Sets the supplied tag-set to an object that already exists in a bucket.

A tag is a key-value pair. You can associate tags with an object by sending a PUT request against the tagging subresource that is associated with the object. You can retrieve tags by sending a GET request. For more information, see GetObjectTagging.

For tagging-related restrictions related to characters and encodings, see Tag Restrictions. Note that Amazon S3 limits the maximum number of tags to 10 tags per object.

To use this operation, you must have permission to perform the s3:PutObjectTagging action. By default, the bucket owner has this permission and can grant this permission to others.

To put tags of any other version, use the versionId query parameter. You also need permission for the s3:PutObjectVersionTagging action.

For information about the Amazon S3 object tagging feature, see Object Tagging.

Path parameters

Bucketstring required
<p>The bucket name containing the object. </p> <p>When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form <i>AccessPointName</i>-<i>AccountId</i>.s3-accesspoint.<i>Region</i>.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-access-points.html">Using access points</a> in the <i>Amazon S3 User Guide</i>.</p> <p>When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form <code> <i>AccessPointName</i>-<i>AccountId</i>.<i>outpostID</i>.s3-outposts.<i>Region</i>.amazonaws.com</code>. When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/S3onOutposts.html">Using Amazon S3 on Outposts</a> in the <i>Amazon S3 User Guide</i>.</p>

Headers

Content-MD5string
<p>The MD5 hash for the request body.</p> <p>For requests made using the Amazon Web Services Command Line Interface (CLI) or Amazon Web Services SDKs, this field is calculated automatically.</p>
x-amz-sdk-checksum-algorithm'CRC32' | 'CRC32C' | 'SHA1' | 'SHA256'
<p>Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding <code>x-amz-checksum</code> or <code>x-amz-trailer</code> header sent. Otherwise, Amazon S3 fails the request with the HTTP status code <code>400 Bad Request</code>. For more information, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/checking-object-integrity.html">Checking object integrity</a> in the <i>Amazon S3 User Guide</i>.</p> <p>If you provide an individual checksum, Amazon S3 ignores any provided <code>ChecksumAlgorithm</code> parameter.</p>
x-amz-expected-bucket-ownerstring

The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code <code>403 Forbidden</code> (access denied).

x-amz-request-payer'requester'

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests.
