Configuration

Customize your OCA installation — Node.js, OpenClaw config, and environment variables.

OpenClaw Config

Config lives at ~/.openclaw/openclaw.json:

{
  "channels": {
    "whatsapp": {
      "allowFrom": ["+91XXXXXXXXXX"],
      "groups": { "*": { "requireMention": true } }
    }
  },
  "messages": {
    "groupChat": {
      "mentionPatterns": ["@openclaw"]
    }
  }
}

Edit with:

nano ~/.openclaw/openclaw.json
