API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Container for the parameters to the DeleteObject operation. Removes an object from a bucket. The behavior depends on the bucket's versioning state:

  • Directory buckets - S3 Versioning isn't enabled and supported for directory buckets. For this API operation, only the null value of the version ID is supported by directory buckets. You can only specify null to the versionId query parameter in the request.

  • Directory buckets - For directory buckets, you must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com/key-name. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

To remove a specific version, you must use the versionId query parameter. Using this query parameter permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header x-amz-delete-marker to true.

If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS. For more information about MFA Delete, see Using MFA Delete in the Amazon S3 User Guide. To see sample requests that use versioning, see Sample Request.

Directory buckets - MFA delete is not supported by directory buckets.

You can delete objects by explicitly calling DELETE Object or calling (PutBucketLifecycle) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject, s3:DeleteObjectVersion, and s3:PutLifeCycleConfiguration actions.

Directory buckets - S3 Lifecycle is not supported by directory buckets.

Permissions

  • General purpose bucket permissions - The following permissions are required in your policies when your DeleteObjects request includes specific headers.

    • s3:DeleteObject - To delete an object from a bucket, you must always have the s3:DeleteObject permission.

    • s3:DeleteObjectVersion - To delete a specific version of an object from a versioning-enabled bucket, you must have the s3:DeleteObjectVersion permission.

  • Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

Public Method DeleteObjectRequest()

Properties

NameTypeDescription
Public Property BucketName System.String

Gets and sets the property BucketName.

The bucket name of the bucket containing the object.

Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, 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 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 Using access points in the Amazon S3 User Guide.

Access points and Object Lambda access points are not supported by directory buckets.

S3 on Outposts - When you use 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 AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.

Public Property BypassGovernanceRetention System.Boolean

Gets and sets the property BypassGovernanceRetention.

Indicates whether S3 Object Lock should bypass Governance-mode restrictions to process this operation. To use this header, you must have the s3:BypassGovernanceRetention permission.

This functionality is not supported for directory buckets.

Public Property ExpectedBucketOwner System.String

Gets and sets the property ExpectedBucketOwner.

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).

Public Property Key System.String

Gets and sets the property Key.

Key name of the object to delete.

Public Property MfaCodes Amazon.S3.Model.MfaCodes

Gets and sets the property MFA.

The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.

This functionality is not supported for directory buckets.

Public Property RequestPayer Amazon.S3.RequestPayer

Gets and sets the property RequestPayer.

Public Property VersionId System.String

Gets and sets the property VersionId.

Version ID used to reference a specific version of the object.

For directory buckets in this API operation, only the null value of the version ID is supported.

Examples

This example shows how to delete an object.

DeleteObject sample


// Create a client
AmazonS3Client client = new AmazonS3Client();

// Create a DeleteObject request
DeleteObjectRequest request = new DeleteObjectRequest
{
    BucketName = "SampleBucket",
    Key = "Item1"
};

// Issue request
client.DeleteObject(request);
