We currently don't have any HubSpot forms or forms connected to HubSpot via the Forms API on our website. We currently have Segment installed on our website, which creates leads in Salesforce when a lead/contact submits a form on the website.
If we were to connect that same form to a HubSpot form via the Forms API, but didn't remove the Segment integration or Salesforce lead creation. Would there be a new lead created in both systems (HubSpot & Salesforce)? Would the sync handle matching them, or would duplicates be created in one system or the other?
