MailChimp API 3 integration with Joomla!

*About project* The main project is to create a simple integration between Joomla! and MailChimp using the Mailchimp v3 API: [login to view URL] *End-result* Custom integration with function for adding/removing groups and e-mails I want to be able to add a code like addToMailchimp(“list-id-x”, “email@[login to view URL]”, “group-ids for user”); in some custom modules and components and this would send command using API that would. 1. Check if there is a user with e-mail email@[login to view URL] in list list-id-x 2. If there is a user then update with new group-ids (interests) 3. If no user then create user with group-ids (interests). 4. Group-ids could be a single one or a list of groups separated by comma. Example code in JSON for adding a user to group (in API called interests): hds37sdhh27 {"email_address": "email@[login to view URL]", "status": "subscribed", "interests": {"hds37sdhh27":true} } Also there should be a function for removing user from groups. removeGroupsMailchimp(“list-id-x”, “email@[login to view URL]”, “group-ids for user”); This would remove group-ids (interests) from user. So for example a user would fill in her e-mail adress in a simple form in Joomla! module and as user data is saved in local database it would also add/update in Mailchimp for example by removing user from interests in one list and adding them to another list. The functions should give true if everything works but mail med an error message if it doesn’t work. *Add user email to mailchimp when user confirms email in Joomla!* So when user registers, gets activation link and clicks it so that user account is activated in Joomla! then it should also send user e-mail to mailchimp automatically. And also add it to specific interests/group. Perhaps using a plugin like this? [login to view URL] *Send custom trigger to MailChimp when Joomla! action* For example if user is part of group x and not part of group y and hasn’t logged in for 7 days it would send a post trigger to [login to view URL] to activate a mailchimp automation trigger: Where mailchimp would send a mail to the customer. Important here that it is == 7 days and not >= 7 days so users will not get e-mails over and over and so on. Another example would be when user posts first post in a forum. *Simple functionality* There will not need to be a complete integration with mailchimp and campaigns, reports and so on will not be managed through joomla! or API. Just "simple" user managment for different lists.
