# Get the application theme

`GET /v1/branding/applications/{application_id}` · permission `branding:read`

Returns the theme draft of one application. Its tokens override the environment theme on that application's hosted pages. An application without its own draft returns an empty theme and `ETag: "0"`.

## Request

| Field | Type | Required | Description |
|---|---|---|---|
| `application_id` | path | yes | `app_…` id. |

## Response

`200 OK` with the scope's theme draft and its `ETag` (each scope has its own version).

```json
{
  "theme": {"logo": "logo_acme", "light": {"color": {"primary": "#0a3d91"}}},
  "updated_at": "2026-10-05T09:30:00.123456Z"
}
```

## Errors

| 403 | `insufficient_permissions` | The credential lacks the required permission. |
| 429 | `rate_limited` | The rate limit was exceeded; retry after the `Retry-After` period. |
