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]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.
