# Delete a theme

`DELETE /clusters/{cluster_id}/themes/{theme_id}`

## Request

- Base URL: `http://localhost:8000`
- URL: `http://localhost:8000/clusters/{cluster_id}/themes/{theme_id}`
- Auth: API key in header `API-Key`

Deletes the theme package. Returns `409 Conflict` if the theme is assigned to a realm or application client. If the theme is currently deployed, Keycloak undeployment runs asynchronously; the response returns with `status: undeploying` and the theme is removed once complete. Poll GET until 404 to confirm deletion.

Required scope: `themes:write`

## Path parameters

- `cluster_id` string, uuid, required
- `theme_id` string, uuid, required

## Headers

- `API-Version` '2026-06-01.beta', required

## Response `202`

The request has been accepted for processing, but processing has not yet completed.

- Theme: A custom Keycloak theme package deployed to a cluster.
  - `id` string, uuid, required
  - `cluster_id` string, uuid, required
  - `name` string, required
  - `description` string
  - `version` string
  - `theme_types` ThemeType[], required: Keycloak theme types detected in the uploaded ZIP package.
  - `status` 'deploying' | 'deployed' | 'undeploying' | 'failed', required
  - `file_size` integer, required: Size of the uploaded theme archive in bytes.
  - `deployed_at` string, date-time: Timestamp of the most recent successful deployment to Keycloak.
  - `error_message` string: Error detail from the last failed deployment.
  - `directory` string: Directory name Keycloak serves this theme from. Use this exact value when setting a realm or application theme outside Skycloak. Valid once `status` is `deployed`. It changes when the theme content is replaced: realm theme settings that name the previous directory are moved automatically, but application themes set outside Skycloak are not and must be updated after a replace.
  - `restart_required` boolean: True when the theme's content was replaced under its exact name and Keycloak has not restarted since, so the previous content may still be served. Only workspaces that keep exact theme names replace content in place; for every other theme this is false.
  - `created_at` string, date-time, required
  - `updated_at` string, date-time, required
