Tagging Orders from Woocommerce

Hi! I’m having issues completing the integration between Keap and my wordpress website where I use woocomerce for all payments. I’m using the WP Infusionsoft WooCommerce Plugin and have set up the forms to include the information I want to send across to Keap. I basically want any new/current contact to be tagged with the product they have purchased, but I can’t seem to complete this! Any help please?
