getObjectRetention method

Future<GetObjectRetentionOutput> getObjectRetention({ required String bucket, required String key, String? expectedBucketOwner, RequestPayer? requestPayer, String? versionId, })

Retrieves an object's retention settings. For more information, see Locking Objects.

This action is not supported by Amazon S3 on Outposts.

Parameter bucket : The bucket name containing the object whose retention settings you want to retrieve.

When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this operation with an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide.

Parameter key : The key name for the object whose retention settings you want to retrieve.

Parameter expectedBucketOwner : The account id of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.

Parameter versionId : The version ID for the object whose retention settings you want to retrieve.
