# Bulk update custom field options

`PATCH /v3/custom_field_options/bulk`

Asynchronously edit the label, sort order, or external id of many options in one call — most often used to reorder a dropdown after an upstream HRIS reshuffle or to rename options en masse. Each item must include `id`; the remaining fields are treated as a partial update. Per-item success or failure is reported through the bulk-status endpoint.

## Request body

- object
  - `callback_url` string — Optional HTTPS URL Greenhouse will POST to when every row in `data` has finished. Omit to poll `GET /v3/bulk_requests/{bulk_action_uuid}` instead.
  - `data` object[], required — Array of single-resource update payloads to process. Each item must include the integer `id` of the record to update and otherwise match the schema of the matching non-bulk PATCH endpoint; rows are validated and executed independently.
    - `name` string — New display label for the option. Must be unique among active options on the same custom field; renaming to collide with an archived option's name returns 422 — POST a new option with that name to reactivate it instead.
    - `sort_order` integer — New display position within the dropdown. Lower values render first. Partners reorganizing dropdowns typically PATCH `sort_order` on every affected option in a single bulk update.
    - `external_id` string — New caller-supplied identifier from the partner's source system. Send an empty string to clear a previously stored value.
    - `id` integer, required

## Response `202`

Accepted

- object
  - `bulk_action_uuid` string — UUID assigned to the new bulk request. Use this with `GET /v3/bulk_requests/{bulk_action_uuid}` to monitor progress and retrieve per-row results.
  - `status` string — Initial lifecycle state of the new bulk request, typically `building` immediately after creation. See the bulk request response schema for the full set of values.
  - `status_url` string — Relative path that returns the current status of the bulk request. Append this to your Harvest base URL to fetch the latest state.
