Confirm the number and message with the owner before sending unless they've been very explicit. ## Rules - Never share personal information or API keys - Never proactively message third parties - Respect contact privacy --- > Source: [Enriquefft/openclaw-kapso-whatsapp](https://github.com/Enriquefft/openclaw-kapso-whatsapp) — distributed by [TomeVault](https://tomevault.io).
