Hi Hubspot support,
I am using Hubsport Web API for Form Submit: https://developers.hubspot.com/docs/methods/forms/submit_form
Sometimes it creates a new Contact, sometimes it updates an existing Contact.
For example, First and Last names are updated, while email contains all values from previous submissions.
My questions are:
- What is the contact behavior on Form Submit?
- When a new contact is created and when existing is updated?
- What is Contact unique property? IP address? HubSpot tracking cookie? Email?
- Why some fields are updated (names) and some concatenated (email) from prev submissions? Can this be changed?
