需要帮助解决 OpenClaw WhatsApp 网络钩子（webhook）设置错误

If you are using a self-signed SSL certificate, WhatsApp won't accept it. Use a certificate from a trusted CA like Let's Encrypt.

Check your server logs to see if the verification requests are actually hitting your endpoint. Sometimes network routing issues prevent the request from reaching your webhook.

I used ngrok to expose my local server temporarily for testing, and that helped me isolate the problem more quickly.

Make sure that your webhook URL does not redirect to another URL. WhatsApp requires a direct response from the URL provided.

Double-check the webhook verification token you set in your OpenClaw config matches exactly what you have in your WhatsApp Business API settings. Mismatches there cause verification failures.

Also, ensure your endpoint responds to the GET request with the 'hub.challenge' parameter as per WhatsApp webhook verification specs.

I had the same issue. Make sure your webhook URL is publicly accessible and uses HTTPS with a valid certificate. Also, check that your server responds correctly to the verification challenge sent by WhatsApp.
