I am trying to set up the OpenClaw WhatsApp webhook integration, but I keep encountering an error during the setup process. The webhook URL doesn't seem to receive any verification requests, or when it does, it returns an error. Has anyone faced similar issues or knows how to fix this? Any guidance or step-by-step instructions would be highly appreciated.

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.
