First of all, if you don’t have an account, register one on MailChimp.
Now go to http://admin.mailchimp.com/account/api/ and create a new API key with the related button, as you can see below.
After creating it, copy and paste the key in the “MailChimp API Key” field that you find in the plugin settings dashboard.
If no mistakes were made, validation will be correctly done and you will see the information about the linked MailChimp account.
This option, available in the tab Integration, allows you to enable a specific type of system to track purchases deriving from a campaign (Discover MailChimp campaigns).
It is essential that during the campaign creation, the option eCommerce 360 link tracking is enabled.
If these settings have been enabled, both in the plugin and in MailChimp, MailChimp will “append” the data “mc_cid” and “mc_eid” to the email that will be generated.
As soon as the user clicks on the link in the email, the shop will store data in a cookie and keep them until checkout, for a maximum time-lapse set in the specific plugin option called “eCommerce 360 cookie lifetime”.
If the user goes to checkout, the order will be tracked for the user that received that specific information.
Now your MailChimp page should be populated as you can see above, depending on the orders made by users coming from that campaign.
N.B. Order registration will be done as soon as it is placed or completed according to what you have specified in the option “Register after” available in the tab “Checkout”.
