If a user is using ZohoForms iOS app to submitted the form, I understand that we pull out the user email by using ${zf:ADDED_EMAILID}. However, if we are using Zapier to integrate, how can we pull out this information?

It would be good that you could add first name and last name to the users.

And create the ability to autofill the first name, last name and email ID when the user is using the ZohoForms App.
