Hey Zoho Community!

I have a 4 page zoho form with different data being collected throughout but I'd like to know how I can make it so the moment the first page (essentially Name and Email) is complete the user data is already created in Zoho CRM. Then during the reminder of the form the Zoho CRM record is just updated with the data inputs. 

It is also important that duplicates cannot be created with this form and need some advice there. 

Thanks so much in advance!!!
