# Get a case attachment

Authentication: required

Availability: Planned

- Server: `https://{kibana_url}`

## Paths

- `GET` `/api/cases/{caseId}/attachments/{attachmentId}`
- `GET` `/s/{space_id}/api/cases/{caseId}/attachments/{attachmentId}`

#### Path parameters

- `space_id` (string) — optional
  An identifier for the space. If `space_id` is not provided in the URL, the default space is used. Refer to [Spaces](https://www.elastic.co/docs/deploy-manage/manage-spaces) for more information.
- `caseId` (string) — required
  The identifier for the case. To retrieve case IDs, use the search cases (`_find)` API. All non-ASCII characters must be URL encoded.
  Example: `9c235210-6834-11ea-a78c-6ffb38a34414`
- `attachmentId` (string · max length: 512) — required
  The ID of the attachment, which is its `id` field, not `attachmentId`. To get it, use the find case attachments API.
  Example: `71ec1870-725b-11ea-a0b2-c51ea50a58e2`

## Description

## Responses

Indicates a successful call.

`application/json`

- `attachmentId` (union oneOf)
  The ID of the attached item, such as an alert or a dashboard. To attach several alerts, use an array. This isn't the attachment's own ID (`id`).
  One of: `string[]` or `string`
- `created_at` (string · format: date-time)
- `created_by` (object)
  - `email` (string) — nullable
  - `full_name` (string) — nullable
  - `profile_uid` (string)
  - `username` (string) — nullable
- `data` (object) — nullable
  The attachment's content. Required for comments, where `content` is the comment text (up to 30,000 characters). In requests, it can be up to 524,288 characters when serialized as JSON and nest up to 30 levels deep.
- `id` (string)
  The attachment identifier.
- `metadata` (object) — nullable
  Extra details about the attachment. For alerts, this is the alert's index and rule. Required for some types, such as `dashboard`. In requests, it can be up to 524,288 characters when serialized as JSON and nest up to 30 levels deep.
- `owner` (enum)
  The application that owns the cases: Stack Management, Observability, or Elastic Security.
  Values: `cases`, `observability`, `securitySolution`
