Hello,
May be anyone here knows the answer.
The subscription through the website does not work so far.
I think it has something to do with the webhook url and mailchimp api key..
At the end of the webhook url there is a key with a number.
Should this key be the same as the mailchimp api key?
I first had another account connected and think the webhook url has the old key? but may be it should be different and it should be this way.
Anyone knows?
