Contact date of birth​

The Contact type now includes a nullable dateOfBirth field sourced from the contact's date of birth. Values use the YYYY-MM-DD calendar format with no time or timezone. A missing source value is returned as null.

The field is available in environments where the updated Contacts API and ETL are deployed.

See the Contact field reference for details.
