listObjectVersions method

Written by
Updated at October 28, 2024

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 to the request, 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 the list of files and folders in the folder named prefix.
encoding-type Encoding of server response.

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

Possible values: url.
key-marker Key to start the output from.

In the resulting output, Object Storage will leave the keys starting from the one following 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 less 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 contains <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.

You can use this parameter at the same time 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 resulting output, Object Storage will leave the versions starting from the one following version-id-marker.

Headers

Element Description
ListVersionsResult Root element
CommonPrefixes Key name part identified when processing the delimiter and prefix query parameters.

Path: /ListVersionsResult/CommonPrefixes.
DeleteMarker Container for an object that is a delete marker.

Path: /ListVersionsResult/DeleteMarker.
Delimiter Value of the delimiter query 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 Marker indicating that a list is incomplete.

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

Path: /ListVersionsResult/KeyMarker.
MaxKeys Value of the max-keys query parameter.

Path: /ListBucketResult/MaxKeys.
Name Bucket name.

Path: /ListBucketResult/Name.
NextKeyMarker Value to insert in the key-marker query parameter to get the next part of the list if the entire list does not fit in the current response.

Path: /ListBucketResult/NextMarker.
NextVersionIdMarker Value to insert in the version-id-marker query parameter to get the next part of the list if the entire list does not fit in the current response.

Path: /ListBucketResult/NextVersionIdMarker.
Prefix Value of the prefix query parameter.

Path: /ListBucketResult/Prefix.
Version Object version.

Path: /ListBucketResult/Version.
