listUploads method

Written by
Updated at March 19, 2025

Returns a list of current multipart uploads.

The response may not contain more than 1,000 elements. If there are more uploads, Object Storage will return the IsTruncated element, as well as the NextKeyMarker and NextUploadIdMarker elements to use for the key-marker and upload-id-marker parameters of a subsequent request.

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

Request

GET /{bucket}?uploads HTTP/2

Path parameters

Parameter Description
bucket Bucket name.

Request parameters

Parameter Description
delimiter Delimiter character.

If this parameter is specified, Object Storage interprets the key as the path to the file with folder names separated by a delimiter. The user gets a list of files and folders in the root of the bucket. Files will be output in the Uploads 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.
max-uploads Maximum number of uploads in a response.

By default, Object Storage outputs no more than 1,000 keys. Use this parameter if you need less than 1,000 keys 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 objects if their number exceeds max-keys, run multiple requests to Object Storage with the key-marker parameter, where the key-marker of each request is equal to the value of the NextKeyMarker element in the previous response.
key-marker Key. The output begins with the key that follows the one specified in the parameter value.

Use it together with upload-id-marker for output filtering.

If upload-id-marker is specified, the output will also contain key-marker.
prefix String to start the key from.

Object Storage selects only those keys which start with prefix.
upload-id-marker Upload ID.

The first upload in the output is the one whose ID follows the upload specified in this parameter. The key-marker parameter is used in processing, i.e., the output includes uploads filtered by both upload-id-marker and key-marker.

If key-marker is not specified, upload-id-marker is ignored.
uploads Flag indicating a multipart upload operation.
