DeleteObjectCommand

Removes an object from a bucket. The behavior depends on the bucket's versioning state:

If bucket versioning is not enabled, the operation permanently deletes the object.
If bucket versioning is enabled, the operation inserts a delete marker, which becomes the current version of the object. To permanently delete an object in a versioned bucket, you must include the object’s versionId in the request. For more information about versioning-enabled buckets, see Deleting object versions from a versioning-enabled bucket .
If bucket versioning is suspended, the operation removes the object that has a null versionId, if there is one, and inserts a delete marker that becomes the current version of the object. If there isn't an object with a null versionId, and all versions of the object have a versionId, Amazon S3 does not remove the object and only inserts a delete marker. To permanently delete an object that has a versionId, you must include the object’s versionId in the request. For more information about versioning-suspended buckets, see Deleting objects from versioning-suspended buckets .

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://amzn-s3-demo-bucket.s3express-zone-id.region-code.amazonaws.com/key-name . Path-style requests are not supported. For more information about endpoints in Availability Zones, see Regional and Zonal endpoints for directory buckets in Availability Zones in the Amazon S3 User Guide. For more information about endpoints in Local Zones, see Concepts for directory buckets in Local Zones 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-zone-id.region-code.amazonaws.com.

The following action is related to DeleteObject:

PutObject

Example Syntax

Use a bare-bones client and the command you need to make an API call.

import { S3Client, DeleteObjectCommand } from "@aws-sdk/client-s3"; // ES Modules import
// const { S3Client, DeleteObjectCommand } = require("@aws-sdk/client-s3"); // CommonJS import
const client = new S3Client(config);
const input = { // DeleteObjectRequest
  Bucket: "STRING_VALUE", // required
  Key: "STRING_VALUE", // required
  MFA: "STRING_VALUE",
  VersionId: "STRING_VALUE",
  RequestPayer: "requester",
  BypassGovernanceRetention: true || false,
  ExpectedBucketOwner: "STRING_VALUE",
  IfMatch: "STRING_VALUE",
  IfMatchLastModifiedTime: new Date("TIMESTAMP"),
  IfMatchSize: Number("long"),
};
const command = new DeleteObjectCommand(input);
const response = await client.send(command);
// { // DeleteObjectOutput
//   DeleteMarker: true || false,
//   VersionId: "STRING_VALUE",
//   RequestCharged: "requester",
// };
