Connecting OpenClaw to WhatsApp requires navigating Meta's WhatsApp Business API, which involves business account verification, webhook configuration, and template message approval. This advanced guide walks you through every step of the integration process, from Meta Business account creation to handling media and rich messages.
Why This Is Hard to Do Yourself
These are the common pitfalls that trip people up.
Business API complexity
WhatsApp requires a Meta Business account, app creation, phone number verification, and webhook setup before sending a single message
Webhook verification
WhatsApp uses a challenge-response verification flow that must be handled correctly or your webhook never receives messages
Template requirements
You can't send proactive messages without pre-approved templates. Template approval takes 24-48 hours.
24-hour messaging window
After 24 hours of inactivity, you can only send template messages, not free-form responses
