GET

/{Bucket}/{Key}#uploadId

http://s3{dash-or-dot}{region}.amazonaws.com/{Bucket}/{Key}#uploadId

Lists the parts that have been uploaded for a specific multipart upload. This operation must include the upload ID, which you obtain by sending the initiate multipart upload request (see <a href="https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html">CreateMultipartUpload</a>). This request returns a maximum of 1,000 uploaded parts. The default number of parts returned is 1,000 parts. You can restrict the number of parts returned by specifying the <code>max-parts</code> request parameter. If your multipart upload consists of more than 1,000 parts, the response returns an <code>IsTruncated</code> field with the value of true, and a <code>NextPartNumberMarker</code> element. In subsequent <code>ListParts</code> requests you can include the part-number-marker query string parameter and set its value to the <code>NextPartNumberMarker</code> field value from the previous response. If the upload was created using a checksum algorithm, you will need to have permission to the <code>kms:Decrypt</code> action for the request to succeed. For more information on multipart uploads, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/uploadobjusingmpu.html">Uploading Objects Using Multipart Upload</a>. For information on permissions required to use the multipart upload API, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/mpuAndPermissions.html">Multipart Upload and Permissions</a>.
