Written by

Returns metadata for all versions of objects in the bucket.
You can also use request parameters as a selection criterion to return metadata about a subset of object versions.

For more information on getting started with the API and the general request format, see How to use the S3 API.

Request

GET /{bucket}?versions&delimiter=Delimiter&encoding-type=EncodingType&key-marker=KeyMarker&max-keys=MaxKeys&prefix=Prefix&version-id-marker=VersionIdMarker HTTP/2

Path parameters

Parameter

Description

bucket

Bucket name

Query parameters

All parameters listed in the table are optional.

Parameter

Description

delimiter

Delimiter character.

If this parameter is specified, Object Storage interprets the key as the path to the file with folders separated by the delimiter character. In the response, the user will get a list of files and folders in the bucket. Files will be output in the Contents elements, and folders, in the CommonPrefixes elements.

If the request also specifies the prefix parameter, Object Storage will return a list of files and folders in the prefix folder.

encoding-type

Encoding of server responses.

Object Storage can encode responses in the format requested by the client.

The possible value is url.

key-marker

Key to start the output from.

In the output, Object Storage will leave the keys starting from the one that follows key-marker.

max-keys

Maximum number of elements in a response.

By default, Object Storage outputs no more than 1,000 Contents and CommonPrefixes elements. Use this parameter if you need fewer than 1,000 elements in a single response.

If the selection criteria are met by more keys than can fit into the output, the response will contain <IsTruncated>true</IsTruncated>.

To get all the output elements if their number exceeds max-keys, run multiple consecutive requests to Object Storage with the key-marker parameter, where the key-marker and version-id-marker of each request are equal to the values of the NextKeyMarker and NextVersionIdMarker elements in the previous response.

prefix

String to start the key from.

Object Storage selects only those keys which start with prefix.

Can be used together with delimiter. In this case, the output logic is the same as that specified in the delimiter parameter description.

version-id-marker

Object version to start the output from.

In the output, Object Storage will leave the versions starting from the one following version-id-marker.

Headings

Use only common headers in your requests.

Response

Headers

Responses can only contain common headers.

Response codes

For a list of possible responses, see Responses.

A successful response contains additional data in XML format with the schema described below.

Element

Description

ListVersionsResult

Root element.

CommonPrefixes

Key name part identified when processing the delimiter and prefix request parameters.

Path: /ListVersionsResult/CommonPrefixes.

DeleteMarker

Container for an object that is a delete marker.

Path: /ListVersionsResult/DeleteMarker.

Delimiter

Value of the delimiter request parameter.

Path: /ListVersionsResult/Delimiter.

EncodingType

Encoding used by Object Storage to provide a key in an XML response.

You will get this tag if the client provided the encoding-type parameter in the request.

Path: /ListVersionsResult/EncodingType.

IsTruncated

Tag that indicates that a list is incomplete.

If IsTruncated is true, this means Object Storage returned an incomplete list of parts.

Path: /ListVersionsResult/IsTruncated.

KeyMarker

Last key returned in the incomplete response.

Path: /ListVersionsResult/KeyMarker.

MaxKeys

Value of the max-keys request parameter.

Path: /ListBucketResult/MaxKeys.

Name

Bucket name.

Path: /ListBucketResult/Name.

NextKeyMarker

Value to substitute into the key-marker query parameter to get the next part of the list, if the entire list does not fit into the current response.

Path: /ListBucketResult/NextMarker.

NextVersionIdMarker

Value to substitute into the version-id-marker query parameter to get the next part of the list, if the entire list does not fit into the current response.

Path: /ListBucketResult/NextVersionIdMarker.

Prefix

Value of the prefix request parameter.

Path: /ListBucketResult/Prefix.

Version

Object version.

Path: /ListBucketResult/Version.

VersionIdMarker

Marks the last version of the key returned in the truncated response.
