## Paths

- `GET` `/api/cases/field_definitions`

- [Api key auth](/elastic/docs-builder/docs/4371/api/doc/kibana-serverless/authentication#apikeyauth)

## Description

Refer to [Spaces](https://www.elastic.co/docs/deploy-manage/manage-spaces) for more information.

Returns a paginated list of field definitions (field library entries) for the given owner. Requires the Cases feature to be enabled in the space.

## Query String Parameters

- `owner` (union string | [] string)
  The application that owns the field definitions (for example `cases`, `observability`, or `securitySolution`). Required.
  One of: `string` or `string[]`
- `isGlobal` (boolean)
  When true, returns only global field definitions (rendered on every case). When false, returns all definitions. Omit to return all.
- `page` (integer · default: 1)
  The page number to return.
- `perPage` (integer · max: 100 · default: 20)
  The number of items to return. Limited to 100 items.
- `sortField` (enum)
  The field to sort by. When omitted, results are sorted by `fieldDefinitionId` ascending and `sortOrder` is ignored.
  Values: `name`, `owner`, `isGlobal`, `displayOrder`
- `sortOrder` (enum  · default: desc)
  Determines the sort order.
  Values: `asc`, `desc`
- `search` (string · max: 1000)
  A case-insensitive substring to match against each definition's `name` and `description` fields. Definitions where neither field contains the substring are excluded.
