Default Values

No/null/false value, empty object value and default value

To keep the payload of a response small, fields are not included in the answer in the following situations:

• fields that were not requested. These fields are not supplied.
• requested fields that the person requested does not have. These fields are not supplied. Example: the naam.voorvoegsel field is requested for a person who has no prefix in their name.
• requested fields have the false value. Example: the indicatieCurateleRegister field is requested for a person who has not been placed under guardianship.
• requested fields form a group of fields the person does not have. Example: verblijfstitel fields are requested for a person who has no residence permit.
• requested fields have the default value. In the BRP the default value is used to indicate that a piece of data is unknown. Example: the geboorte.plaats field is requested for a person whose place of birth is unknown.
• requested fields have no “in onderzoek” (under investigation) designation.

Requested lists are included in the answer even if they contain nothing. Example: if kinderen are requested for a person who has no children, the answer contains kinderen as an empty array.
