Here is a simple Python program that can be used to:
- Test the API
- Get a list of Slack Users
- Get a list of Slack Channels
- Get information about a Slack Channel
- Post a message to Slack Channel
Students in my Intro to Programming and Problems Solving class at Clark College learn how to build this and other things using Python.
Have fun with it!
