I solved my problem. My old server not support to install CURL, i changed to new server with curl installed and the integrations was work well. Thanks a lot!
Im using a windows server, how can i use this integration in this kind of server?
Sorry but in mailchimp website they recomend that dont provide the api key for anybody cause security reasons.
I noticed that this integration problem only ocurs in my production environment, in my local environment the integration works perfectly. Does this information help?
