This is my problem.I am having problems about Hubspot Form API. I have added data to form that I created by API code. But if I type email duplicate, The new contact will not create. It will update by that email. Do you have any way to solve it please, Thank you very much.
Contacts in HubSpot are unique by email; it's not possible to have two distinct HubSpot contacts with the same email address.
you are right, i haven't a simiiar problem
Thank you for responding
