# Additional Attributes

The `additional-attributes` API provides configurable [AttributeSets](/api-reference/additional-attributes/attribute-sets.md) for departments and roles. Each set contains [AttributeFields](/api-reference/additional-attributes/attribute-fields.md) that collect the additional values.

An attribute field gets its input behavior from an [AttributeFieldType](/api-reference/additional-attributes/attribute-field-types.md). Administrators can add [AttributeFieldValidations](/api-reference/additional-attributes/attribute-field-validations.md) based on the available [AttributeFieldValidationTypes](/api-reference/additional-attributes/attribute-field-validation-types.md), prefill values through [AttributeFieldDefaultValueSources](/api-reference/additional-attributes/attribute-field-default-value-sources.md), and control conditional visibility with [AttributeFieldDisplayConditions](/api-reference/additional-attributes/attribute-field-display-conditions.md).
