AWS SDK Version 3 for .NET
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 DeleteBucketPolicy operation. Deletes the policy of a specified bucket.

Directory buckets - For directory buckets, you must make requests for this API operation to the Regional endpoint. These endpoints support path-style requests in the format https://s3express-control.region_code.amazonaws.com/bucket-name. Virtual-hosted-style requests aren't supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Permissions

If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must both have the DeleteBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have DeleteBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

To ensure that bucket owners don't inadvertently lock themselves out of their own buckets, the root principal in a bucket owner's Amazon Web Services account can perform the GetBucketPolicy, PutBucketPolicy, and DeleteBucketPolicy API actions, even if their bucket policy explicitly denies the root principal's access. Bucket owner root principals can only be blocked from performing these API actions by VPC endpoint policies and Amazon Web Services Organizations policies.

  • General purpose bucket permissions - The s3:DeleteBucketPolicy permission is required in a policy. For more information about general purpose buckets bucket policies, see Using Bucket Policies and User Policies in the Amazon S3 User Guide.

  • Directory bucket permissions - To grant access to this API operation, you must have the s3express:DeleteBucketPolicy permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.

Bucket names must also 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
Public Property ExpectedBucketOwner System.String
