_sdk.web.async_client

Webhooks / response_url

Send a message using Incoming Webhooks or response_url

slack_sdk.webhook slack_sdk.webhook.async_client


Setup the authentication flow using V2 OAuth for Slack apps.



Listen for incoming messages and a limited set of events happening in Slack, using WebSocket.


Request Signature Verification

Verify incoming requests from the Slack API servers.


UI Builders

Construct UI components using easy-to-use builders.



This package supports Python 3.6 and higher. We recommend using PyPI to install Python Slack SDK

pip install slack_sdk

Of course, you can always pull the source code directly into your project:

git clone

And then, save a few lines of code as ./

import sys
# Load the local source directly
sys.path.insert(1, "./python-slack-sdk")
# Enable debug logging
import logging
# Verify it works
from slack_sdk import WebClient
client = WebClient()
api_response = client.api_test()

You can run the code this way.


It’s also good to try on the Python REPL.
