Authentication

Create a Slack app and bot token. Grant only scopes required by the selected streams. Common scopes include channel history/read/join, group read, file read, reaction read, team read, user-group read, and user read. Add users:read.email only when email extraction is required. Invite the bot to private or non-auto-joined channels.

The lookback window repeats recent data so child streams can capture late changes. Increasing it raises API and target load. Verify channel visibility, rate-limit recovery, edited/deleted messages, and high-volume channel windows before production use.
