## Path parameters

- `id` string, required

## Query parameters

- `delimiter` string

## Request body

- DropNamespaceRequest
  - `identity` Identity — Identity information of a request.
    - `api_key` string — API key for authentication. REST NAMESPACE ONLY This is passed via the `x-api-key` header.
    - `auth_token` string — Bearer token for authentication. REST NAMESPACE ONLY This is passed via the `Authorization` header with the Bearer scheme (e.g., `Bearer <token>`).
  - `context` unknown
  - `id` string[]
  - `mode` string — The mode for dropping a namespace, deciding the server behavior when the namespace to drop is not found. Case insensitive, supports both PascalCase and snake_case. Valid values are: - Fail (default): the server must return 400 indicating the namespace to drop does not exist. - Skip: the server must return 204 indicating the drop operation has succeeded.
  - `behavior` string — The behavior for dropping a namespace. Case insensitive, supports both PascalCase and snake_case. Valid values are: - Restrict (default): the namespace should not contain any table or child namespace when drop is initiated. If tables are found, the server should return error and not drop the namespace. - Cascade: all tables and child namespaces in the namespace are dropped before the namespace is dropped.

## Response `200`

Result of dropping a namespace

- DropNamespaceResponse
  - `context` unknown
  - `properties` unknown
  - `transaction_id` string[] — If present, indicating the operation is long running and should be tracked using DescribeTransaction

## Other responses

- `400` — Indicates a bad request error. It could be caused by an unexpected request body format or other forms of request validation failure, such as invalid json. Usually serves application/json content, although in some cases simple text/plain content might be returned by the server's middleware.
- `401` — Unauthorized. The request lacks valid authentication credentials for the operation.
- `403` — Forbidden. Authenticated user does not have the necessary permissions.
- `404` — A server-side problem that means can not find the specified resource.
- `409` — The request conflicts with the current state of the target resource.
- `503` — The service is not ready to handle the request. The client should wait and retry. The service may additionally send a Retry-After header to indicate when to retry.
- `5XX` — A server-side problem that might not be addressable from the client side. Used for server 5xx errors without more specific documentation in individual routes.
