# ListObjectVersions

`GET /{bucket}?versions`

Lists the versions and delete markers in a bucket.

Returns the versions and delete markers in key order, then in version ID order. Version IDs are random, so the order within a key is not by time. Use IsLatest and LastModified to find the newest version.

- Role: Viewer or higher.
- Support: supported.
- Auth: AWS Signature Version 4 with your API key. See [S3 API](/api/s3.md).
- Lists live versions and delete markers, with key and version markers.
- Storage ignores `delimiter`. The response has no CommonPrefixes.

## Errors

Any request can also get the common errors on [S3 API](/api/s3.md).

### 404 · `NoSuchBucket`

No bucket has this name, or the bucket was deleted.

Check the bucket name. ListBuckets shows the buckets of the workspace.

### 403 · `AccessDenied`

The key does not have the role for this operation, or the bucket is in another workspace.

Use a key of the workspace that owns the bucket, with the role above.
