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.

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.
