Request

HTTP request

GET https://storage.googleapis.com/storage/v1/b/bucket/folders

In addition to standard query parameters, the following parameters apply to this method.

To see an example of how to include query parameters in a request, see the JSON API Overview page.

Parameters

Parameter name Value Description Path parameters bucket string The parent bucket of the folder. Optional query parameters prefix string Filter results to folders whose names begin with this prefix. If not set or set to an empty string, the method lists all folders in the bucket. If set to a non-empty string, the value must end with a /. maxResults unsigned integer The maximum number of folders to return in a single response. The service may return fewer results than maxResults so the presence of nextPageToken should always be checked. pageToken string

A previously-returned page token representing part of the larger set of results to view.

The pageToken is an encoded field containing the name of the last item (a folder) in the returned list. In a subsequent request using the pageToken, items that come after the pageToken are shown (up to maxResults).

If you start a listing and then create a folder before using a pageToken to continue listing, you will not see the new folder in subsequent listing results if it is in part of the folder namespace already listed.

delimiter string

Returns results in a directory-like mode, with / being the only supported value for the delimiter. If set, the method returns folders that exactly match the prefix or are one level below the given prefix. The folder matching the prefix is also returned as part of the response.

startOffset string Filter results to folders whose names are lexicographically equal to or after startOffset. If endOffset is also set, the folders listed have names between startOffset (inclusive) and endOffset (exclusive). endOffset string Filter results to folders whose names are lexicographically before endOffset. If startOffset is also set, the folders listed have names between startOffset (inclusive) and endOffset (exclusive).

Request body

Don't supply a request body with this method.

Response

If successful, this method returns a response body with the following structure, where the list of folders are included in the items attribute and sorted alphabetically by order:

{
  "kind": "storage#folders"
  "nextPageToken": string,
  "items": [
    Folder resources
  ]
}
Property name Value Description Notes
kind string The kind of item this is. For lists of folders, this is always storage#folders.
nextPageToken string The continuation token. Provide this value as the pageToken of a subsequent request in order to return the next page of results. Note that the next page may be empty. If this is the last page of results, then no continuation token is returned. The presence of this parameter in the response should always be checked to ensure a complete listing of all the results.

The nextPageToken is the name of the last folder in the returned list. In a subsequent list request using the pageToken, items that come after the token are shown (up to maxResults).
items[] list The list of folders.
