# ListObjectVersions
<a name="API_ListObjectVersions"></a>

**Note**  
This operation is not supported for directory buckets.

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

**Important**  
 To use this operation, you must have permission to perform the `s3:ListBucketVersions` action. Be aware of the name difference. 

**Note**  
 A `200 OK` response can contain valid or invalid XML. Make sure to design your application to parse the contents of the response and handle it appropriately.

To use this operation, you must have READ access to the bucket.

The following operations are related to `ListObjectVersions`:
+  [ListObjectsV2](https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjectsV2.html) 
+  [GetObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html) 
+  [PutObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutObject.html) 
+  [DeleteObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteObject.html) 

**Important**  
You must URL encode any signed header values that contain spaces. For example, if your header value is `my file.txt`, containing two spaces after `my`, you must URL encode this value to `my%20%20file.txt`.

## Request Syntax
<a name="API_ListObjectVersions_RequestSyntax"></a>

```
GET /?versions&delimiter=Delimiter&encoding-type=EncodingType&key-marker=KeyMarker&max-keys=MaxKeys&prefix=Prefix&version-id-marker=VersionIdMarker HTTP/1.1
Host: Bucket.s3.amazonaws.com

## URI Request Parameters
<a name="API_ListObjectVersions_RequestParameters"></a>

The request uses the following URI parameters.

 ** [Bucket](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-header-Bucket"></a>
The bucket name that contains the objects.   
Required: Yes

 ** [delimiter](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-uri-querystring-Delimiter"></a>
A delimiter is a character that you specify to group keys. All keys that contain the same string between the `prefix` and the first occurrence of the delimiter are grouped under a single result element in `CommonPrefixes`. These groups are counted as one result against the `max-keys` limitation. These keys are not returned elsewhere in the response.  
 `CommonPrefixes` is filtered out from results if it is not lexicographically greater than the key-marker.

 ** [encoding-type](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-uri-querystring-EncodingType"></a>
Encoding type used by Amazon S3 to encode the [object keys](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html) in the response. Responses are encoded only in UTF-8. An object key can contain any Unicode character. However, the XML 1.0 parser can't parse certain characters, such as characters with an ASCII value from 0 to 10. For characters that aren't supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response. For more information about characters to avoid in object key names, see [Object key naming guidelines](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html#object-key-guidelines).  
When using the URL encoding type, non-ASCII characters that are used in an object's key name will be percent-encoded according to UTF-8 code values. For example, the object `test_file(3).png` will appear as `test_file%283%29.png`.
Valid Values: `url` 

 ** [key-marker](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-uri-querystring-KeyMarker"></a>
Specifies the key to start with when listing objects in a bucket.

 ** [max-keys](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-uri-querystring-MaxKeys"></a>
Sets the maximum number of keys returned in the response. By default, the action returns up to 1,000 key names. The response might contain fewer keys but will never contain more. If additional keys satisfy the search criteria, but were not returned because `max-keys` was exceeded, the response contains `<isTruncated>true</isTruncated>`. To return the additional keys, see `key-marker` and `version-id-marker`.

 ** [prefix](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-uri-querystring-Prefix"></a>
Use this parameter to select only those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys. (You can think of using `prefix` to make groups in the same way that you'd use a folder in a file system.) You can use `prefix` with `delimiter` to roll up numerous objects into a single result under `CommonPrefixes`. 

 ** [version-id-marker](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-uri-querystring-VersionIdMarker"></a>
Specifies the object version you want to start listing from.

 ** [x-amz-expected-bucket-owner](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-header-ExpectedBucketOwner"></a>
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code `403 Forbidden` (access denied).

 ** [x-amz-optional-object-attributes](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-header-OptionalObjectAttributes"></a>
Specifies the optional fields that you want returned in the response. Fields that you do not specify are not returned.  
Valid Values: `RestoreStatus` 

 ** [x-amz-request-payer](#API_ListObjectVersions_RequestSyntax) **   <a name="AmazonS3-ListObjectVersions-request-header-RequestPayer"></a>
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for the corresponding charges. For information about downloading objects from Requester Pays buckets, see [Downloading Objects in Requester Pays Buckets](https://docs.aws.amazon.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html) in the *Amazon S3 User Guide*.  
This functionality is not supported for directory buckets.
Valid Values: `requester`

### Sample Request: Using the delimiter and prefix Parameters
<a name="API_ListObjectVersions_Example_11"></a>

Assume you have the following keys in your bucket, `example-bucket`.

 `photos/2006/January/sample.jpg` 

 `photos/2006/February/sample.jpg` 

 `photos/2006/March/sample.jpg` 

 `videos/2006/March/sample.wmv` 

 `sample.jpg` 

The following `GET` versions request specifies the `delimiter` parameter with the value `/`.

```
GET /?versions&delimiter=/ HTTP/1.1
Host: example-bucket.s3.<Region>.amazonaws.com
Date: Wed, 02 Feb 2011 20:34:56 GMT
Authorization: authorization string
```

### Sample Response
<a name="API_ListObjectVersions_Example_12"></a>

The list of keys from the specified bucket is shown in the following response.

The response returns the `sample.jpg` key in a `Version` element. However, because all the other keys contain the specified delimiter, a distinct substring, from the beginning of the key to the first occurrence of the delimiter, from each of these keys is returned in a `CommonPrefixes` element. The key substrings, `photos/` and `videos/`, in the `CommonPrefixes` element indicate that there are one or more keys with these key prefixes.

This is a useful scenario if you use key prefixes for your objects to create a logical folder-like structure. In this case, you can interpret the result as the folders `photos/` and `videos/` have one or more objects.

```

  </CommonPrefixes>
  <CommonPrefixes>
    <Prefix>videos/</Prefix>
  </CommonPrefixes>
</ListVersionsResult>
```

### Example
<a name="API_ListObjectVersions_Example_13"></a>

In addition to the `delimiter` parameter, you can filter results by adding a `prefix` parameter as shown in the following request.

```
GET /?versions&prefix=photos/2006/&delimiter=/ HTTP/1.1
Host: example-bucket.s3.<Region>.amazonaws.com
Date: Wed, 02 Feb 2011 19:34:02 GMT
Authorization: authorization string
```

### Example
<a name="API_ListObjectVersions_Example_14"></a>

In this case, the response will include only object keys that start with the specified prefix. The value returned in the `CommonPrefixes` element is a substring from the beginning of the key to the first occurrence of the specified delimiter after the prefix. 

**Note**  
If you created folders by using the Amazon S3 console, you will see an additional 0-byte object with a key of `photos/2006/`. This object is created because of the way that the console supports folder structures. For more information, see [Organizing objects in the Amazon S3 console using folders](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-folders.html) in the *Amazon S3 User Guide*.
