Slack Integration

by @charlie-morrison

Slack messaging — send messages, manage channels, upload files, add reactions, and automate team notifications via CLI and API.

Versionv1.0.0
#requires-oauth-token#requires-sensitive-credentials#clawhub
⚙️ Configuration

# 1. Create a Slack App: https://api.slack.com/apps → Create New App

2. Add scopes under OAuth & Permissions:


   Bot Token Scopes: chat:write, channels:read, channels:history,


                     files:write, reactions:write, users:read


3. Install to workspace → copy Bot User OAuth Token
export SLACK_TOKEN="xoxb-..."   # Bot token (starts with xoxb-)

For user-level actions (DMs to yourself, custom status), use a User OAuth Token (xoxp-...) instead.

📋 Tips & Best Practices

  • Bot tokens (xoxb-) can only post to channels the bot has been invited to
  • Rate limits: ~1 msg/sec per channel (Tier 2); respect Retry-After headers
  • Channel IDs (not names) are required for most API calls — look them up first
  • For rich messages, use Block Kit Builder to design layouts
  • mrkdwn (Slack's markdown) uses *bold*, _italic_, ~strike~, ` code , >quote
  • DMs: use conversations.open` with user IDs to get the DM channel ID, then post normally
