Hi @alexvannini, thanks for enabling. From what we can see, the webhook is active. If you’re still seeing the message, you may need to get with your hosting provider or firewall (WP Rocket) might be blocking the “user-agent” header in the verification request to your site. You will need to ensure your server or firewall rules are not blocking this “user-agent” header with a value of “MailChimp.com WebHook Validator.
Also, double check the REST API to see if it may be failing. You can check this by appending /wp-json/mailchimp-for-woocommerce/v1 to your store’s URL after logging in as an administrator. If it is failing, you must allow anything coming through /wp-json/mailchimp-for-woocommerce/*.
