      Lists buckets alphabetically by name

      When using an authorization token that is restricted to a bucket, you must include the bucketId or bucketName of that bucket in the request, or the request will be denied.

      API Versions

      v2: Remove application key workaround (Sept 13, 2018)

      Listing buckets will always return all buckets, unless you ask for just one by specifying bucketName or bucketId. If you ask for all buckets and your application key is restricted to one bucket, the call is unauthorized.

      v1: Workaround for existing applications and application keys (August 9, 2018)

      When using an application key that is restricted to a bucket, a request to list all buckets will return just that one bucket instead of returning "unauthorized".

      v1: Application keys (July 26, 2018)

      New optional bucketName and bucketId parameters to b2_list_buckets provide a way to get information about just one bucket. This is useful when using an application key that allows access to only one bucket.

      v1: Original release (September 22, 2015)

      B2 Cloud Storage was released.

      Header parameters
      Authorization
      stringRequired

      An account authorization token, obtained from b2_authorize_account.
      The token must have the listBuckets capability.

      Body parameters
      object
      accountId
      string Required

      Your account ID.

      ExampleACCOUNT_ID
      bucketId
      string

      When bucketId is specified, the result will be a list containing just this bucket, if it's present in the account, or no buckets if the account does not have a bucket with this ID.

      Example4a48fe8875c6214145260818
      bucketName
      string

      When bucketName is specified, the result will be a list containing just this bucket, if it's present in the account, or no buckets if the account does not have a bucket with this name.

      ExamplemyBucketName
      bucketTypes
      Array of string

      If present, this will be used as a filter for bucket types returned in the list buckets response. If not present, only buckets with bucket types "allPublic", "allPrivate" and "snapshot" will be returned. A special filter value of ["all"] will return all bucket types.

      If present, it must be in the form of a json array of strings containing valid bucket types in quotes and separated by a comma. Valid bucket types include "allPrivate", "allPublic", "restricted", "snapshot", "shared", and other values added in the future.

      A bad request error will be returned if "all" is used with other bucketTypes, bucketTypes is empty, or invalid bucketTypes are requested.

      Example[ "allPublic", "allPrivate" ]
      string
      Responses
      200

      The request succeeded.


      The response headers include the Content-Type that was specified when the file was uploaded. They also include the X-Bz-FileName and X-Bz-Content-Sha1 headers, plus X-Bz-Info-* headers for any custom file info that was provided with the upload. The X-Bz-FileName uses percent-encoding, as if it were a URL parameter.
