Autoarchive unused slack channels

Requirements

• python2.7/python3
• Install requirements.txt ( pip install -r requirements.txt )
• Slack API token (https://api.slack.com/docs/oauth-test-tokens)

Example Usages

The SLACK_TOKEN must be exposed as a environment variable before running your script. By default, the script will do a DRY_RUN. To perform a non-dry run, specify DRY_RUN=false as an environment variable as well. See sample usages below.

# Run the script in dry run archive mode...This will output a list of channels that will be archived.
SLACK_TOKEN=<TOKEN> python slack-autoarchive.py

# Run the script in active archive mode...THIS WILL ARCHIVE CHANNELS!
DRY_RUN=false SLACK_TOKEN=<TOKEN> python slack-autoarchive.py

What Channels Will Be Archived

A channel will be archived by this script is it doesn't meet any of the following criteria:

• Has non-bot messages in the past 60 days.
• Is whitelisted. A channel is considered to be whitelisted if the channel name contains keywords in the WHITELIST_KEYWORDS environment variable. Multiple keywords can be provided, separated by comma.

What Happens When A Channel Is Archived By This Script

• Don't panic! It can be unarchived from https://slack.com/archives/archived However all previous members would be kicked out of the channel and not be automatically invited back.
• A message will be dropped into the channel saying the channel is being auto archived because of low activity
• You can always whitelist a channel if it indeed needs to be kept depsite meeting the auto-archive criteria.
