Slack

Slack is production-ready in OpenClaw for DMs and channels, and Nexu inherits the same setup model.

What you need

• A Slack app
• A bot token xoxb-...
• Either:
  • an app token xapp-... for Socket Mode, or
  • a signing secret for HTTP Events API mode

Recommended mode

Use Socket Mode unless you have a strong reason to receive events over HTTP.

Socket Mode checklist

1. Create the Slack app.
2. Enable Socket Mode.
3. Create an app token with connections:write.
4. Install the app and copy the bot token.
5. Subscribe to message and mention events.
6. Enable App Home messages for DMs.
7. Start the gateway.

Example config

{
  channels: {
    slack: {
      enabled: true,
      mode: "socket",
      appToken: "xapp-...",
      botToken: "xoxb-...",
    },
  },
}

Common policy settings

• dmPolicy: pairing, allowlist, open, or disabled
• groupPolicy: open, allowlist, or disabled
• channels.slack.channels: stable Slack channel IDs for allowlists
• requireMention: keep it on for shared channels, turn it off only in trusted spaces
