Webhook Has Not Been Setup Error
Welcome to the guide on troubleshooting the Webhook Setup Error in the MailChimp for WooCommerce Integration. This guide will help you understand the potential issues with your hosting environment that could cause this error and how to resolve them.
If you encounter the error message "Mailchimp for WooCommerce has not added the webhook to Mailchimp", it could be due to several issues with your hosting environment. Despite this error, data continues to be transferred from your store to Mailchimp.
Ensure you're using the latest version of the plugin and that you're running the required minimum versions of WordPress, WooCommerce, and PHP.
After confirming your version updates, navigate to the 'Settings' tab of the plugin and enable 'Remote diagnostics'. The plugin will attempt to reactivate the webhook remotely every few hours.
If the error persists after a few days, it's possible that your hosting provider or firewall service is blocking access from the Mailchimp servers that are trying to verify your webhook. Consult with your site host to see if they're blocking anything coming to this endpoint:

/wp-json/mailchimp-for-woocommerce/v1/pingto see if this feature is turned off for our API path.
If the previous step fails, you'll need to allow anything coming through:
/wp-json/mailchimp-for-woocommerce/v1/member-syncin your firewall.
