Beta

This feature is in beta and may not be available for all organizations.

Updates one custom field on a job posting. Returns the affected entry, including value: null when the field is empty.

Identify the field by fieldId or referenceIdentifier. If both are provided, they must identify the same field.

The effective actor must have permission to edit the job that owns the posting. Requires Job Posting custom fields to be enabled; private and API-only field permissions apply.

Supports String, LongText, Boolean, Number, Date, ValueSelect, MultiValueSelect and Url fields. Use null to clear an optional field; required fields cannot be cleared. Boolean false and Number 0 are values, not absences. Multi-select inputs replace the selected values.

Omitted fields and unrelated posting properties remain unchanged. Discover definitions with customField.list.

Requires the jobsWrite permission.
