Which forms are created through the integration on the HubSpot portal?

 The integration only creates a Hubspot form with the name “Checkout form”. This form is responsible for creation of contact on Hubspot with basic contact properties like Email, First and Last name. It triggers when someone submits the checkout form of a WooCommerce website.

The integration uses Hubspot tracking script for tracking user data like page views on WooCommerce website. This script creates HTML forms with the <form> tag, present on the WooCommerce website as non-Hubspot forms on the Hubspot portal. You might see some non-Hubspot forms whose names are like “.checkout, .WooCommerce-checkout, .processing”. Please note our integration is not responsible for creating these forms on Hubspot, the integration uses Hubspot tracking script which allows us to create these non-Hubspot forms.
