# List namespaces

`GET /v1/namespace/{id}/list`

List all child namespace names of the parent namespace `id`.

REST NAMESPACE ONLY
REST namespace uses GET to perform this operation without a request body.
It passes in the `ListNamespacesRequest` information in the following way:
- `id`: pass through path parameter of the same name
- `page_token`: pass through query parameter of the same name
- `limit`: pass through query parameter of the same name

## Response `200`

A list of namespaces

- ListNamespacesResponse
  - `context` Context — Arbitrary context as key-value pairs. How to use the context is custom to the specific implementation. On a request, it carries caller-provided context to the implementation. On a response, it carries implementation-provided context back to the caller. REST NAMESPACE ONLY Context entries are mapped to and from HTTP headers using the `header.` prefix: - On a request, any entry whose key starts with `header.` is sent as an HTTP request header with the prefix stripped. For example, the entry `{"header.Authorization": "Bearer abc"}` is sent as the request header `Authorization: Bearer abc`. - On a response, every HTTP response header is returned as an entry whose key is the header name prefixed with `header.`. For example, the response header `x-request-id: abc123` is returned as the entry `{"header.x-request-id": "abc123"}`.
  - `namespaces` string[], required — The list of names of the child namespaces relative to the parent namespace `id` in the request.
  - `page_token` string, nullable — An opaque token that allows pagination for list operations (e.g. ListNamespaces). For an initial request of a list operation, if the implementation cannot return all items in one response, or if there are more items than the page limit specified in the request, the implementation must return a page token in the response, indicating there are more results available. After the initial request, the value of the page token from each response must be used as the page token value for the next request. Caller must interpret either `null`, missing value or empty string value of the page token from the implementation's response as the end of the listing results.

## 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.
- `406` — Not Acceptable / Unsupported Operation. The server does not support this operation.
- `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.
