I used the webhook URL in the component but Mailchimp returns this error
"We couldn't verify the URL is working. Please double check and try again. HTTP Code: 503"
My webhook looks like this
http://www.domain.com/index.php?option=com_cmc&format=raw&task=webhooks.request&key=f65beed6f6bab3ebd983ab70225f36ec
Im using SH404SEF if anything...
