Retrieves a list of buckets for a given project, ordered in the list lexicographically by name.

Required permissions

The authenticated user must have the storage.buckets.list IAM permission to use this method. To list IAM policies for a bucket, the authenticated user must also have the storage.buckets.getIamPolicy permission.


HTTP request

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

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

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


Parameter name Value Description
Required query parameters
project string A valid API project identifier.
Optional query parameters
maxResults unsigned integer Maximum number of buckets to return in a single response. The service may return fewer results than maxResults so the presence of nextPageToken should always be checked. The service limits to:
  • 200 items if projection=full.
  • 1,000 items if projection=noAcl.
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 (bucket) 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 new bucket before using a pageToken to continue listing, you will not see the new bucket in subsequent listing results if it is in part of the bucket namespace already listed.
prefix string Filter results to buckets whose names begin with this prefix.
projection string Set of properties to return. Defaults to noAcl.

Acceptable values are:
  • full: Include all properties.
  • noAcl: Omit owner, acl, and defaultObjectAcl properties.

Request body

Do not supply a request body with this method.


If successful, this method returns a response body with the following structure:

  "kind": "storage#buckets",
  "nextPageToken": string,
  "items": [
    buckets Resource
Property name Value Description Notes
kind string The kind of item this is. For lists of buckets, this is always "storage#buckets".
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 bucket 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 buckets.
