After you submit a REST API request to create a business entity record, Informatica MDM Hub calculates the trust score of the field. You can submit a REST API request for empty fields with calculated trust scores. You must specify double quotation marks in the request body.

The following JSON code sample requests the empty Gender Code field with a calculated trust score:

{
	"firstName": "Sasha",
	"genderCd": ""
}

If you use null instead of double quotation marks, Informatica MDM Hub does not calculate the field trust score.
