Hey Everyone!

New Programmer here:

The retrieve a contact endpoint specifies that it can also search a contact by unique property: "Retrieve a contact by its ID (contactId) or by a unique property (idProperty)."
https://developers.hubspot.com/docs/reference/api/crm/objects/contacts#get-%2Fcrm%2Fv3%2Fobjects%2Fcontacts%2F%7Bcontactid%7D


Does this unique property always have to be numerical or can this also be the email property from the contact which in itself is also unique?
