Configuring app

The cleaner needs you to give Slack's API permission to let it run the operations it needs. You grant these by registering it as an app in the workspace you want to use it in.

You can grant these permissions to the app by:

  1. going to Your Apps
  2. select 'Create New App', fill out an App Name (eg 'Slack Cleaner') and select the Slack workspace you want to use it in
  3. select 'OAuth & Permissions' in the sidebar
  4. scroll down to Scopes and select all scopes you need
  5. select 'Save changes'
  6. select 'Install App to Workspace'
  7. review the permissions and press 'Authorize'
  8. copy the 'OAuth Access Token' shown, and use this token as the --token argument to the script

Tips

After the task, a backup file slack-cleaner.<timestamp>.log will be created in current directory if --log is supplied.

If any API problem occurred, try --rate=<delay-in-seconds> to reduce the API call rate (which by default is unlimited).

If you see the following warning from urllib3, consider to install missing packages: pip install --upgrade requests[security] or just upgrade your Python to 2.7.9.

InsecurePlatformWarning: A true SSLContext object is not available.
          This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.
          For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
