ActiveWoo is a complete integration/plugin between WooCommerce and ActiveCampaign.
Once the plugin is installed, each time a customer makes a purchase, ActiveWoo will automatically add or update the Contact in your ActiveCampaign, and then apply a tag for each product that the customer purchased.
ActiveWoo can also keep a running total of how much each customer has spent on your site.
ActiveWoo adds a note to the contact with a link back to the order in WooCommerce, making your customer support a snap.
Tags are automatically created/added to ActiveCampaign by using the SKU of the product in WooCommerce and/or the product category. If you already have SKU's & product categories setup, then all you need to do is put in your API details, and the rest is automagic!
